Maya L. Used for: More than a year
Pros
Been in three cameras and outlasted two of them
Comment
This card has been through a season of junior football, a house move and a fortnight in Morocco, and the only attention it has ever needed is a format twice a year
Charlie K. Used for: 1–3 months
Pros
Never had to change a card mid-event
Cons
Slower than UHS-II if you need that
Comment
One card, a whole weekend festival, nothing to think about
Ivy L. Used for: More than a year
Cons
Loses a slice of the capacity to formatting and nobody warns you
Comment
Worth saying plainly for anyone about to panic: a 1TB card shows up as roughly 931GB in a computer and something different again in some cameras, and neither of those means you have been sold a short card. Manufacturers count in round thousands, computers count in 1024s, and the difference is the missing chunk. Beyond that the card has been exemplary. Two years of family holidays, school plays and one very muddy Scout camp, and every photo has come off it intact. It is the only card in the house I trust without thinking.
Amelia L. Used for: More than a year
Pros
Still the card that goes in the primary slot
Cons
You do notice the write speed on long bursts of raw
Comment
Ordinary hobby use, nothing exotic, and after 18 months there is nothing to say except that it works. No errors, no lost files, no format prompts. Cards are boring when they are good, and this one is extremely boring.

Pros
Two years in a dashcam that never stops writing
Cons
Loop recording has started leaving the odd corrupt clip
Comment
A dashcam is the cruellest thing you can do to an SD card: constant overwriting, never powered down gently, baked on a windscreen all summer and frozen all winter. This one has taken it for two years, which is longer than the three cards before it managed between them. It is starting to show, mind. Perhaps one clip in fifty now comes back with a glitch in the middle, and a health check reports a handful of reallocated blocks. That is fair wear for what it has been through rather than a fault, but if you are buying one for a dashcam, buy it knowing it is a consumable.

Pros
The read speed on the box is the read speed I measured
Comment
Straight out of the packet it went into a reader before anything else, because at this price I wanted to know exactly what I had bought. CrystalDiskMark gave a read figure within a couple of megabytes of the number printed on the front, which is more honest than most, and a sequential write about half that, which is exactly what the class rating on the back promises rather than the headline. That distinction catches people out constantly. The big number is read, the small one is write, and the small one is what matters when your camera is recording. Four stars only because a terabyte on UHS-I is a lot of eggs in a fairly slow basket, and I would have paid more for a UHS-II version if it existed at this capacity.

Comment
A terabyte in a camera bag still feels like science fiction to someone who started on film
Rosie G. Used for: Less than a month
Pros
Big enough that a whole trip fits on one card
Cons
Feels risky having everything in one place
Comment
Juggling four small cards on Japanese trains was the thing I wanted to avoid, so I bought this before a fortnight out there. Came home with the whole trip on one card, about nine thousand photos and a pile of 4K, and it never once complained. Whether that was wise is another question.

Pros
Survived a fall into a canal and a night in a bag of rice
Cons
The label peels at the corner
Comment
It went in the water with the camera bag on a towpath and I had written off both. The camera was fine after drying, and the card came up first time with every photo from that morning still on it. Waterproof claims on packaging usually mean nothing to me, but that one I now believe!
George D. Used for: 3–6 months
Comment
Four stars and the missing one is nothing to do with performance. The card is quick, the capacity is real once you allow for the way computers count, and it has not missed a beat in a bridge camera. But a terabyte at this price on a UHS-I bus is a strange product, and two 512s would have been the sensible buy.
