I work mostly with CF cards (NEF files, on average, 20 MB).
The introduction of this card is "tag" down, unlike my old drive. So do not force it if your card seems to resist ..... (this is also shown in the doc!)
This drive is backwards compatible. Works even if you have only a USB2 connector (not tested).
On the debit side, I have just completed the installation of a new machine. Then everything seems much faster !!!!!!
Very satisfied with my purchase
