What's the total advertised/marked capacity?
Reason for question - lots of cheap far eastern con-artists are selling (seemingly) high capacity micro SDs via Amazon etc, which 'look' like they have the stated capacity - until you try filling them up, and find that 500Gb card is only 128gb.
Files appear to transfer, but when you open the card - they aint there.
They cleverly format them so that capacity shows (for a 500gb) - around 480Gb
