I am slightly confused why they use UHS-I instead of UHS-II (or even UHS-III) for such a big capacity. Seems like people needing so much capacity probably write a lot of data in a short time. UHS-II is 3 times quicker.

Then again maybe they are aiming for devices that can't even run UHS-II

Could be a trade-off issue. They can get capacity or speed but not both yet.

Or it's cost-prohibitive ATM. As in, they could get both, but you'd pay a ton for it.

I can imagine this being useful for cases where you write a lot of data over a longer time period. Think CCTV (with low-medium resolution). You can keep a sizeable archive locally and never have to swap cards

[–] Visstix@lemmy.world 11 points 4 months ago

Oh yeah cctv could be a good option indeed.

I assume larger capacity means longer endurance, too, since you're not constantly rewriting the same cells.

It's SanDisk, I expect the opposite - that every cell increases the volatility and chance of catastrophic failure.
