Most microSD playing cards are quick sufficient for stashing pictures, recording video and transferring information, however some will get you somewhat extra bang to your buck than others. In case you’re trying to enhance the interior storage of your Nintendo Swap, Steam Deck, GoPro, Raspberry Pi or every other gadget 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 means of a spread of benchmark assessments: Listed below are one of the best that we’ve examined, together with some common recommendation on what to search for when shopping for a brand new card.
Editor’s be aware (4/24/24): Samsung has launched an upgraded model of our “greatest worth” choose, 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 suggest
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 house you want. Trendy playing cards are often obtainable in sizes starting from 32GB to 512GB, whereas a handful provide 1TB fashions as nicely. 2TB playing cards are theoretically doable however nonetheless in the prototype stage.
For many, a 128GB or 256GB mannequin ought to be the candy spot between worth and space for storing. However should you want extra room — say, for stashing a bunch of video games on a Steam Deck — a 512GB card may make extra sense and infrequently supplies a greater cost-per-GB ratio. Nowadays, you will discover a good 128GB card for round $15 or much less, 256GB card for lower than $30 and a stable 512GB card for lower than $40 (although many value nearer to $50 or $60). There’s a starker enhance once you go as much as 1TB playing cards, which generally value nearer to $100.
Word {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 provide as much as 130 MB/s.
Once we speak about microSD playing cards at this time, we often seek advice from playing cards that use the microSDXC (eXtended Capability) normal, which have a capability between 32GB and 2TB. Your gadget must help this for it to work with a microSDXC card. This may virtually by no means be a difficulty nowadays, however some older units (a Nintendo 3DS, for example) 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). Typically, 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 information, resembling 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 necessary. Random efficiency, in the meantime, is about how rapidly a card can learn and write small information scattered all through the gadget.
Since random learn/write speeds are a lot decrease than sequential ones, storage gadget makers have a tendency to not promote them as loudly. However they’re necessary should you use a card with a gaming gadget or a single-board laptop just like the Raspberry Pi, the place it typically has to quickly save and entry small bits of information in random areas.
Pace scores
In case 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 velocity class and efficiency scores, 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 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 velocity of at the least 30 MB/s. This ought 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 increased value.
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 ranking overlaps with the opposite two techniques. 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 ranking is much less related these days, however you should still see a “C10” brand on some playing cards.
The Software 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, quite than MB/s. There are two classes right here: A1 playing cards provide 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 scores additionally assure sequential write speeds of at the least 10 MB/s.
To maintain it easy, most individuals ought to search for a card with V30, U3 and A2 scores. It’s completely doable to get a stable card with out these: A U1 card is perhaps price it should you simply want an inexpensive, high-capacity choice, for instance. V60 and V90 playing cards are price a glance should you’re critical about taking pictures high-resolution pictures and video as nicely. However general, playing cards with the certifications above ought to present one of the best mix of worth and efficiency at this time.
It’s necessary to emphasise that these scores are baselines. Most V30 playing cards provide considerably increased write speeds than 30 MB/s, for example, and a few A1 playing cards can outperform some A2 fashions in observe. The speeds marketed by producers aren’t all the time 100% correct, both: Typically the cardboard might be slower in real-world use, different instances 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 obtainable at this time 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 may attain as much as 312 MB/s. (A UHS-III normal exists as nicely however hasn’t seen extensive adoption.) These are labeled on the cardboard with a Roman numeral I or II.
The quickest microSD playing cards you should purchase proper now are UHS-II playing cards, they usually’re often those with V60 or V90 scores. In case you shoot numerous 4K to 8K video or steadily use burst mode to seize extremely high-res pictures, the efficiency features of UHS-II card can prevent time.
However these are far more costly than UHS-I playing cards: As an example, this 128GB mannequin from Lexar is a good discount at $40. That’s lower than many UHS-II fashions we’ve seen prior to now however nonetheless greater than double the everyday worth of our high 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 definitely worth the worth premium for most individuals, so we caught largely to UHS-I playing cards right here.
We’ll additionally be aware Samsung’s current announcement of a brand new 256GB microSD card primarily based on a completely totally different normal known as SD Specific. 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 Specific has technically been round for a number of years however hasn’t seen extensive adoption, so precisely how this card performs in actuality — and the way a lot it’ll value — stays to be seen. We’ll check the gadget as soon as it turns into obtainable, which Samsung says might be someday later in 2024.
A be aware 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 by means of proprietary extensions. You want a appropriate card reader and host gadget to benefit from that additional efficiency, although. In case you discover a UHS-I card promoting speeds increased than 104 MB/s, that is what’s happening. You possibly can see these limits in motion with a Nintendo Swap or Steam Deck: Each of these gaming units help the UHS-I interface and don’t transcend its official velocity, flattening any sequential features 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 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 coated for a a lot shorter time frame.
Avoiding counterfeits
The reminiscence card market has had a selected downside with scammers promoting pretend merchandise. To protect in opposition to this, solely purchase from a recognized model and a good retailer resembling 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 prior to now.) Bear in mind: If a worth appears too good to be true, it in all probability is. Be cautious of any retailer providing considerably a cheaper price than others.
When you obtain a card, test its packaging for any irregularities. You possibly can run benchmark assessments like CrystalDiskMark or BlackMagic Disk Pace Take a look at to confirm its speeds aren’t drastically decrease than what’s marketed (or doable, given its specs). You may as well use software program that’s designed to confirm the true capability and efficiency of your card, resembling H2testw and FakeFlashTest.
How we examined
We put 13 microSD playing cards by means of a collection of assessments to confirm their sequential and random efficiency. These included benchmarks like CrystalDiskMark, BlackMagic Disk Pace Take a look at, ATTO Disk Benchmark and AJA System Take a look at, in addition to just a few “real-world” assessments. We copied and pasted a small folder of pictures about 1.15GB in measurement 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, Metallic 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 doable, 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 Reminiscence Card Formatter instrument.

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 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 beneath, so it isn’t absolutely the quickest for accessing giant information saved in your card, however the distinction is small in real-world use.
The primary purpose the Professional Plus tops our checklist is as a result of it delivers these sturdy speeds at a comparatively inexpensive worth. The cardboard initially began at $19 for 128GB, $30 for 256GB and $60 for 512GB, however current 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 means, the cardboard comes with a 10-year restricted guarantee.
In case 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 similar 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 as a result of inventory points with the 128GB mannequin on the time of testing, however this shouldn’t have a significant impression 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 it’ll launch a 1TB mannequin later in 2024.
- Constantly fast sequential and random learn/write efficiency
- Nice worth
- Simply obtainable at trusted retailers
- Some friends have barely sooner sequential learn speeds
- No 1TB mannequin

The Samsung Professional Final 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 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 varied benchmarks. You’ll want to purchase the cardboard with Samsung’s USB reader to attain that efficiency, however that may very well be price it should you repeatedly 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 high UHS-I playing cards we examined.
The primary query is value. In case you see the Professional Final obtainable for a similar worth because the Professional Plus, you would possibly 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 inexpensive, however the Professional Plus will virtually all the time be somewhat bit cheaper — and thus a greater worth for many wants, particularly at increased capacities.
- Quickest microSD card we examined (with acceptable USB reader)
- Simply obtainable at trusted retailers
- Professional Plus is healthier worth for many

If the Samsung Professional Plus ever turns into unavailable, the Kingston Canvas Go Plus is one other sturdy 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 Pace Take a look at. It successfully tied with SanDisk’s Excessive and Nintendo Swap-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 choice for apps and video games. Nevertheless it’s exhausting to justify should you see it priced increased than the Professional Plus or Final.
- Sooner sequential write speeds than Professional Plus for a (sometimes) 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 Choose is a transparent step behind our high picks, significantly relating to sequential write speeds (slightly below 70 MB/s on CrystalDiskMark), so it’s not preferrred for cameras. Nonetheless, it’s completely usable for a lot of use instances — a Nintendo Swap, for 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 Extremely, a steadily beneficial cheapo card, regardless of the Evo Choose having increased V30, U3 and A2 scores. Whereas the Professional Plus has come near these costs, the Evo Choose tends to sit down there extra repeatedly. The 512GB variant is a very nice discount should you simply want a piece of house on a budget. (The Extremely is out there in 1TB and 1.5TB capacities, although.)

Different notable microSD playing cards
Delkin Units Energy
We didn’t use it ourselves, however should you’re prepared 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 will ship considerably sooner sequential write speeds than our picks above. It’s one of many few UHS-II playing cards we may truly discover in inventory, but it surely prices a ton, with a 128GB mannequin usually priced at $93.
SanDisk microSDXC Card for Nintendo Swap
The SanDisk microSDXC Card for Nintendo Swap is one other respectable choice should you ever see it obtainable 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 accordance with CrystalDiskMark as nicely. The 128GB model of this card is priced round $18 as of this writing, whereas the 512GB mannequin prices round $50; each are increased than the Professional Plus. SanDisk backs the cardboard with a lifetime guarantee, nonetheless, plus it’s obtainable in a 1TB capability. Word that we examined the Apex Legends model of the 128GB card; SanDisk additionally sells a Tremendous Mario mannequin, however we are able to’t communicate as to whether that one performs any otherwise.
Lexar Skilled 1066x
Equally, the Lexar Skilled 1066x is a good various to the Professional Plus if our predominant 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 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 seen its speeds peak and dip extra noticeably in our file switch check. Nonetheless, it’s not gradual, so relying on its worth, it is perhaps discount should you want quick write speeds for video recording and the like. It’s additionally obtainable in 1TB, plus it comes with a lifetime restricted guarantee.
SanDisk Excessive
The SanDisk Excessive successfully matched the Professional Plus in just a few of our sequential write assessments and delivered sequential reads about on par with the Canvas Go Plus, however that was partly as a result of us solely having the ability to safe the cardboard’s 256GB mannequin, which is higher-rated than the 128GB model. It’s a fantastic alternative should you see it on sale at a good vendor, however its random efficiency lagged behind the Samsung Professional and Kingston playing cards, and it sometimes prices extra. It does have a 1TB mannequin, although.
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 wasn’t too far off the random learn/write efficiency of the Professional Plus and Professional Final in CrystalDiskMark, and it typically goes for reasonable, but it surely was nicely behind in our sequential assessments.
