I have a Supermicro X8STi-F motherboard and would like to know if I can use SAS drives on it. I am not concerned with RAID right now, just if the drives will work. Or does the fact the motherboard is SATA imply that it only handles SATA drives?

Thank you kindly.

For SAS, the two connector segments (power Data)were merged, which makes it possible to attach a SATA drive to a SAS controller using the continuous(SAS) connector known as a SFF-8482 connector, but you cannot hook up a SAS hard drive to a SATA controller. Wikipedia reports" 3.0 Gbit/s drives may be connected to SAS backplanes, but SAS drives may not be connected to SATA backplanes" I assume this is a reference to servers that support both drives. There are signaling voltage differences for sure so even though the Wikipedia has no detailed reference, it is not possible.

Great. Thank you. – winarm Sep 22 '10 at 20:59

Shorter version: SAS on SATA Backplane = NO. SATA on SAS Backplane = Mostly YES.

SAS and SATA use different signaling voltages. Using SATA on a SAS backplane will function but the opposite will not, as a consequence of the voltage ranges.

You have it backwards, you can use SAS on SATA, but not SATA on SAS, you can buy adapters that work just for this.

Actually, you have it backwards. SAS only connects to SAS. SATA can be attached to either SATA or SAS. (I have SATA laptop drives attached to my SAS server right now) – Ricky Beam Jan 27 '14 at 21:47
