vfat32/MSDOSFS is going to be the most supported, seeing as I can
mount these types of filesystems on just about every OS out there.
Regarding speed, there's a pretty big tradeoff, but even if it reduces
drive I/O by %50, you're still above the speed of a 10/100 NIC, and
certainly above the speed an MP3 streams at. (You're right at the
limit, for DVD Video) In short, yes, it will be slower, but for the
purposes of storing MP3s, and whatnot, the speed tradeoff is
inconsequencial(sp), and it beats loosing everything every once in
awhile.
