Looks like a great deal!
The only question that I have for those who have used similar storage device is:
Can you download some files from laptop to this storage drive, then plug in the SD card, and move the files to the SD card?
I am thinking to store some movies on the storage drive so when I am out I can easily access them via the SD card... Possible?
