This card isn't UHS-I

It doesn't even so say on the card and the package so where that idea comes from...

This is a USH-I card.


You see the difference, the Class 10 rating is replaced with the UHS-I rating.

Yeah, hope its genuine,
the looks of it, old stock I think, pre UHS-I era. But class 10 will do for me, not shooting videos anyway.

Oh great...now we have four competing systems for rating the speed of a card. Why can't they settle on one?

You can look up the part number at Sandisk's own website, and it's also stated to be UHS-1 there, with the same product pictures.

Edit: The Roman numeral I on the card is a UHS-1 symbol.

Maybe a mistake?
No idea what actually the minium is off UHS-I but all 30MB/s cards are rated class 10 by my knowledge, USH-I seems to be starting at 40~45 MB/s

okay i got it wrong with the classifications...

Class 10 has minimum speed of 10 MB/s
USH-I also has a minimum speed of 10 MB/s

The differnce is the data rate for non UHS-I cards is 50 mhz while UHS=I uses 100 mhz and the minimum speed of an UHS-I bus is 50 MB/s.
UHS-I is backwards compatible with the standard cards/bus so the question still stands why class it as a class 10 and say it's a UHS-I?

So what is it now an UHS or class 10?
Does it use 100mhz data rate or 50mhz data rate?


Shall we ask B&H
