several partitions vs several physical discs? Tags: Hard Drives NAS / RAID Storage Last response: December 24, 2007 1:17 PM in Storage Share januszian December 24, 2007 11:17:40 AM Which one is faster: - Two separate RAID 0 arrays with 4 physical discs (4x160 gb) - One RAID 0 array with 2 discs and two partitions (2x320 gb) Assuming that the end result from both is C: 320 GB and D: 320 GB. (and that all the harddrives have the same specs...)

Why you want absolutely 2 drive letter? May be you can look at RAID-5? What will be your backup procedure? I would choose two RAID-0 and use the second one as a backup (if you don't have an on-line backup or external backup). If speed is only matter, I would try both configuration and do benchmark. I would also look at Raptor 150. zenmaster December 24, 2007 1:17:30 PM LoneEagle said: I would choose two RAID-0 and use the second one as a backup (if you don't have an on-line backup or external backup).
