Most microSD playing cards are quick sufficient for stashing pictures, recording video and transferring information, however some will get you slightly extra bang in your buck than others. In the event you’re trying to increase the inner storage of your Nintendo Switch, Steam Deck, GoPro, Raspberry Pi or another system that also has compatibility with microSD playing cards, we might help. We’ve totally researched the market and put greater than a dozen microSD playing cards via a variety of benchmark checks: Listed below are the perfect that we’ve examined, together with some common recommendation on what to search for when shopping for a brand new card.
Editor’s observe (5/28/24): We’ve examined the most recent iteration of Samsung’s Evo Choose, however we expect the improve isn’t vital sufficient to make it price recommending to most people who simply desire a first rate microSD card for as little cash as attainable. We’ve famous the brand new mannequin in our information under. We additionally plan on testing Lexar’s new Professional Silver Plus card, which is ready to reach in June and guarantees barely higher speeds than our “quicker possibility” decide.
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 supply 1TB fashions as nicely. 2TB playing cards are theoretically attainable however still in the prototype stage.
For many, a 128GB or 256GB mannequin ought to be the candy spot between worth and space for storing. However in the event you want extra room — say, for stashing a bunch of video games on a Steam Deck — a 512GB card might make extra sense and infrequently gives a greater cost-per-GB ratio. Lately, yow will discover a good 128GB card for round $15 or much less, a great 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 while you go as much as 1TB playing cards, which usually price nearer to $100.
Observe {that a} microSD card’s efficiency could 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 supply 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 assist this for it to work with a microSDXC card. This may nearly by no means be a difficulty nowadays, however some older gadgets (a Nintendo 3DS, as an illustration) 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 quicker learn speeds than write speeds.
These metrics can then be damaged down into sequential and random efficiency. Sequential learn and write speeds matter while you’re making an attempt to entry or save lengthy, fixed streams of knowledge, equivalent to 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 necessary. Random efficiency, in the meantime, is about how shortly 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 necessary in the event you use a card with a gaming system or a single-board laptop just like the Raspberry Pi, the place it usually has to quickly save and entry small bits of knowledge in random areas.
Velocity scores
In the event you have 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 scores, that are decided by the SD Association.
A card’s Video Velocity Class, or V-rating, particulars its minimal sequential write pace, which is very necessary when recording video from a digicam. It ranges from V6 to V90. A lot of the playing cards we examined had a V30 ranking, so that they have a sequential write pace of a minimum of 30 MB/s. This ought to be sufficient to assist as much as 4K video at decrease bitrates. Greater-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 ranking overlaps with the opposite two programs. 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 ranking 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 A logo, is an indicator of random learn/write speeds. That is measured in IOPS, or enter/output operations per second, fairly than MB/s. There are two classes right here: A1 playing cards supply 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 scores 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 scores. It’s completely attainable to get a strong card with out these: A U1 card may be price it in the event you simply want an inexpensive, high-capacity possibility, for instance. V60 and V90 playing cards are price a glance in the event you’re severe about taking pictures high-resolution pictures and video as nicely. However total, playing cards with the certifications above ought to present the perfect mix of worth and efficiency immediately.
It’s necessary to emphasise that these scores are baselines. Most V30 playing cards supply considerably greater write speeds than 30 MB/s, as an illustration, and a few A1 playing cards can outperform some A2 fashions in follow. The speeds marketed by producers aren’t at all times 100% correct, both: Typically the cardboard can be slower in real-world use, different occasions it could really be a bit quicker.
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 huge 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 scores. In the event you shoot a lot of 4K to 8K video or incessantly use burst mode to seize extremely high-res pictures, the efficiency features of a great UHS-II card can prevent time.
However these are far more costly than UHS-I playing cards: This 128GB Lexar Professional Gold mannequin, as an illustration, is a relative cut price at $40. Whereas that is lower than many UHS-II fashions we’ve seen prior to now, it is nonetheless greater than double the everyday worth of our prime 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 worth premium for most individuals, so we caught largely to UHS-I playing cards right here.
We’ll additionally observe Samsung’s recent announcement of a brand new 256GB microSD card primarily based on a wholly completely different commonplace known as SD Categorical. That is theoretically a lot quicker than any UHS-I or UHS-II possibility: 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 huge 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 can be someday later in 2024.
A observe 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 via proprietary extensions. You want a suitable card reader and host system to benefit from that further 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 assist the UHS-I interface and don’t transcend its official pace, flattening any sequential features some playing cards could 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, a protracted guarantee is at all times good to have. Many producers supply lifetime restricted warranties, although we’ve observed that “endurance” playing cards marketed to resist extra hours of writing are often lined for a a lot shorter time period.
Avoiding counterfeits
The reminiscence card market has had a selected drawback with scammers promoting faux merchandise. To protect towards this, solely purchase from a identified model and a good retailer equivalent to Greatest 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 prior to now.) Keep in mind: If a worth appears too good to be true, it most likely is. Be cautious of any retailer providing considerably a cheaper price than others.
When you obtain a card, examine 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 attainable, given its specs). You can too use software program that’s designed to confirm the true capability and efficiency of your card, equivalent to H2testw and FakeFlashTest.
How we examined
We put 13 microSD playing cards via 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 just a few “real-world” checks. We copied and pasted a small folder of pictures 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 varieties 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 attainable, although for just a few 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.

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 scores: U3, V30 and A2. Its sequential learn efficiency (round 165 MB/s) isn’t fairly as fast as among the different playing cards under, so it is not absolutely the quickest for accessing giant 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 robust speeds at a comparatively reasonably priced worth. The cardboard initially began at $19 for 128GB, $30 for 256GB and $60 for 512GB, however previous 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 just a few {dollars} extra. Both approach, the cardboard comes with a 10-year restricted guarantee.
In the event you choose to purchase the Professional Plus, be sure you get the latest-generation mannequin. Samsung remains to be promoting the prior iteration of the Professional Plus, which seems to be equivalent however isn’t as fast. As a substitute, 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 resulting from inventory points with the 128GB mannequin on the time of testing, however this shouldn’t have a significant influence on real-world efficiency, as Samsung charges each playing cards identically. Proper now the cardboard is out there as much as 512GB, however the firm says 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 quicker sequential learn speeds

The Samsung Pro Ultimate is a step-up mannequin in Samsung’s microSD lineup and, as anticipated, it’s slightly bit quicker than the Professional Plus throughout the board. Its largest features are in sequential learn speeds, which have been the quickest we examined and averaged near Samsung’s marketed charge charge of 200 MB/s throughout our numerous benchmarks. You’ll want to purchase the cardboard with Samsung’s USB reader to attain that efficiency, however that could possibly be price it in the event you often 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 vital in comparison with the Professional Plus and the opposite prime UHS-I playing cards we examined.
The primary query is price. In the event you see the Professional Final accessible for a similar worth because the Professional Plus, you may as nicely seize it as an alternative. It comes with the identical 10-year guarantee and ought 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 nearly at all times be slightly bit cheaper — and thus a greater worth for many wants, particularly at greater capacities.

If the Samsung Professional Plus ever turns into unavailable, the Kingston Canvas Go Plus is one other robust various. This can be 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 Check. It successfully tied with SanDisk’s Excessive and Nintendo Change-branded playing cards in our giant 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 a great possibility for apps and video games. However it’s onerous to justify in the event you see it priced greater than the Professional Plus or Final.
- Sooner sequential write speeds than Professional Plus for a (usually) cheaper price 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 prime picks, notably in relation to sequential write speeds (just below 70 MB/s on CrystalDiskMark), so it’s not perfect for cameras. Nonetheless, it’s completely usable for a lot of use instances — a Nintendo Change, as an illustration — 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 really useful cheapo card, regardless of the Evo Choose having greater V30, U3 and A2 scores. Whereas the Professional Plus has come near these costs, the Evo Choose tends to take a seat there extra often. The 512GB variant is a very nice cut price in the event you simply want a piece of area on a budget. (The Extremely is out there in 1TB and 1.5TB capacities, although.)
Much like the Professional Plus above, Samsung is now promoting two variations of the Evo Choose: a “commonplace” mannequin with sequential learn speeds rated at 130 MB/s, and a “new generation” model that bumps that spec as much as 160 MB/s. For this decide, we particularly advocate the previous. The brand new mannequin did certainly ship these improved reads in our benchmarks, however its efficiency is nearly equivalent in any other case. As we write this, it prices $4 to $8 further, relying on what capability you select. That makes it too near the Professional Plus, which pumps out barely quicker reads and considerably higher sequential writes and random speeds. The purpose of this suggestion is to present you a card that performs nicely sufficient for filth low cost; for now, the older Evo Choose stays a greater instance of that. If the upgraded model drops additional in worth, it’ll be price contemplating, however immediately most individuals keen to pay for a pace increase ought to get certainly one of our different picks as an alternative.
- Usually accessible for cheaper price than Professional Plus
- Stable efficiency in the event you simply need a suitable card for affordable
- Slower than picks above, notably in sequential write and random efficiency benchmarks
- No 1TB mannequin
Different notable microSD playing cards
Delkin Units Energy
We didn’t use it ourselves, however in the event you’re keen 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 will ship considerably quicker sequential write speeds than our picks above. It’s one of many few UHS-II playing cards we might really discover in inventory, nevertheless it prices a ton, with a 128GB mannequin usually priced at $93.
SanDisk Excessive
The SanDisk Extreme successfully matched the Professional Plus in just a few of our sequential write checks and delivered sequential reads about on par with the Canvas Go Plus, however that was partly resulting from us solely having the ability to safe the cardboard’s 256GB mannequin, which is higher-rated than the 128GB model. It’s a effective selection in the event you 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 microSDXC Card for Nintendo Change
The SanDisk microSDXC Card for Nintendo Switch is one other first rate possibility in the event you 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 in response to CrystalDiskMark as nicely, and it is usually priced greater than our prime decide. SanDisk backs the cardboard with a lifetime guarantee, nevertheless, plus it’s accessible in a 1TB capacity. Observe that we examined the Apex Legends model of the 128GB card; SanDisk additionally sells a Super Mario model, however we are able to’t communicate as to whether 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 primary 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 quicker 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 observed its speeds peak and dip extra noticeably in our file switch check. Nonetheless, it’s not sluggish, so relying on its worth, it may be a great cut price in the event you 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 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 affordable, nevertheless it was nicely behind in our sequential checks.
