vb.org Archive - View Single Post - 10k SATA vs 15k SCSI Hard Disks...

I scanned over the article to the end results so I may have missed something. I did a lot of research before having my new 2x 270 Opteron server custom made with 15k SAS drives, RAID 1 & RAID 10 drive arrays, etc. I had a lot of people telling me to go with the Raptor 10k SATA drives because they were "just as fast" as SCSI but after a lot of research that just isn't true in a heavy data base environment. SCSI or SAS drives have a lot better I/O than SATA.

I would be willing to use fast SATA drives for future web servers but for my database server I won't use anything but SCSI or SAS.
