Most microSD playing cards are quick sufficient for stashing images, recording video and transferring information, however some will get you somewhat extra bang on your buck than others. In the event you’re seeking to increase the interior storage of your Nintendo Switch, Steam Deck, GoPro, Raspberry Pi or another system that also has compatibility with microSD playing cards, we may also help. We’ve completely researched the market and put greater than a dozen microSD playing cards by way of a variety of benchmark checks: Listed below are the most effective that we’ve examined, together with some basic recommendation on what to search for when shopping for a brand new card.
Editor’s notice (4/24/24): Samsung has launched an upgraded version of our “greatest worth” decide, the Evo Choose. We plan to check it quickly and replace our information accordingly. Samsung says the brand new mannequin can attain sequential learn speeds as much as 160 MB/s, so it ought to nonetheless be a step down from our different high picks, which we proceed to advocate
What to search for in a microSD card
Capability
The very first thing to determine when shopping for a microSD card is how a lot area you want. Fashionable playing cards are often accessible in sizes starting from 32GB to 512GB, whereas a handful provide 1TB fashions as nicely. 2TB playing cards are theoretically doable however still in the prototype stage.
For many, a 128GB or 256GB mannequin needs to be the candy spot between value and space for storing. However if you happen to want extra room — say, for stashing a bunch of video games on a Steam Deck — a 512GB card might make extra sense and sometimes gives a greater cost-per-GB ratio. Lately, you could find a good 128GB card for round $15 or much less, an excellent 256GB card for lower than $30 and a strong 512GB card for lower than $40 (although many price nearer to $50 or $60). There’s a starker enhance whenever you go as much as 1TB playing cards, which generally price nearer to $100.
Word {that a} microSD card’s efficiency might differ relying on what capability you purchase. SanDisk says its 128GB Extreme card delivers sequential write speeds as much as 90 MB/s, for instance, whereas the higher-capacity fashions in the identical line provide as much as 130 MB/s.
After we discuss microSD playing cards immediately, we often seek advice from playing cards that use the microSDXC (eXtended Capacity) standard, which have a capability between 32GB and 2TB. Your system must help this for it to work with a microSDXC card. This can virtually by no means be a problem today, however some older gadgets (a Nintendo 3DS, as an example) are solely suitable with microSDHC (Excessive Capability) playing cards, which vary from 2GB to 32GB.
Learn and write speeds
MicroSD playing cards are primarily judged on their learn and write speeds, that are often measured in megabytes per second (MB/s). Usually, most microSD playing cards have sooner learn speeds than write speeds.
These metrics can then be damaged down into sequential and random efficiency. Sequential learn and write speeds matter whenever you’re making an attempt to entry or save lengthy, fixed streams of knowledge, reminiscent of opening a big video or copying a giant batch of information from a PC. If you wish to use a microSD card for media storage, that is notably essential. Random efficiency, in the meantime, is about how rapidly a card can learn and write small information scattered all through the system.
Since random learn/write speeds are a lot decrease than sequential ones, storage system makers have a tendency to not promote them as loudly. However they’re essential if you happen to use a card with a gaming system or a single-board pc just like the Raspberry Pi, the place it usually has to quickly save and entry small bits of knowledge in random areas.
Velocity rankings
In the event you take a look at a microSD card, you’ll see a buffet of numbers, letters and symbols. Most of those seek advice from the cardboard’s speed class and efficiency rankings, that are decided by the SD Association.
A card’s Video Velocity Class, or V-rating, particulars its minimal sequential write pace, which is particularly essential when recording video from a digicam. It ranges from V6 to V90. Many of the playing cards we examined had a V30 score, in order that they have a sequential write pace of a minimum of 30 MB/s. This needs to be sufficient to help as much as 4K video at decrease bitrates. Increased-rated V60 and V90 playing cards are often higher for capturing 8K, however they arrive at a a lot greater price.
The UHS Velocity Class, or U-rating, additionally refers to a card’s minimal sequential write pace. It is available in two varieties: U3, which mandates a minimal of 30 MB/s, and U1, which is rated for 10 MB/s.
The older Velocity Class score overlaps with the opposite two methods. It’s signified by a C image and goes from Class 2 to Class 10, with the quantity (once more) indicating minimal sequential write pace. This score is much less related these days, however you should still see a “C10” brand on some playing cards.
The Utility Efficiency spec, marked by an An emblem, is an indicator of random learn/write speeds. That is measured in IOPS, or enter/output operations per second, relatively than MB/s. There are two classes right here: A1 playing cards provide a minimal random learn pace of 1,500 IOPS and a minimal random write pace of 500 IOPS, whereas A2 playing cards bump these as much as 4,000 IOPS and a pair of,000 IOPS, respectively. Each rankings additionally assure sequential write speeds of a minimum of 10 MB/s.
To maintain it easy, most individuals ought to search for a card with V30, U3 and A2 rankings. It’s completely doable to get a strong card with out these: A U1 card is likely to be price it if you happen to simply want an affordable, high-capacity choice, for instance. V60 and V90 playing cards are price a glance if you happen to’re severe about capturing high-resolution images and video as nicely. However general, playing cards with the certifications above ought to present the most effective mix of value and efficiency immediately.
It’s essential to emphasise that these rankings are baselines. Most V30 playing cards provide considerably greater write speeds than 30 MB/s, as an example, and a few A1 playing cards can outperform some A2 fashions in apply. The speeds marketed by producers aren’t all the time one hundred pc correct, both: Typically the cardboard shall be slower in real-world use, different occasions it might truly be a bit sooner.
UHS bus speeds
The opposite spec to notice is the cardboard’s bus interface. Most microSD playing cards accessible immediately are UHS-I, which have a theoretical most pace of 104 MB/s. There are additionally UHS-II playing cards, which have an additional row of pins on the again and may attain as much as 312 MB/s. (A UHS-III commonplace exists as nicely however hasn’t seen broad adoption.) These are labeled on the cardboard with a Roman numeral I or II.
The quickest microSD playing cards you should buy proper now are UHS-II playing cards, and so they’re often those with V60 or V90 rankings. In the event you shoot plenty of 4K to 8K video or incessantly use burst mode to seize extremely high-res images, the efficiency positive aspects of an excellent UHS-II card can prevent time.
However these are rather more costly than UHS-I playing cards: As an example, this 128GB model from Lexar is a good discount at $40. That’s lower than many UHS-II fashions we’ve seen up to now however nonetheless greater than double the standard value of our high decide talked about under. You want a tool that’s suitable with the UHS-II interface to see any advantages, too, and inventory for UHS-II playing cards is mostly spottier. For now, the upper speeds aren’t well worth the value premium for most individuals, so we caught largely to UHS-I playing cards right here.
We’ll additionally notice Samsung’s recent announcement of a brand new 256GB microSD card based mostly on a wholly totally different commonplace known as SD Categorical. That is theoretically a lot sooner than any UHS-I or UHS-II choice: Samsung claims this particular mannequin can attain sequential learn speeds as much as a whopping 800 MB/s. For context, that’d be faster than some older SSDs. SD Categorical has technically been around for a number of years however hasn’t seen broad adoption, so precisely how this card performs in actuality — and the way a lot it’ll price — stays to be seen. We’ll check the system as soon as it turns into accessible, which Samsung says shall be someday later in 2024.
A notice on card readers, the Nintendo Change and Steam Deck
Whereas the UHS-I spec has a theoretical most of 104 MB/s, some UHS-I playing cards can exceed that pace by way of proprietary extensions. You want a suitable card reader and host system to reap the benefits of that additional efficiency, although. In the event you discover a UHS-I card promoting speeds greater than 104 MB/s, that is what’s happening. You possibly can see these limits in motion with a Nintendo Change or Steam Deck: Both of those gaming gadgets help the UHS-I interface and don’t transcend its official pace, flattening any sequential positive aspects some playing cards might have elsewhere. The broader takeaway: Your microSD card will solely be as quick because the slowest hyperlink in your chain.
Guarantee
Many microSD playing cards are designed to be sturdy, with safety from water, excessive temperatures, X-rays and drops. Nonetheless, in case of disaster, an extended guarantee is all the time good to have. Many producers provide lifetime restricted warranties, although we’ve seen that “endurance” playing cards marketed to face up to extra hours of writing are often lined for a a lot shorter time period.
Avoiding counterfeits
The reminiscence card market has had a specific downside with scammers promoting pretend merchandise. To protect towards this, solely purchase from a identified model and a good retailer reminiscent of Finest Purchase, B&H Photograph or Adorama. In the event you store at Amazon, solely purchase if the shipper and vendor is Amazon.com. (Although a handful of customers have reported receiving counterfeits even from Amazon instantly up to now.) Keep in mind: If a value appears too good to be true, it most likely is. Be cautious of any retailer providing considerably a lower cost than others.
When you obtain a card, verify its packaging for any irregularities. You possibly can run benchmark checks like CrystalDiskMark or BlackMagic Disk Speed Test to confirm its speeds aren’t drastically decrease than what’s marketed (or doable, given its specs). You too can use software program that’s designed to confirm the true capability and efficiency of your card, reminiscent of H2testw and FakeFlashTest.
How we examined
We put 13 microSD playing cards by way of a collection of checks to confirm their sequential and random efficiency. These included benchmarks like CrystalDiskMark, BlackMagic Disk Speed Test, ATTO Disk Benchmark and AJA System Test, in addition to a couple of “real-world” checks. We copied and pasted a small folder of images about 1.15GB in dimension to and from every card, then did the identical with a bigger 12.2GB folder containing a number of file sorts and subfolders, timing the method every time. We additionally checked how every card carried out on the Steam Deck, downloading video games of various sizes — together with Stardew Valley, Aperture Desk Job, Metal Gear Rising: Revengeance and Apex Legends — then timing how lengthy it took to launch every recreation and cargo save information.
We used a Kingston USB 3.2 UHS-II reader to check every card on each Home windows 11 and macOS Sonoma. For the previous, we used an Alienware gaming PC with an Intel Core i9-10900F, Nvidia GeForce RTX 3080 GPU, 32GB of RAM and a 1TB SSD. For the latter, we used a 2021 16-inch MacBook Professional with an Apple M1 Professional chip, 16GB of RAM and a 512GB SSD. To make use of our card reader on the MacBook, we used Apple’s USB-C Digital AV Multiport Adapter.
We examined the 128GB model of every card wherever doable, although for a couple of playing cards — SanDisk’s Excessive and Samsung’s Professional Plus and Professional Final — we have been solely capable of check their 256GB fashions. We additionally reformatted every card earlier than testing with the SD Affiliation’s Memory Card Formatter tool.

Storage capability: 128GB, 256GB, 512GB | Velocity lessons: U3, V30, A2, Class 10 | Guarantee: 10-year restricted
The Samsung Pro Plus was practically the quickest card we examined when it comes to sequential write efficiency (round 130 MB/s in CrystalDiskMark) and was a detailed second when it comes to random learn/write speeds, so it ought to work nice whether or not you’re shopping for for a digicam, pill or gaming handheld. Unsurprisingly, it has all of the requisite rankings: U3, V30 and A2. Its sequential learn efficiency (round 165 MB/s) isn’t fairly as fast as a few of the different playing cards under, so it isn’t absolutely the quickest for accessing massive information saved in your card, however the distinction is small in real-world use.
The primary motive the Professional Plus tops our checklist is as a result of it delivers these sturdy speeds at a comparatively reasonably priced value. The cardboard initially began at $19 for 128GB, $30 for 256GB and $60 for 512GB, however latest gross sales have introduced these fashions as little as $11, $18 and $29, respectively. When it’s that low-cost, the Professional Plus makes most competing microSD playing cards redundant. Samsung additionally sells the cardboard with a USB reader that’ll assist it attain its most speeds for a couple of {dollars} extra. Both approach, the cardboard comes with a 10-year restricted guarantee.
In the event you decide to purchase the Professional Plus, be sure to get the latest-generation mannequin. Samsung continues to be promoting the prior iteration of the Professional Plus, which seems equivalent however isn’t as fast. As an alternative, go for the one with sequential learn speeds rated at 180 MB/s and sequential write speeds rated at 130 MB/s. We examined the 256GB model of the newer Professional Plus because of inventory points with the 128GB mannequin on the time of testing, however this shouldn’t have a serious influence on real-world efficiency, as Samsung charges each playing cards identically. Proper now the cardboard is obtainable as much as 512GB, however the firm it’ll launch a 1TB mannequin later in 2024.
- Persistently fast sequential and random learn/write efficiency
- Nice worth
- Simply accessible at trusted retailers
- Some friends have barely sooner sequential learn speeds
- No 1TB mannequin

The Samsung Pro Ultimate is a step-up mannequin in Samsung’s microSD lineup and, as anticipated, it’s somewhat bit sooner than the Professional Plus throughout the board. Its greatest positive aspects are in sequential learn speeds, which have been the quickest we examined and averaged near Samsung’s marketed price price of 200 MB/s throughout our numerous benchmarks. You’ll want to purchase the cardboard with Samsung’s USB reader to realize that efficiency, however that could possibly be price it if you happen to commonly transfer information out of your microSD card to a PC. The Professional Final technically led the pack when it got here to sequential write and random learn/write speeds as nicely, although the margins there are a lot much less important in comparison with the Professional Plus and the opposite high UHS-I playing cards we examined.
The primary query is price. In the event you see the Professional Final accessible for a similar value because the Professional Plus, you may as nicely seize it as an alternative. It comes with the identical 10-year guarantee and needs to be equally sturdy. Previous reductions have introduced the 128GB, 256GB and 512GB fashions as little as $15, $25 and $45, respectively; that is nonetheless reasonably priced, however the Professional Plus will virtually all the time be somewhat bit cheaper — and thus a greater worth for many wants, particularly at greater capacities.
- Quickest microSD card we examined (with applicable USB reader)
- Simply accessible at trusted retailers
- Professional Plus is best worth for many
- No 1TB mannequin

If the Samsung Professional Plus ever turns into unavailable, the Kingston Canvas Go Plus is one other sturdy various. It is a U3-, V30- and A2-rated card backed by a lifetime restricted guarantee. Its sequential learn speeds trailed solely the Samsung Professional Final throughout CrystalDiskMark, ATTO and the BlackMagic Disk Velocity Take a look at. It successfully tied with SanDisk’s Excessive and Nintendo Change-branded playing cards in our massive file switch speeds check. Its sequential write speeds (simply over 100 MB/s on CrystalDiskMark) are the place it lags behind the Professional Plus, however they need to nonetheless be fast sufficient for a lot of makes use of. Its random learn/write speeds have been solely bested by Samsung’s Professional playing cards in benchmarks, too, so it’s nonetheless an excellent choice for apps and video games. However it’s onerous to justify if you happen to see it priced greater than the Professional Plus or Final.
- Quicker sequential write speeds than Professional Plus for a (usually) lower cost than Professional Final
- Lifetime restricted guarantee
- Professional Plus is a greater worth for many
- Slower sequential write speeds than picks above
- No 1TB mannequin

The Samsung Evo Select is a transparent step behind our high picks, notably with regards to sequential write speeds (just below 70 MB/s on CrystalDiskMark), so it’s not superb for cameras. Nonetheless, it’s completely usable for a lot of use instances — a Nintendo Change, as an example — and we have beforehand seen its 128GB, 256GB and 512GB fashions fall as little as $10, $14 and $25, respectively. All of these are about on par with the SanDisk Ultra, a incessantly beneficial cheapo card, regardless of the Evo Choose having greater V30, U3 and A2 rankings. Whereas the Professional Plus has come near these costs, the Evo Choose tends to take a seat there extra commonly. The 512GB variant is a very nice discount if you happen to simply want a piece of area on a budget. (The Extremely is obtainable in 1TB and 1.5TB capacities, although.)
- Typically accessible for lower cost than Professional Plus
- Stable efficiency if you happen to simply need the most affordable acceptable card doable
- Slower than picks above, notably in sequential write and random efficiency benchmarks
- No 1TB mannequin
Different notable microSD playing cards
Delkin Gadgets Energy
We didn’t use it ourselves, however if you happen to’re prepared to pay for a extra highly effective UHS-II card constructed for heavy-duty video recording, the Delkin Devices Power has tested well elsewhere and may ship considerably sooner sequential write speeds than our picks above. It’s one of many few UHS-II playing cards we might truly discover in inventory, nevertheless it prices a ton, with a 128GB mannequin usually priced at $93.
SanDisk microSDXC Card for Nintendo Change
The SanDisk microSDXC Card for Nintendo Switch is one other respectable choice if you happen to ever see it accessible for lower than the Professional Plus and Canvas Go Plus. Its sequential learn speeds have been about the identical because the latter in our benchmarks, however its sequential writes have been barely slower (and farther behind the Professional Plus). Its random learn/writes have been a bit behind based on CrystalDiskMark as nicely. The 128GB version of this card is priced round $18 as of this writing, whereas the 512GB mannequin prices round $50; each are greater than the Professional Plus. SanDisk backs the cardboard with a lifetime guarantee, nevertheless, plus it’s accessible in a 1TB capacity. Word that we examined the Apex Legends model of the 128GB card; SanDisk additionally sells a Super Mario model, however we will’t communicate as to if that one performs any in a different way.
Lexar Skilled 1066x
Equally, the Lexar Professional 1066x is a good various to the Professional Plus if our important picks are unavailable. It’s one other V30, U3 and A2 mannequin, and like Samsung’s card, its sequential write speeds have been a bit sooner than the Canvas Go Plus and SanDisk Change card in our benchmarks. These write speeds weren’t as fast because the Professional Plus, and its sequential reads trailed all three playing cards. Random learn/writes additionally lagged behind the Professional Plus and Canvas Go Plus, and we seen its speeds peak and dip extra noticeably in our file switch check. Nonetheless, it’s not gradual, so relying on its value, it is likely to be an excellent discount if you happen to want quick write speeds for video recording and the like. It’s additionally available in 1TB, plus it comes with a lifetime restricted guarantee.
SanDisk Excessive
The SanDisk Extreme successfully matched the Professional Plus in a couple of of our sequential write checks and delivered sequential reads about on par with the Canvas Go Plus, however that was partly because of us solely having the ability to safe the cardboard’s 256GB mannequin, which is higher-rated than the 128GB model. It’s a high quality selection if you happen to see it on sale at a good vendor, however its random efficiency lagged behind the Samsung Professional and Kingston playing cards, and it usually prices extra. It does have a 1TB model, although.
SanDisk Excessive Professional
The SanDisk Extreme Pro is a rival to the Samsung Professional Final however, as of this writing, is both unavailable at most trusted retailers or priced too excessive by comparability.
PNY Elite-X
The PNY Elite-X wasn’t too far off the random learn/write efficiency of the Professional Plus and Professional Final in CrystalDiskMark, and it usually goes for reasonable, nevertheless it was nicely behind in our sequential checks.
