I need a SAS Expander card but which specs x16 vs x8 and 12G vs 6Gb/s

by cemster . Updated 4 years, 8 months ago

Hi,
I found myself in need of a SAS expander card to accommodate my Z590 series motherboard that I am running an audio workstation with. Which only comes with 6 HDD Bays.

I am not going to RAID. I need 6 ports. So they are gonna be 12 total with my MOBO. They should support at least 8 TB drives, and they are all going to be needed at any given moment in my workflow.

But most of the cards I found Googling are either: x1, x2, x4, or Lanes are not mentioned at all.

And then there is 6Gb/s versus 12Gb/s cards… I’ve heard that the performance is %30 better with the latter.

I am perplexed about which specs I should chase. Which would be good enough? Obviously, I’d like a fast and reliable card.

So help on the subject and also maybe some specific card suggestions would be appreciated.
