Can Someone Explain SAS To Me?


Recommended Posts

I have 4 WD Red drives in my my setup currently. 1x 8TB and 3x 4TB. I’m looking to get an HBA but I read a lot of users use SAS controllers and I don’t know what hardware is required for this. Can a SAS controller be used in my setup? If so do I need to change any bios settings?

Yes, you can use a SATA drive with a SAS controller.  You just need the appropriate forward breakout cables to connect them.

 

No BIOS changes are required.  Just look for a HBA (recommended is LSI based) that's already in IT mode (instead of IR mode), although this can be changed with flashing it's BIOS.

 

But, you're not going to see any advantages over using the already present SATA ports on the motherboard, and if you only need one or two more ports you may be better off getting a ASM1061 SATA card.
