Summary: This is a great product - it works great (I've had good reliability from Kingston and SanDisk brand SD cards and mediocre reliability from Patriot cards. Unfortunately, the transfer speed on this memory card is not very fast. It takes several minutes to copy a couple GB to the drive. However, for most of my uses with this card, I'm not writing too much data to the drive all the time. I'd recommend a larger/faster card to be used for a digital camera, though.
