hard drive comparison (dual raid-0 vs. single w/databurst cache)
-
Was hoping the hardware gurus could provide some insight into this comparison. dual 15,000rpm drives setup with raid-0 vs single SATA 10,000rpm drive with databurst cache These will be used on a development machine for code compilation.

I doubt that RAID-0 of two 15000 rpm drive could be beat by a single drive.

Well, I figured the dual raid-0 drives would be better. What I'm wondering, though, is how much better. i.e., if its only a minor improvement, it might not be worth the extra money to get the dual raid-0 drives.

Yours 15000 rpm drive is a WD Raptor, isn't it? Anyways, a quick googling resulted in this review. http://www.pcstats.com/articleview.cfm?articleid=1746&page=1[^] My bad, Raptors come in 10000 RMP only. You must be referring to SCSI drives, right? Here is a good place to read reviews http://www.storagereview.com/[^].

Depending on the drive... but generally single SCSI U320 single 15k runs at 87 MB/s, a RAID0 pulls about 140+MB/s. My fastest RAID0 was a 4 disk RAID0 of 15K U320 drives. It's average speed was 280 MB/s, and was a hardware RAID0. A single 10k SATA runs at about 78 MB/s with RAID0 starting at 120 MB/s and going up.
