SATA has faster transfer speeds than IDE...but can be a chore to setup sometimes.
All IDE manufacturers make decent drives so don't get caught up in the WD vs. Maxtor vs. Seagate arguments ...they are a waste of time.
Seagate just acquired Maxtor but are also the only manufacturer offering 5 year warranties if that's important...
Basically when i buy HDD's i just try to get the most bang for my buck.
patio. 8-)
p.s. and always remember GX1_Man's maxim....all HDD's fail eventually. Devise a regular backup strategy.
