Comment on SanDisk introduces the first 8TB SD and 4TB microSD cards - Liliputing

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.

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

  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.
