On the other side of things, I've owned 3 X25-M's. A first gen that died in 9 months, a second gen (RMA replacement) that just started acting weird and corrupting things last month (was about 15 months old and was in a RAID 0 array with another X25M but I undid the array and began using the better of the two X25M's). Needless to say I use Dropbox, Time Machine and Carbon Copy Cloner very often.
