I have 2 Sata SAS Seagate cheetah 15k.7 300gb, I was wondering if these would work with my ASUS with 6gb sata ports. I have the SAS cables that connect to the drives, but when I hook them up they don't spin up, they are not detected in the BIOS. Am I missing something? someone please help?
As others have pointed out, SAS drives are not compatible with SATA controllers. Despite having identical connectors and electrical configurations, SAS uses the SCSI command set with SATA uses the ATA command set. SAS controllers have compatibility for SATAII drives but no SATA II/III controllers have compatibility for SAS drives
Some time ago, I experimented with scsi and 15k drives.
They worked, but really it was not worth the hassle. I noticed no improved performance.
The value of 15k is shorter random access times, which is good for the os. It has no effect on data transfer rates.
Modern sata drives will be better for the desktop user, and if you really want performance, get a SSD.
