View Full Version : old scsi vs sata raid
10-10-03, 02:43 PM
Setting up a server over here and I wanted to know what would be the fastest for the os and programs. 2 MAXTOR 80GB 7200RPM SERIAL ATA150 8mb cache in stripe 0, 2 old IBM SCSI drives...specs:(http://www.nextag.com/serv/main/buyer/ProductM.jsp?kw=IBM_STORAGE_HARD_DRIVE&product=10597382&pdir=0&click=n&node=&core=2&page=1&lgnode=&lgsearch=ibm_dnes-309170) in stripe 0, or one raptor drive...maybe two rapter in stripe 0...but that would be pushing it in price. Since I already have the SATA and SCSI drives.

I would say the 2 raptors would be the best, but the maxtors would probally be the 2nd choice for me with what you have.
But if you want to upgrade the array over time, I would pick scsi.
What the server will be used for makes a difference for configurations. The best IO levels will be a single Raptor and the best STR will be the pair of Raptors in RAID-0. If the server requires close to continuous uptime, stay away fom RAID-0 due to the lack of redundency. The Maxtor's would be the next choice. Those SCSI drives dead last in this case. They're 7200RPM U2W drives and too obsolete for high speed operation. 7.0ms seeks aren't too bad, but at 9GB they're almost not worth the power consumption.
