They defrag very fast!
I have 4 PC's here
1 has a SATA Raptor 74gig and a SATA Seagate Barracuda 80gig
1 has a Maxtor EIDE 120 gig
1 has a Maxtor EDIE 60 gig
1 has a SATA 160gig Barracuda
Both the Maxtors, one of which get used heavily for photo's and film and editing and stuff on an old P4 2.0, and the other is in an nForce2 gaming SFF..... both defrag MUCH faster than my other drives.
Whats THAT all about?
