A 512GB microSD card was unveiled as far back as mid-2015, but that never came to market. Maybe this new one will work out better – Integral Memory promises it will arrive in Febuary (but theres no price yet).
The new 512GB card is rated class 10, UHS-I U1 meaning it guarantees a minimum of 10MB/s sequential writes. That should be enough for 4K shooting and plenty of it it half a terabyte of memory! Thats sustained sequential speed, the card tops out at 80MB/s.
Integral is not worried about the rise of cloud storage and says consumer preferences are clear enough. On phones (or tablets) with a microSD slot, you can upgrade the storage yourself in seconds. On slot-less devices, well, you better start deleting old videos and games.
