Getting the best memory card for your camera can be a challenging prospect. Different cameras have different data and compatibility needs, and there are many different brands out there competing for your attention. Which one to choose?
The general design of the memory card hasn't changed all that much over the years. Secure Digital cards, much more commonly known as SD cards, have been around for more than two decades, and these have spawned the microSD version that's found in smartphones and tablets. The big advances in the technology have all been internal, with newer cards being able to process more and more data at much faster speeds. This is a necessary step while cameras continue to get faster and more high-quality. The card needs to be able to keep up with the data the camera is producing.
This means that if you’ve invested in one of the best cameras, you’ll most likely need a latest-generation media card that's able to keep up with the highest demands of its photo- and video-shooting capabilities. This is even the case with entry-level cameras these days, so no matter whether you're shooting on a beginner's mirrorless camera or a pro-spec DSLR, you will likely have the same question with regards to the best memory cards.

How to choose the best memory card
Of course you will have a budget in mind and will also want to go for the highest capacity card with the quickest read and write speeds you can afford. The advice here used to be to opt for several cards rather than one giant capacity option, in case the latter became corrupted in some way and images lost. But, in truth, such occurrences are rare, especially these days. If you do go for a one-size-fits all high capacity card, you’ll obviously being paying more money for more memory, but it may be worth it in the long run, as you won't have to worry about swapping cards and re-formatting to take more pictures when you run out of space.
Aside from the most common SD and microSD cards, there still exists the older but at one time just as popular CompactFlash (CF) card, along with its successor in the newer XQD format, used by some of the most celebrated current mirrorless cameras, such as the Nikon Z6 and Z7.
Unsurprisingly the XQD card has been specifically developed to cope with the increased demands of such high resolution cameras for more data storage and lightning fast read and write times – particularly important when shooting high quality RAW files and/or 4K video, as any photographer will know.
Another recent development is toughened memory cards for power users. Examples include the aptly named Sony Tough, an SDXC format card that’s dust-proof, waterproof, can resist pressures up to 16kg – as well as being super-fast.
Your own particular needs may be very different though, so we’ve chosen a variety of memory cards to suit differing requirements – and budgets! Read on to find the best camera memory card for you…
01. SanDisk Extreme PRO SD UHS-I
The best all-round SD memory card
Card type: SDXC | Capacity: Up to 512GB | Read Speed: Up to 90MB/s | Write Speed: Up to 95MB/s | Warranty: Lifetime limited warranty | Suitable for: Both photography and/or video (including 4K)
Power users are advised to check out the Extreme PRO SDXC card from long standing card manufacturer SanDisk. Available in capacities from 32GB up to an impressive 512GB, this option offers a speed class 3 rating. The real practical advantage here is not only write speeds up to an impressive 90MB/s – which means that it is able to deal with rapid fire sequential shooting and in both JPEG and Raw – but also has a extremely fast transfer speed of up to 95MB/s, which will speed up the workflow of enthusiasts and pros. Aside from making it easier to capture a sequence of Raw photographs, the data crunching on offer here also makes it suitable for 4K video shooting. To sum up, this is one capable contender.
02. Lexar Professional Class 10 UHS-II 2000X Speed
The best SD card for professional photographers
Card type: SDHC and/or SDXC | Capacity: Up to 128GB | Read Speed: Up to 300MB/s | Write Speed: Up to 260MB/s | Warranty: Lifetime limited warranty | Suitable for: Both photography and video (including 4K)
Lexar has long been the go-to card for photography enthusiasts and professional shooters, and, despite disappearing from the market for a little while, it has bounced back with plenty of Lexar options still available. A solid choice for us is the Lexar Professional 16GB Class 10 UHS-II 1000x Speed, which deploys UHS-II tech to enable transfer speeds up to 300 MB/s and write speeds up to 260 MB/s.
This ensures that, whether you’re recording full HD, 4K video, or shooting high-resolution Raw files, this card delivers the goods, even if maximum data capacity is 128GB, rather than the maximum 512GB offered by some rivals. A close alternative in terms of specification and performance would be SanDisk’s Extreme PRO SD UHS-II (also featured here), but we feel you can't really go wrong with this one.
03. SanDisk Extreme PRO SD UHS-II
An even faster card than the UHS-I Pro version
Card type: SDXC | Capacity: Up to 128GB | Read Speed: Up to 300MB/s | Write Speed: Up to 260MB/s | Warranty: Lifetime limited warranty | Suitable for: Pros wanting to shoot swift bursts of high res stills and video
Missing that essential shot if you’re working as a pro photographer can be an expensive mistake, and is especially irritating if it’s because your card can’t keep up. Try and avoid the latter ever happening by investing in this ultra speedy, inevitably costlier, example from industry stalwart SanDisk – the SanDisk Extreme PRO SD UHS-II. In offering read speeds of up to 300 MB/s and write speeds of an equally impressive 260 MB/s, it's a class leader among memory cards.
The above specification makes it a must-have option for reportage, sports and wildlife photographers, shooting bursts of rapid fire stills, or videographers wanting the clarity of 4K resolution video, with the inevitable data hungriness that comes with it. As this is an SDXC (‘Extended Capacity’) card too, storage is impressive. Available card offerings are from 32GB up to 128GB, but truly the accent is on speed here.
04. Sony SF-G Tough SDXC
A super-robust new breed of memory card
Card type: SDXC | Capacity: Up to 128GB | Read Speed: Up to 300 MB/s | Write Speed: Up to 299 MB/s | Warranty: Manufacturer’s | Suitable for: High speed burst photography and video (including 4K)
The bigger the card’s data capacity, the higher the potential worry of losing hundreds, possibly thousands of precious image files should anything untoward happen. Purporting to eliminate some of that stress is the Sony Tough range, supplied in common-use SD format. While arguably no card can claim to be 100% destruction–proof, there come with the boast of being dustproof and waterproof, while possessing ‘bend proof’ strength into the bargain – namely being able to withstand 18KG of exerted pressure (that’s18x greater than standard SD).
If you need more convincing still, Sony’s Tough has also been tested against drops from 5 metres in height, while the card can simply be washed clean of any grime that gets on it. Speed wise, a further bonus is the card’s ability to cope with the sequential capture of 241-compressed Raw or 362 JPEGs in 20fps burst shooting mode on the Sony A9. If you’re a pro shooter and have the budget, you’ll definitely want to check these out.
05. Sony XQD G Series Memory Card
The best XQD card around right now
Card type: XQD | Capacity: Up to 64GB | Read Speed: Up to 440 MB/s | Write Speed: Up to 400 MB/s | Warranty: Manufacturer’s | Suitable for: High speed burst photography and video (including 4K)
The XQD format is not used in every camera, but has been adopted by Nikon for some of its DSLRs and recent Z-series full-frame mirrorless cameras (as well as Sony’s high-end video camcorders). If you’re a Nikon user in the market for an XQD card, we reckon that the Sony Professional XQD G Series 64GB is your best bet. Its amazingly fast read and write speeds of more than 400MB/s each mean that it will more than keep up even with full-frame RAW burst shooting and 4K video, and the process of exporting your creations from camera to PC will whizz by like a dream.
The card is built tough too, with a durable outer shell designed to be robust and dust-resistant, so if you’re the type to take your camera into harsh conditions, you can be sure that the card will be able to cope. This is really the crux of the Sony XQD card – it’s able to handle whatever you and your camera throw at it, whether that’s the speed of your shoot or the conditions you find yourself in. High-end Nikon cameras deserve the best in terms of cards – make sure you give it to them.
06. Transcend SDXC UHS-II U3
Great for shooting Raw files or high-resolution video
Card type: SDXC | Capacity: Up to 64GB | Read Speed: Up to 285MB/s | Write Speed: Up to 180MB/s | Warranty: Five year limited warranty | Suitable for: Pros shooting rapid fire high res Raw stills and high quality 4K video
If it’s Raw files you primarily need to capture, then you’ll want a card that can cope with the highest quality imagery in sequential bursts – as well as one that provides a sufficient storage capacity to avoid having to swap out the media in use at that decisive moment. While the Transcend SDXC UHS-I U3's 64GB maximum capacity (the alternative being 32GB) may initially appear a little small when compared with other options here, the performance is anything but, via commendably quick read and write times of 285 MB/s and 180 MB/s respectively.
Obviously you will need UHS-II compatible DSLR or camcorder to be able to use this one – so check – but speeds of up to 3x faster than standard UHS-1 SD memory cards can be delivered. These Transcend branded cards are also shock and X-ray proof, thereby providing a degree of certainly for photo and video enthusiasts and pros.
07. Lexar Professional 633x SDHC / SDXC UHS-I
High capacity and a swift performance when shooting up to 4K video
Card type: SDHC and/or SDXC | Capacity: Up to 1TB | Read Speed: Up to 95MB/s | Write Speed: Up to 45MB/s | Warranty: Lifetime limited warranty | Suitable for: Both photography and video (including 4K) at pro level
As photographers, we always think we have enough storage capacity until suddenly we don’t. The Lexar Professional 633x SDXC UHS-I is designed for use by DSLR owners, with up to 1TB of storage capacity offered. The only (inevitable) downside is that the read and transfer rates are a little more modest than the lower capacity yet higher speed cards pitched at professionals. This means you'll need to decide which is more important to you – having the space to store many hours of video, or having the potential to transfer it between devices super-quickly. Ultimately the fact that there is a choice between the two makes us as consumers the victors.
08. PNY Elite Performance SDXC
Top capacity thumbnail-sized media card for all your digital memories
Card type: SDXC | Capacity: Up to 512GB | Read Speed: Up to 95MB/s | Write Speed: Not specified | Warranty: Lifetime (limited) | Suitable for: High speed burst photography and video (including 4K)
Though there are plenty of budget priced card offerings bearing the US-based PNY brand, this Elite Performance series, with capacities from a useful 32GB up to a generous 512GB, currently tops the range. It offers not only a high capacity, but also an industry-standard read speed of 95MB per second from an SDXC format card. The ‘Elite’ moniker signifies that these Class 10 speed, UHS-1 compatible cards are not only suitable for shooting video on a DSLR with, but are also durable with it, being waterproof, shock proof, temperature proof and magnet proof. Thus the brand is able to claim that the Elite Performance range of cards are suitable for advanced photo enthusiasts and even professionals, as well as those recording 4K quality clips. Peace of mind of a lifetime-limited warranty is provided.
09. SanDisk Extreme PRO CompactFlash
There’s nothing retro about a 160MB/s read speed
Card type: CompactFlash | Capacity: Up to 256GB | Read Speed: Up to 160MB/s | Write Speed: Up to 150MB/s | Warranty: Lifetime limited warranty | Suitable for: Both photography and video (including 4K)
Compact flash cards may be older and bulkier than the newer SD format alternative, but that doesn't mean they can't still deliver sufficient capacity and speed to satisfy today’s DSLR user. A case in point is SanDisk’s CompactFlash range, which offers capacities from a useful 16GB to a power user 256GB, so you don’t have to swap out media cards in the heat of the action.
Also impressive with this one is write speeds of up to 140MB/s at maximum 256GB capacity (otherwise it’s 150 MB/s for the 128GB and lower capacities), which also makes it just as suited to video use, particularly for those DSLRs also offering Full HD capture. In fact, with a minimum sustained write speed of 65MB/s, the claim by its manufacturer is that this one is class leading.
10. Transcend CompactFlash 800
Transcend’s CF gives plenty of data storage for your buck
Card type: CompactFlash | Capacity: Up to 256GB | Read Speed: Up to 120MB/s | Write Speed: Up to 60MB/s | Warranty: Five year limited warranty | Suitable for: Both photography and video (including Full HD)
While it may not be as recognisable to the casual observer as competing card brands, Transcend is one of the longer-term players in the market – and, usefully, still makes many low-capacity cards, holding obvious appeal for those on tighter budget. However, even the higher capacity offerings that may appeal to semi pro DSLR users – such as this CompactFlash 800 series – are hardly expensive for what’s on offer.
Capacities run from a standard 32GB up to a slightly more impressive 256GB. Specification is also solid for a budget card; here we get read speeds of up to 120 MB/s and write speeds of 60 MB/s. Actual performance of course is affected by camera hardware and software, as is the case with any card. However, here there’s even a built-in error correcting code to detect and correct any transfer errors.
11. Samsung PRO Endurance
The best MicroSD card, suitable for an array of devices
Card type: microSD (With SD adapter) | Capacity: Up to 128GB | Read Speed: Up to 100MB/s | Write speed: Up to 30MB/s | Warranty: Up to 5 years | Suitable for: Action cameras, dashcams, security cameras
The Samsung PRO Endurance is our pick for the best MicroSD card around right now. It does cost a little more to get a microSD card with larger SD card-sized adapters, although this series is still very reasonably priced.
The draw here includes the fact that the cards are claimed to be able to withstand harsh environments, are longer lasting and are particularly suited to use in action cameras. This is because they can continually record at high read/write speeds (100MB/s and 30MB/s, respectively). Also promised for the highest capacity card is an industry best of 43,800 hours of continuous video recording. Peace of mind comes courtesy of warranties of between two years for the lower capacity cards, to five years for maximum capacity cards.
12. Samsung EVO Plus
Inexpensive microSD cards with SD card adapter
Card type: microSD (With SD adapter) | Capacity: Up to 512GB | Read Speed: Up to 100MB/s | Write Speed: Up to 30MB/s | Warranty: 10 years | Suitable for: Day to day photography
Arriving with us in 32GB, 64GB, 128GB, 256GB and 512GB capacities, these Class 10 microSD cards handily come with an SD adapter that allows them to be used in cameras just as easily as a smartphone or tablet. Costing less than £20 for the lowest 32GB capacity, this seems like good value considering they manage read speeds of 100 MB/s (albeit a modest write speed of 30MB/s). A bright red design also ensures this jack of all trades option from Samsung won’t readily get lost down the back of the sofa, despite being fingernail sized. Peace of mind also comes via a 10 year limited warranty, plus the fact that the cards are claimed as waterproof, temperature proof, X-ray proof and magnetic proof.
