It's software and speed overwhelmed me when I first used it. Now I think it's slow. lol
Actually, I am thinking of replacing my 200GB WD Special Edition Caviar HD with a RAID 0 setup of 72GB WD Raptor HDs. That should take care of the speed issues (all due to the sluggish 20Mbps transfer from the HD). Then using the 200GB drive for weekly backups to negogiate the increased risk of data loss caused by RAID 0. Of course it would take me a while to procure the funds required to do so.
