Nintendo Switch 2 owners hit a wall the original console never had: plug in an old microSD card from a first-generation Switch, and the system simply refuses to save or load a single digital game. That single design choice, requiring the new microSD Express standard instead of the familiar UHS-I cards, has turned a $50 accessory decision into a genuine research project. Three brands now dominate US retail shelves for Switch 2 storage: SanDisk, Samsung, and Lexar, each pricing the same 512GB capacity anywhere from $99.99 to $149.99.
This comparison pulls current August 2026 pricing, manufacturer-rated speeds, and real-world benchmark data from Tom’s Hardware, TechRadar, GamesRadar, and Nintendo’s own support documentation to answer the question every new Switch 2 owner is asking: which microSD Express card is actually worth buying, and does the “official” Nintendo license matter or is it just a markup.
It’s a decision that carries more weight than a typical accessory purchase for one simple reason: unlike almost every other console generation, there’s no cheap fallback option. You can’t grab whatever $15 no-name microSD card is on sale at the drugstore and call it a day. The Express requirement filters out the entire bargain-bin tier of the memory card market, which is exactly why brand, capacity, and price all matter more here than they ever did for the original Switch, the Steam Deck, or the PS5’s expansion slot.

Why the Switch 2 Ditched Regular MicroSD Cards
The original Nintendo Switch, launched in 2017, used standard UHS-I microSD cards capped at roughly 104 MB/s of theoretical bus bandwidth. That was plenty for a console running off a 32GB eMMC drive. The Nintendo Switch 2, which launched worldwide on June 5, 2025, ships with 256GB of internal UFS 3.1 flash storage, a much faster and more modern storage technology, and Nintendo built the expansion slot to match it rather than bottleneck it.
That meant adopting microSD Express, a standard built around the SD Association’s newer SD 7.x/8.0 specifications that layers a PCIe-based interface on top of the physical microSD form factor. In practice, this lets a microSD Express card theoretically approach speeds in the 800-900 MB/s range, an order of magnitude beyond what UHS-I cards could ever deliver, because the card talks to the host over PCIe lanes instead of the older SD bus protocol.
The catch, and the reason this comparison exists, is that Nintendo’s own support documentation is blunt about backward compatibility: “Inserting a microSD card that has been previously used on a Nintendo Switch console into a Nintendo Switch 2 console will not allow you to save or load digital games or save data.” Nintendo’s official compatibility table confirms it directly: standard microSD cards are marked “Cannot be used” on Switch 2, while microSD Express cards up to 2TB are marked “Can be used.” There’s no partial mode, no screenshots-only fallback. If the card isn’t Express-rated, the Switch 2 treats it as if no card is inserted at all for game storage purposes.
That single requirement is why SanDisk, Samsung, and Lexar have spent 2026 racing to fill shelves with Switch 2-branded cards, and why Nintendo’s own online store sells two of them directly under its own product listings.
It also explains a pattern reviewers have noted repeatedly through 2026: almost every microSD Express card on the market today is explicitly marketed around the Switch 2, rather than as a general-purpose PC or camera accessory the way older SD Express cards were. Retail listings from SanDisk, Samsung, and Lexar all lead with Nintendo Switch 2 branding on the packaging itself, because right now the console is functionally the only mainstream device that requires the standard. Digital cameras and laptops with PCIe-capable SD slots exist, but the volume driving this entire product category in 2026 is Switch 2 owners, full stop.
SanDisk vs Samsung vs Lexar: Full Spec Comparison
Before getting into pricing, it helps to see how the three leading brands stack up on paper. SanDisk and Samsung’s P9 line both carry Nintendo’s official license, meaning they’re validated and sold through Nintendo’s own storefront alongside third-party retailers. Lexar’s Play Pro line is marketed specifically for Switch 2 and built to the Express spec, but it isn’t one of the two officially co-branded partners.
| Spec | SanDisk microSD Express | Samsung P9 Express | Lexar Play Pro Express |
|---|---|---|---|
| Capacities available (US) | 256GB, 512GB, 1TB | 256GB, 512GB | 256GB, 512GB, 1TB |
| Rated sequential read | Up to 880 MB/s | Up to 800 MB/s | Not prominently published |
| Rated sequential write (256GB/512GB) | Up to 650 MB/s | Up to 200 MB/s | Not prominently published |
| Rated sequential write (1TB) | Up to 800 MB/s (745 MB/s sustained min.) | N/A (no 1TB SKU) | Not prominently published |
| Interface | PCIe-based microSD Express | PCIe-based microSD Express | PCIe-based microSD Express |
| Nintendo official license | Yes | Yes | No (Express-compliant, Switch 2-marketed) |
| Price, 256GB | $74.99 | $54.99 | $79.99 |
| Price, 512GB | $149.99 | $99.99 | $109.99 |
| Price, 1TB | $429 MSRP ($359 on sale) | Not sold | $349.99 |
| Measured write speed on Switch 2 hardware | 81.00-89.17 MB/s (Tom’s Hardware test) | Not independently benchmarked in sources reviewed | Not independently benchmarked in sources reviewed |
| Measured read speed on Switch 2 hardware | 110.93-112.29 MB/s (Tom’s Hardware test) | Not independently benchmarked in sources reviewed | Not independently benchmarked in sources reviewed |
| Best for | Buyers who want the widest capacity range and the Nintendo-store guarantee | Buyers who want the lowest price at a given capacity | Buyers who want a 1TB option cheaper than SanDisk’s |
Two things jump out immediately. First, Samsung’s P9 line tops out at 512GB in the US market as of August 2026, with no 1TB SKU showing up in retailer or press coverage, so anyone who wants a full terabyte has to look at SanDisk, Lexar, or a smaller third-party brand. Second, the rated write speed gap between SanDisk (up to 650-800 MB/s) and Samsung (200 MB/s, per Tom’s Hardware’s reporting on the P9) is large enough on paper to matter for anyone who records a lot of Switch 2 gameplay footage, even before real-world testing narrows that gap considerably.
Warranty coverage is another quiet differentiator that rarely makes it into headline comparisons. SanDisk and Samsung both back their Switch 2 cards with standard limited warranties typical of their broader memory card lineups, and because both carry Nintendo’s license, support disputes are less likely to hinge on whether the card was “approved” for the console in the first place. Lexar’s Play Pro line carries its own manufacturer warranty as well, though buyers occasionally report needing to go through Lexar directly rather than Nintendo for support, since it isn’t one of the two co-branded partners.
Pricing Breakdown: What Each Brand Actually Costs Right Now
Street pricing for Switch 2 storage has moved constantly through 2026 as retailers run flash sales against a backdrop of rising NAND and DRAM costs across the whole memory industry. The table below reflects standard (non-flash-sale) US pricing reported by Tom’s Hardware and 9to5Toys in August 2026, plus two notable third-party alternatives.
| Card | 256GB | 512GB | 1TB |
|---|---|---|---|
| SanDisk microSD Express for Switch 2 | $74.99 | $149.99 | $429 ($359 on sale) |
| Samsung P9 Express | $54.99 | $99.99 | Not available |
| Lexar Play Pro Express | $79.99 ($99.99 list) | $109.99 ($149.99 list) | $349.99 |
| TeamGroup Apex SD7.1 | Not confirmed | Not confirmed | $209.99 |
| PNY microSD Express | Not widely listed as of Aug 2026 | Not widely listed as of Aug 2026 | Not widely listed as of Aug 2026 |
At the 512GB tier, the gap that matters most to most buyers, Samsung’s P9 undercuts SanDisk’s official card by exactly $50, or roughly 33% cheaper for what is, on paper, a very similar product wearing the same Nintendo license. Lexar splits the difference at $109.99. That $50 spread on a single capacity tier is the single biggest reason price-sensitive Switch 2 owners are turning to Samsung first and asking questions about SanDisk’s premium later.
Licensing costs money in this market. In Japan, Nintendo’s own online store raised the price of its officially licensed SanDisk and Samsung microSD Express cards from ¥6,980 to ¥8,980 in mid-August 2026, a jump of roughly 28.7%, according to reporting from Impress Watch and ITmedia. That increase tracks with the broader 2026 memory-chip supply crunch that has also pushed up prices for gaming GPUs, DDR5 RAM kits, and internal SSDs across the industry this year, and it’s a strong signal that “official” pricing on either side of the Pacific is unlikely to fall soon.
Deal pricing adds another layer of noise worth flagging. SanDisk’s 512GB card has been reported by Tom’s Hardware at both its $149.99 standard price and as low as roughly $78 during limited flash sales, a swing of nearly 48%. Lexar’s cards move similarly: the 256GB Play Pro has been seen at both $99.99 list and $79.99 on sale, and the 512GB at $149.99 list versus $109.99 on sale. None of these discounts appear to be permanent price cuts, so the numbers in the tables above should be read as a realistic August 2026 snapshot rather than a guarantee of what you’ll pay on any given day. If you’re not in a rush, watching deal-tracking coverage from Tom’s Hardware, 9to5Toys, or IGN’s deals desk for a week or two before buying can meaningfully change which brand looks like the best value.
The 2026 Memory Crunch: Why Every Card Costs More Than Last Year
MicroSD Express pricing for Switch 2 doesn’t exist in a vacuum. Nearly every category of computer memory has gotten more expensive through 2026, driven largely by AI data center demand pulling NAND flash and DRAM production capacity away from consumer products. Gaming GPU prices, DDR5 RAM kits, and internal PC SSDs have all seen documented price increases this year for essentially the same underlying reason, part of the broader shift in AI chip and memory demand reshaping hardware pricing across the industry: fabs are prioritizing the memory chips that go into AI servers over the ones that go into a $75 memory card.
That context matters for anyone hoping prices will simply drop once the initial post-launch rush of Switch 2 buyers settles down. In a normal console generation, accessory prices for a maturing product tend to ease as manufacturing scales and competition increases. In 2026, that usual pattern is fighting against a genuine supply-side shortage that has nothing to do with Switch 2 specifically. The Japanese Nintendo Store’s 28.7% price hike on officially licensed cards in mid-August 2026 lines up with that broader trend rather than looking like an isolated Nintendo decision, and it’s one more reason to treat any current sale price as an opportunity rather than something to wait out for a better deal later.
For budget planning purposes, that means locking in a purchase when a card you want drops to a fair price, rather than assuming next month will be cheaper. The memory market’s direction through the second half of 2026 has consistently pointed toward tighter supply and higher prices, not the reverse.
How This Compares to Steam Deck and Other Handhelds’ Storage Needs
It’s worth putting the Switch 2’s microSD Express requirement in context against how rival gaming handhelds handle storage expansion, because the contrast is stark. The Steam Deck, in both its LCD and OLED versions, still uses standard UHS-I microSD cards for expanded storage, the same category Nintendo just locked out of the Switch 2 entirely. That means a Steam Deck owner can buy a well-reviewed 1TB UHS-I card for well under $100 and get perfectly serviceable performance, since Valve’s console was never designed around a PCIe-class card interface in the first place.
That difference isn’t a knock on either approach so much as a reflection of different design priorities. Valve’s handheld leans on its internal NVMe SSD for anything performance-sensitive and treats the microSD slot as bulk, secondary storage where UHS-I’s slower ceiling is an acceptable tradeoff for cost. Nintendo, by contrast, appears to be trying to make the expansion slot behave more like a genuine extension of the console’s internal 256GB UFS 3.1 storage, which is why it mandated a PCIe-based standard instead. The result, based on the Tom’s Hardware benchmark data covered earlier, is a card that costs two to four times more than an equivalent-capacity Steam Deck card while only delivering roughly double the real-world sustained throughput in practice, at least on the cards tested so far.
For anyone weighing a Switch 2 purchase against a Steam Deck, PS5, or other handheld, the honest takeaway is that Switch 2 ownership carries a genuine, unavoidable additional cost that other platforms in this generation don’t impose to the same degree, and it’s worth budgeting for that up front rather than discovering it after unboxing the console.
How Fast Are They Really? Benchmark Results From Tom’s Hardware
Manufacturer-rated speeds describe the ceiling of what a card’s controller and NAND can theoretically produce under ideal lab conditions. They rarely describe what happens when that same card is plugged into a Switch 2 and asked to load an actual game. Tom’s Hardware ran its own testing directly on Switch 2 hardware, using a 10-game load-time benchmark suite alongside raw file-transfer measurements, and the results show a substantial gap between marketing numbers and real-world throughput.
| Card | Measured write (“to card”) | Measured read (“from card”) | 10-game average load time |
|---|---|---|---|
| SanDisk microSD Express 256GB | 81.00 MB/s | 112.29 MB/s | 410.8 seconds |
| SanDisk microSD Express 512GB | 89.17 MB/s | 110.93 MB/s | 479.1 seconds |
SanDisk advertises up to 880 MB/s of sequential read on the box. Tom’s Hardware measured 110-112 MB/s in practice on real Switch 2 hardware, roughly an eighth of the rated figure. Write performance told the same story: SanDisk claims up to 650 MB/s for its 256GB and 512GB cards, but the actual measured write speed came in at 81-89 MB/s. That’s not a defect specific to SanDisk’s card; it reflects how the Switch 2’s own controller, firmware, and file-system overhead throttle throughput well below what the microSD Express interface can theoretically sustain, similar to how a fast NVMe drive rarely hits its rated speed once it’s behind a slower host controller.
One counterintuitive detail from the same test set: the 512GB card posted a slightly slower average load time (479.1 seconds across the 10-game suite) than the 256GB card (410.8 seconds), despite similar raw transfer speeds. That’s likely down to differences in which games and save files landed on each test unit rather than any inherent capacity-based slowdown, but it’s a useful reminder that headline MB/s figures don’t always translate cleanly into “faster game loading” on a specific device.
Neither Samsung’s P9 nor Lexar’s Play Pro has an equivalent, independently published Switch 2 hardware benchmark in the sources reviewed for this piece as of late August 2026. Buyers choosing between brands on raw speed alone should treat that as a genuine information gap rather than assume parity, though the SanDisk data at least establishes a realistic ceiling: no microSD Express card is likely to blow past roughly 110-115 MB/s of real, sustained throughput on this specific console, regardless of what the packaging claims.
Rated Speeds vs Real-World Performance: The Gap Explained
It’s worth spending a moment on why this gap exists, because it changes how you should shop. Rated speeds on a microSD Express card describe the card’s own controller talking to a PCIe-capable host under laboratory conditions, often using a dedicated card reader rather than a consumer device. The Switch 2’s own storage controller, its firmware overhead, thermal constraints inside a compact handheld chassis, and the specific way game data is chunked and accessed all sit between that theoretical number and what you experience at the console.
This matters most for two groups of buyers: people who care about install and load times, and people who record 4K gameplay clips directly to the card. For load times, the Tom’s Hardware data suggests the difference between SanDisk’s most expensive card and Samsung’s cheapest one is likely to be small in practice, since both are ultimately bottlenecked by the same console-side ceiling. For 4K capture, sustained write speed still matters more, and SanDisk’s higher rated write ceiling (up to 800 MB/s on the 1TB card versus Samsung’s 200 MB/s rating) is more likely to show a real difference during long recording sessions, even if neither card reaches those numbers on the Switch 2 itself.
PNY, TeamGroup, and Other Alternatives Worth a Look
SanDisk, Samsung, and Lexar aren’t the only companies making Switch 2-compatible microSD Express cards, though they’re the three with the clearest US retail presence and pricing history through 2026.
PNY entered the category with a microSD Express card rated at up to 890 MB/s read and up to 750 MB/s write, according to Tom’s Hardware’s coverage of the launch, figures that would technically edge out even SanDisk’s rated ceiling. PNY’s own product page lists a similar spec sheet. The catch is availability: as of August 2026, PNY’s Switch 2 card hadn’t shown up with consistent US retail pricing across the major outlets tracked for this comparison, making it harder to recommend confidently until it’s more widely stocked and reviewed.
TeamGroup’s Apex SD7.1 line is worth flagging for one specific reason: at 1TB, it’s listed at $209.99, which undercuts SanDisk’s $429 MSRP by more than half and comes in well below Lexar’s $349.99 for the same capacity. For anyone whose priority is maximum storage at the lowest dollar-per-gigabyte, TeamGroup’s 1TB option deserves a look even though it carries less brand recognition and no Nintendo license.
Neither PNY nor TeamGroup has the same volume of independent Switch 2 benchmark coverage as SanDisk, so treat their rated specs as manufacturer claims rather than console-verified performance, exactly the same caveat that applies to Samsung and Lexar above.
Can You Still Use Your Old Switch’s MicroSD Card?
This is the single most common question new Switch 2 owners ask, and Nintendo’s own support documentation answers it without ambiguity. A standard UHS-I microSD card, including any expensive high-capacity card bought for an original Switch or Switch OLED, is marked “Cannot be used” in Nintendo’s official compatibility table for Switch 2. It isn’t a matter of reduced performance or a fallback mode limited to screenshots. According to Nintendo’s FAQ, only cards that meet the microSD Express standard can be used to save game data, in-game screenshots, or videos on Switch 2.
Practically, that means the microSD card slot on your original Switch and the one on your Switch 2 are compatible in form factor only. You can physically insert an old card into the new console, but the system will not recognize it as usable storage for anything. Anyone upgrading needs to budget for a new card as part of the transition, on top of the console itself, whose own MSRP is set to rise from $449.99 to $499.99 starting September 1, 2026, according to Nintendo of America’s own announcement.
How to Migrate Your Data to a New MicroSD Express Card
Because Switch 2 won’t read data off an old UHS-I card at all, there’s no simple drag-and-drop file transfer between an original Switch’s microSD card and a new Express card. For a full walkthrough of inserting and formatting a new card, see our step-by-step guide to expanding Switch 2 storage. Here’s the realistic path most owners will follow for moving their actual data over:
- Back up save data for any games that support Nintendo Switch Online’s cloud save feature before you set up the new console, since local save files on an incompatible card can’t be pulled across directly.
- Use Nintendo’s console-to-console System Transfer process to move your user profile, digital game licenses, and eligible save data from the original Switch to the Switch 2 over a network connection, rather than via the memory card.
- Insert your new microSD Express card into the Switch 2 before or immediately after the transfer completes, so downloaded games have somewhere to install.
- Re-download digital titles from the eShop as needed; digital licenses tied to your Nintendo Account follow you through the transfer, but the actual game files have to be reinstalled onto the new card.
- For games without cloud save support, check each title’s in-game or system-level save management options, since coverage varies by publisher and not every game supports the cloud save feature.
- Keep the old microSD card and original Switch around until you’ve confirmed every save file and game you care about has successfully carried over, rather than wiping or reformatting the old card immediately.
The bottom line: budget both the time and the new card into your upgrade plan. This isn’t a five-minute card swap the way it was moving from an 128GB card to a 512GB card on the same console generation.
Real-World Scenarios: Which Card Fits Your Situation
The digital-only library builder
If you buy almost everything digitally and your Switch 2 library is going to grow past a dozen large titles, capacity matters more than brand prestige. TeamGroup’s Apex SD7.1 1TB at $209.99 or Lexar’s Play Pro 1TB at $349.99 both undercut SanDisk’s $429 1TB card meaningfully, and given that real-world throughput converges around the same 100-115 MB/s ceiling regardless of brand, the extra $220 for SanDisk’s 1TB card is hard to justify on performance grounds alone.
The budget-conscious single-console household
For someone who just wants enough room for four or five modern games at a time, Samsung’s P9 256GB at $54.99 is the cheapest confirmed entry point among the officially licensed cards, undercutting SanDisk’s 256GB by exactly $20.
The family console with shared profiles
Multiple user profiles sharing one Switch 2 tend to outgrow 256GB quickly. Samsung’s P9 512GB at $99.99 is $50 cheaper than SanDisk’s equivalent capacity and gives enough headroom for several profiles’ worth of installed games without jumping straight to a 1TB purchase.
The gameplay capture and streaming enthusiast
Anyone recording extended 4K gameplay clips should lean toward SanDisk’s higher rated write ceiling (up to 800 MB/s on the 1TB card, versus Samsung’s 200 MB/s rating), even accounting for the fact that neither card will hit those numbers inside the Switch 2 itself. Sustained write headroom still tends to matter more for long recording sessions than for game installs.
The physical-cartridge collector
If most of your library sits on cartridges and the card is mainly there for screenshots, video captures, and the occasional digital patch or DLC, a 256GB card from Samsung or Lexar is plenty, and there’s little reason to pay for 512GB or 1TB of unused headroom.
The upgrader coming from an original Switch
Remember that your old card, no matter how large or expensive, will not carry over. Match your new Express card’s capacity to your actual current library size rather than assuming you need to replicate whatever capacity you had before, since Switch 2 games and updates tend to run larger than original Switch titles.
Pros and Cons: SanDisk vs Samsung vs Lexar
SanDisk microSD Express
- Pro: Widest capacity range, including the only tested 1TB option with published benchmark data
- Pro: Highest rated write speed ceiling (up to 800 MB/s on 1TB), useful for gameplay capture
- Pro: Officially Nintendo-licensed and sold through Nintendo’s own store
- Con: Most expensive at every matching capacity tier among the three main brands
- Con: Real-world Tom’s Hardware benchmarks show actual write speeds of just 81-89 MB/s, far below the rated 650-800 MB/s
Samsung P9 Express
- Pro: Cheapest officially licensed option at both 256GB ($54.99) and 512GB ($99.99)
- Pro: Also carries Nintendo’s official license

- Con: Lower rated write speed (200 MB/s) than SanDisk’s published figures
Lexar Play Pro Express
- Pro: Only brand offering competitively priced options across 256GB, 512GB, and 1TB
- Pro: 1TB card at $349.99 is meaningfully cheaper than SanDisk’s $429 MSRP
- Con: Not one of Nintendo’s two officially licensed card partners
- Con: Rated speed specs are less prominently published than SanDisk’s or Samsung’s, making direct comparison harder
Why Official Nintendo-Licensed Cards Cost More
SanDisk and Samsung’s Express cards both carry Nintendo’s official license and branding, sold directly through Nintendo’s own storefront in addition to standard retail channels. That licensing relationship isn’t free for the manufacturer, and it shows up in pricing dynamics: the same Japanese Nintendo Store price hike from ¥6,980 to ¥8,980 in mid-August 2026 applied to both of the officially licensed cards, not to third-party options like Lexar or TeamGroup.
For most buyers, the practical benefit of buying a licensed card is confidence rather than performance. Both are validated to work reliably with Switch 2’s storage controller and firmware, and Nintendo’s own support channels will troubleshoot them without pointing to third-party compatibility as a possible cause. Whether that assurance is worth a $20 to $50 premium over Lexar or a similarly specced third-party card is ultimately a personal risk tolerance question, not a performance one, since the Tom’s Hardware benchmark data suggests the console itself is the bottleneck regardless of which brand’s Express card you buy.
Capacity Planning: How Much Storage Do You Actually Need
Switch 2’s 256GB of built-in UFS 3.1 storage sounds generous next to the original Switch’s 32GB, but a portion is reserved for system use, and Switch 2-native titles tend to run considerably larger than their original Switch counterparts thanks to higher-resolution textures and 4K-capable output. A single AAA-scale Switch 2 game plus day-one patches can already consume a meaningful slice of that internal 256GB.
As a rough guide: a 256GB Express card roughly doubles your total usable space and suits players with three to six actively installed titles at a time. A 512GB card is the sweet spot for households with multiple user profiles or anyone who doesn’t want to regularly delete and redownload games. A 1TB card mostly makes sense for digital-only collectors who install everything they own and rarely uninstall anything, especially now that TeamGroup and Lexar both offer that capacity well under SanDisk’s $429 price point.
It’s also worth thinking about capacity in terms of cost per gigabyte rather than just the sticker price, since the two don’t move together across brands. Samsung’s 512GB card works out to roughly $0.20 per GB, while SanDisk’s 512GB card runs closer to $0.29 per GB, a meaningful gap once you’re shopping for a card you might keep for the console’s entire lifespan. At 1TB, Lexar’s $349.99 card and TeamGroup’s $209.99 card both undercut SanDisk’s per-gigabyte cost by a wide margin, which is exactly why capacity-focused buyers keep gravitating toward those two options over the official SanDisk card despite its wider name recognition.
One more planning wrinkle: because game installs, day-one patches, and downloadable content all eat into whatever capacity you buy, it’s generally smarter to round up to the next tier rather than buy exactly what your current library needs. A card that’s 80% full within the first few months of ownership is a common complaint in Switch 2 owner communities, and swapping to a larger card later means going through the same System Transfer and re-download process described above a second time.
The Verdict: Which MicroSD Express Card Should You Buy
Based on current August 2026 pricing and the available benchmark data, there isn’t a single universal winner, but there is a clear default recommendation for most buyers. Samsung’s P9 Express delivers the best value at both 256GB ($54.99) and 512GB ($99.99), undercutting SanDisk’s officially licensed equivalent by $20 to $50 per capacity while carrying the same Nintendo license and, per Tom’s Hardware’s real-world benchmark data on similarly specced cards, facing the same console-side performance ceiling regardless of brand.
SanDisk earns its premium only for buyers who specifically need a 1TB card with independently verified Switch 2 benchmark data, or who prioritize the higher rated write ceiling for gameplay capture over saving money. Lexar’s Play Pro line is the pragmatic middle ground for anyone who wants a 1TB option without paying SanDisk’s $429, and TeamGroup’s $209.99 1TB card is the one to check out if raw capacity per dollar is the only thing that matters.
What all three main brands share is the same hard ceiling: Tom’s Hardware’s testing shows real Switch 2 hardware caps out around 110-115 MB/s of read throughput no matter which card is inserted, so the rated speed war on the packaging matters far less than the price tag once you’re actually loading a game.
If you’re still undecided, the simplest framework is this: pick your capacity first based on how you actually play (digital-only versus cartridge collector, single user versus shared household), then pick the cheapest brand at that specific capacity that carries either Nintendo’s official license or a reputation for reliable Switch 2 compatibility. Right now, that path leads most buyers to Samsung at 256GB or 512GB, and to Lexar or TeamGroup at 1TB, with SanDisk reserved for buyers who specifically want the most independently verified card on the market and are willing to pay a premium for that certainty.
Frequently Asked Questions
Can I use my old Nintendo Switch’s microSD card in a Switch 2?
No. Nintendo’s official compatibility documentation states that a standard microSD card previously used on a Switch console cannot save or load digital games or save data when inserted into a Switch 2. Only cards meeting the microSD Express standard work for game storage.
What exactly is microSD Express and how is it different from regular microSD?
microSD Express is a newer SD Association standard that adds a PCIe-based interface to the microSD form factor, enabling theoretical sequential speeds in the 800-900 MB/s range, far beyond the roughly 104 MB/s ceiling of the UHS-I standard used by the original Switch.
What’s the maximum capacity microSD Express card the Switch 2 supports?
Up to 2TB, according to Nintendo’s official microSD Express FAQ, though no 2TB consumer card was confirmed as widely available from major brands as of August 2026.
Do I need a Nintendo-licensed card, or will any microSD Express card work?
Any card meeting the microSD Express standard should work, but only SanDisk and Samsung currently carry Nintendo’s official license and are sold through Nintendo’s own store. Third-party options like Lexar, TeamGroup, and PNY are marketed as Switch 2-compatible without that official branding.
Why don’t rated speeds match real-world benchmark results?
Rated speeds describe a card’s theoretical maximum under lab conditions, often via a dedicated PCIe card reader. Tom’s Hardware’s testing on actual Switch 2 hardware found SanDisk’s cards, rated up to 880 MB/s read, actually delivering 110-112 MB/s in practice, because the console’s own controller and firmware become the bottleneck.
Is Samsung’s P9 as good as SanDisk’s card despite costing less?
For most buyers, yes. Given that real-world throughput on Switch 2 hardware appears to be limited by the console rather than the card, Samsung’s lower price at 256GB and 512GB makes it the stronger value pick unless you specifically need SanDisk’s 1TB capacity or its higher rated write ceiling for video capture.
How much internal storage does the Switch 2 have, and do I need a card right away?
The Switch 2 ships with 256GB of internal UFS 3.1 storage. Whether you need a card immediately depends on your library size, but anyone planning to own more than a handful of modern digital titles will likely want to budget for an Express card from day one.
