Memory cards are where camera shops make their margin, because the packaging is a wall of numbers designed to make you spend more: 200MB/s, UHS-II, V90, 2TB. Almost none of it matters for what most people actually do. Get one number right and you can ignore the rest — and probably save yourself £180. These are the best SD cards to buy in 2026, with UK prices checked on Amazon UK on 15 July 2026 — confirm the current figure before buying.
The Short Version
- Best overall — SanDisk Extreme PRO 128GB. V30 rated, fast enough for anything, at £38.98.

- Best for long shoots — SanDisk Extreme PRO 256GB. Double the space for a day out, at £69.99.
- Best UHS-II — Lexar SILVER PRO 128GB. Only if your camera can actually use it, at £63.99.
- Best microSD — Samsung PRO Plus 128GB. For action cameras, drones and handhelds, at £37.98.
Best Overall: SanDisk Extreme PRO 128GB
The SanDisk Extreme PRO 128GB at £38.98 is the card to buy for almost every camera. It is V30 rated, which is the only spec that really matters — it guarantees a sustained write of at least 30MB/s, comfortably above what 4K video demands — and its read speeds of up to 200MB/s empty a card onto your computer quickly. SanDisk's reliability record is the other half of the argument: a memory card's job is to not lose your photos. For most people, this is where the decision ends. Check the price on Amazon
Best Value: SanDisk Extreme 128GB
Related Articles
The plain SanDisk Extreme 128GB costs £34.27 and, for video, does the same job. It carries the same V30 rating — the same guaranteed 30MB/s sustained write — so it records 4K just as reliably as its PRO sibling. You give up some read speed (up to 180MB/s rather than 200MB/s), which affects how fast you offload footage and nothing else. If you are not moving hundreds of gigabytes a week, take the cheaper card. Check the price on Amazon
Best for Long Shoots: SanDisk Extreme PRO 256GB
At £69.99 the 256GB Extreme PRO is the one to take on holiday or to a wedding, where swapping cards is a nuisance and 4K footage eats space alarmingly fast. Same V30 rating, same speeds, twice the room. That said, read the buyer section before you assume bigger is better — there is a real argument for two 128GB cards instead. Check the price on Amazon
Best UHS-II: Lexar SILVER PRO 128GB
Related Articles
The Lexar SILVER PRO at £63.99 is a UHS-II, V60 card — and it is the right pick only for a specific person. UHS-II adds a second row of contacts to lift the bus ceiling from around 104MB/s to roughly 312MB/s, which matters if you shoot burst stills on a professional body or record very high-bitrate video. In a camera that only supports UHS-I, it will run at UHS-I speeds and your money is wasted. Check your manual first. Check the price on Amazon
Best microSD: Samsung PRO Plus 128GB
For an action camera, a drone, a dashcam or a handheld console, you need microSD, and the Samsung PRO Plus 128GB at £37.98 is the sensible pick. It is UHS-I U3 rated — again, the sustained-write guarantee that 4K recording needs — and Samsung's cards have a strong reliability record in devices that get bounced around, rained on and left in hot cars.

Who Should Buy Which?
Here is the money-saving bit. Ignore the headline MB/s and buy on the V-rating. V30 guarantees 30MB/s sustained, which every mainstream camera shooting 4K needs and almost none exceeds — that is why the £38.98 SanDisk Extreme PRO is the right answer for most people. V60 and V90 cards guarantee 60MB/s and 90MB/s and exist for professional video work; a UHS-II V90 card can cost over £220, roughly six times the price, and in an ordinary camera it will not record a single better frame. Only step up if your manual explicitly lists UHS-II support. And buy two smaller cards rather than one big one: if a 256GB card fails at a wedding you lose the whole day, whereas two 128GB cards lose you half. Shooting on an action camera or drone instead?

How to Choose an SD Card
A few things decide the right card. The V-rating is the one that matters: V30 means a guaranteed 30MB/s sustained write and is the baseline for 4K, while V60 and V90 (60MB/s and 90MB/s) are for high-bitrate professional video. Older markings like Class 10 mean just 10MB/s — fine for photos, not for modern video. The bus sets the ceiling: UHS-I tops out around 104MB/s and UHS-II around 312MB/s, but a UHS-II card only reaches those speeds in a UHS-II camera. Read speed (the big number on the front, often 180MB/s or 200MB/s) affects only how quickly you copy files to a computer — it has nothing to do with whether your video records cleanly. For capacity, 128GB suits most people, 256GB is for long days, and 1TB or even 2TB cards exist but concentrate your risk. Finally, match the format to the device: full-size SD for cameras, microSD for action cameras, drones and consoles.
