260GB is a peculiar size.


CFeB cards are generally powers of two sizes, like 128GB, 256GB (like you'd see in SD cards).


CFeA cards from Sony have been multiples of 80GB - not explained, but possibly some level of over-provisioning (like 128GB of flash capacity limited to using 80GB to allow plenty of room for wear levelling). Some other brands have followed Sony'd lead on this (Lexar, for example). Or maybe it uses 5 banks of 16GB chips - there has been varied speculation on the reason for the odd size


But 260GB doesn't fit. Not even the multi-bank theory.


When I saw 260GB in the thread title. I wondered if it was a typo for 160GB, but you repeated the size in the text.
