I have a Dell 690 Workstation. I have mulitple drives installed now, including a SAS pair in RAID 0 (270GB), a SATA SSD and a 1.8TB SATA Barracuda XT. In adding the last drive I noticed the arangement of the HDD connectors on the motherboard. 3 labeled SATA_0, SATA_1 and SATA_2, then 4 labeled HDD_0, HDD_1, HDD_2 and HDD_3.
When I read the manual on these the ones labeled SATA_x are definitely for SATA drives only. However the ones labeled HDD_x are either SATA or SAS.
My question is, are the SATA_x connectors optimized for SATA and therefore a faster channel, or will all 7 of these connectors be controled the same way (possibly even the same controller HW) and so any mix of SATA and SAS drives on the HDD_x connectors will work the same? Also, I believe the HDD_x connector bank may be the only place I can create a RAID setup for any SATA drives as I see no option to create a RAID under the BIOS for SATA only connectors.
Trying to optimize where I mix in the SATA drives and possibly another into a RAID. I have no choice but to leave the SAS drives where they are obviously.
