Most microSD playing cards are quick sufficient for storing and transferring information, however some will present just a little extra bang for the buck than others. In case you’ve received a tool that helps the format — be it a Nintendo Swap or different gaming handheld, a GoPro, a Raspberry Pi or a touch cam — we’ve researched the market and put greater than a dozen prime microSD playing cards via a bunch of benchmark checks. You could find the playing cards that stood out probably the most beneath, alongside some common issues to know before you purchase.
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 cupboard space you want. Fashionable playing cards are often accessible in sizes starting from 32GB to 512GB, whereas an rising quantity can be found in 1TB as nicely. 2TB playing cards from respected producers are getting nearer however aren’t broadly accessible simply but.
For many, a 128GB or 256GB mannequin ought to be the candy spot between value and cupboard space. However in the event you want extra room — say, for stashing a bunch of video games on a Steam Deck — a 512GB or higher card may make extra sense and infrequently supplies a greater cost-per-GB ratio. Nowadays, you could find a good 128GB card for round $15 or much less, a very good 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 once you go as much as 1TB playing cards, which generally price nearer to $100.
Observe {that a} microSD card’s efficiency might differ relying on what capability you purchase. SanDisk says its 128GB Excessive 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 speak about microSD playing cards immediately, we often discuss with playing cards that use the microSDXC (eXtended Capability) customary, which have a capability between 32GB and 2TB. Your system must assist this for it to work with a microSDXC card. This can nearly by no means be a problem lately, however some older units (a Nintendo 3DS, as an illustration) are solely appropriate 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 once you’re making an attempt to entry or save lengthy, fixed streams of knowledge, equivalent to opening a big video or copying an enormous batch of information from a PC. If you wish to use a microSD card for media storage, that is significantly 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 in the event you use a card with a gaming system or a single-board laptop just like the Raspberry Pi, the place it typically has to quickly save and entry small bits of knowledge in random places.
Pace rankings
In case you have a look at a microSD card, you’ll see a buffet of numbers, letters and symbols. Most of those discuss with the cardboard’s velocity class and efficiency rankings, that are decided by the SD Affiliation.
A card’s Video Pace Class, or V-rating, particulars its minimal sequential write velocity, which is particularly essential when recording video from a digital camera. It ranges from V6 to V90. Many of the playing cards we examined had a V30 score, so that they have a sequential write velocity 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 Pace Class, or U-rating, additionally refers to a card’s minimal sequential write velocity. 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 Pace 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 velocity. This score is much less related these days, however you should still see a “C10” emblem 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, reasonably than MB/s. There are two classes right here: A1 playing cards supply a minimal random learn velocity of 1,500 IOPS and a minimal random write velocity 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 attainable to get a strong card with out these: A U1 card may be value it in the event you simply want an affordable, high-capacity choice, for instance. V60 and V90 playing cards are value a glance in the event you’re severe about capturing high-resolution images and video as nicely. However total, playing cards with the certifications above ought to present the very best mix of value and efficiency immediately.
It’s essential to emphasise that these rankings 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: Generally the cardboard can be slower in real-world use, different occasions it might really 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 velocity of 104 MB/s. There are additionally UHS-II playing cards, which have an additional row of pins on the again and might attain as much as 312 MB/s. (A UHS-III customary exists as nicely however hasn’t seen vast 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 case you shoot a lot of 4K to 8K video or continuously use burst mode to seize extremely high-res images, the efficiency good points of a very good UHS-II card can prevent time.
However these are far more costly than UHS-I playing cards: This 128GB Lexar Skilled Gold mannequin, as an illustration, is a relative cut price at $40. Whereas that is lower than many UHS-II fashions we’ve seen up to now, it is nonetheless greater than double the standard value of our prime choose talked about beneath. You want a tool that’s appropriate with the UHS-II interface to see any advantages, too, and inventory for UHS-II playing cards is usually 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 observe Samsung’s announcement earlier this 12 months of a brand new 256GB microSD card based mostly on a wholly totally different customary 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 round for a number of years however hasn’t seen vast 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 Swap and Steam Deck
Whereas the UHS-I spec has a theoretical most of 104 MB/s, some UHS-I playing cards can exceed that velocity via proprietary extensions. You want a appropriate card reader and host system to benefit from that additional efficiency, although. In case you discover a UHS-I card promoting speeds greater than 104 MB/s, that is what’s happening. You’ll be able to see these limits in motion with a Nintendo Swap or Steam Deck: Each of these gaming units assist the UHS-I interface and don’t transcend its official velocity, flattening any sequential good points 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, a protracted guarantee is at all times good to have. Many producers supply lifetime or 10-year restricted warranties, although we’ve observed that “endurance” playing cards marketed to face up to extra hours of writing are often coated for a shorter time period. For instance, Samsung’s Professional Endurance, a mannequin aimed toward safety cameras and different monitoring units, comes with a five-year guarantee.
Avoiding counterfeits
The reminiscence card market has had a specific drawback with scammers promoting faux merchandise. To protect towards this, solely purchase from a recognized model and a good retailer equivalent to Finest Purchase, B&H Photograph or Adorama. In case 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 straight 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, test its packaging for any irregularities. You’ll be able to run benchmark checks like CrystalDiskMark or BlackMagic Disk Pace Check to confirm its speeds aren’t drastically decrease than what’s marketed (or attainable, given its specs). You can even 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 Pace Check, ATTO Disk Benchmark and AJA System Check, in addition to just a few “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 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, Steel Gear Rising: Revengeance and Apex Legends — then timing how lengthy it took to launch every sport 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 had been solely capable of check their 256GB fashions. We additionally reformatted every card earlier than testing with the SD Affiliation’s Reminiscence Card Formatter instrument.

Storage capability: 128GB, 256GB, 512GB, 1TB | Pace courses: U3, V30, A2, Class 10 | Guarantee: 10-year restricted
The Samsung Professional Plus was practically the quickest card we examined when it comes to sequential write efficiency (round 130 MB/s in CrystalDiskMark) and was an in depth second when it comes to random learn/write speeds, so it ought to work nice whether or not you’re shopping for for a digital camera, Android 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 number of the different playing cards beneath, 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 principle purpose the Professional Plus tops our listing is as a result of it delivers these robust speeds at a comparatively reasonably priced value. 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. In case you want extra space, the corporate just lately launched a brand new 1TB mannequin that ought to be simply as quick, although that one is presently far more costly at $120. Both manner, the cardboard comes with a 10-year restricted guarantee.
In case you decide 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 appears to be like an identical 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 attributable to inventory points with the 128GB mannequin on the time of testing, however this shouldn’t have a serious impression on real-world efficiency, as Samsung charges each playing cards identically.
- Constantly fast sequential and random learn/write efficiency
- Nice worth
- Available at trusted retailers
- Has a 1TB choice
- Some friends have barely sooner sequential learn speeds

The Samsung Professional Final is a step-up mannequin in Samsung’s microSD lineup and, as anticipated, it’s just a little bit sooner than the Professional Plus throughout the board. Its greatest good points are in sequential learn speeds, which had been the quickest we examined and averaged near Samsung’s marketed fee fee of 200 MB/s throughout our varied benchmarks. You’ll want to purchase the cardboard with Samsung’s USB reader to realize that efficiency, however that might be value it in the event you usually 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 prime UHS-I playing cards we examined.
The principle query is price. In case you see the Professional Final accessible for a similar value because the Professional Plus, you may as nicely seize it as a substitute. 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 just a little bit cheaper — and thus a greater worth for many wants, particularly at greater capacities. There isn’t any 1TB choice right here, both.
- Quickest microSD card we examined (with acceptable USB reader)
- Simply accessible at trusted retailers
- Professional Plus is healthier worth for many
- No 1TB mannequin

If the Samsung Professional Plus ever jumps too excessive in value or turns into unavailable, the Kingston Canvas Go Plus is one other robust different. 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 Pace Check. It successfully tied with SanDisk’s Excessive and Nintendo Swap-branded playing cards in our giant file switch speeds check. 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 had been solely bested by Samsung’s Professional playing cards in benchmarks, so it’s nonetheless a very good choice for apps and video games. The 1TB model can also be $20 cheaper than the equal Professional Plus, so it ought to be a good worth in the event you want a lot of area and need to save money. However the different fashions are laborious to justify in the event you see them hovering in the identical value vary as our picks above.
- Quicker sequential write speeds than Professional Plus for a (usually) lower cost than Professional Final
- Lifetime restricted guarantee
- Has a 1TB choice
- Professional Plus is often a greater worth for many
- Slower sequential write speeds than picks above

The Samsung Evo Choose is a transparent step behind our prime picks, significantly in the case of sequential write speeds (just below 70 MB/s on CrystalDiskMark), so it’s not splendid for cameras. Nonetheless, it’s completely usable for a lot of use circumstances — a Nintendo Swap, 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 Extremely, an oft-recommended 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 nearly at all times retails for much less.
Much like the Professional Plus, now you can discover two variations of the Evo Choose: a “standard” mannequin with sequential learn speeds rated at 130 MB/s, and a “new generation” mannequin that bumps that spec as much as 160 MB/s. Because the level of this suggestion is to provide you a card that performs nicely sufficient for as little as attainable, it’s best to get whichever one is cheaper within the capability you need. The brand new mannequin did certainly ship these improved reads in our benchmarks, nevertheless it performs nearly identically in any other case, so you will not lose a lot by saving a couple of dollars with the older technology.
The one massive distinction is that the up to date mannequin is the one one accessible in a 1TB capability; we’ve not examined that particular mannequin, however at $80 it ought to be value a glance if pricing is your solely concern.
- Usually accessible for lower cost than Professional Plus
- Strong efficiency in the event you simply need an appropriate card for reasonable
- Has a 1TB choice
- Slower than picks above, significantly in sequential write and random efficiency benchmarks

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 Units Energy has examined nicely elsewhere and may ship considerably sooner sequential write speeds than our picks above. It’s one of many few UHS-II playing cards we may really discover in inventory, nevertheless it prices a ton, with a 128GB mannequin usually priced round $90.
SanDisk Excessive
The SanDisk Excessive 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 attributable to us solely having the ability to safe the cardboard’s 256GB mannequin, which is higher-rated than the 128GB model. It’s a effective alternative 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 typically prices extra.
SanDisk microSDXC Card for Nintendo Swap
The SanDisk microSDXC Card for Nintendo Swap is one other respectable choice in the event you ever see it accessible for lower than the Professional Plus and Canvas Go Plus. Its sequential learn speeds had been about the identical because the latter in our benchmarks, however its sequential writes had been barely slower (and farther behind the Professional Plus). Its random learn/writes had been a bit behind in response to CrystalDiskMark as nicely, and it is typically priced greater than our prime choose. SanDisk backs the cardboard with a lifetime guarantee, nonetheless, plus it’s accessible in a 1TB capability. Observe that we examined the Apex Legends model of the 128GB card; SanDisk additionally sells a Tremendous Mario mannequin, however we won’t say if that one performs any in another way.
Lexar Skilled 1066x
Equally, the Lexar Skilled 1066x is a good different 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 had been a bit sooner than the Canvas Go Plus and SanDisk Swap 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 gradual, so relying on its value, it may be a very good cut price in the event you want quick write speeds for video recording and the like. It’s additionally accessible in 1TB, plus it comes with a lifetime restricted guarantee.
SanDisk Excessive Professional
The SanDisk Excessive Professional 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 typically goes for reasonable and wasn’t too far off the random learn/write efficiency of Samsung’s Professional playing cards in CrystalDiskMark, nevertheless it was nicely behind in our sequential checks.
Latest updates
August 2024: We’ve up to date this information to notice the just lately launched 1TB fashions for 3 of our prime picks: the Samsung Professional Plus, the Kingston Canvas Go Plus and the Samsung Evo Choose. We’ve additionally made certain all pricing particulars are as updated as they are often. We intention so as to add testing data on new playing cards, together with Lexar’s Skilled Silver Plus and SanDisk’s new Pokémon-themed fashions, with one other replace within the close to future.
