I currently have 4 x 2TB WD green drives in my fileserver, and I'm thinking about adding more. The problem is that I have exhausted the onboard sata ports, and need to add a very low power pci-e hba (the FUSION350-A-E has an open ended x4 pci-e).
You can see system specs in my signature (BOFH).
So specifically I'm looking to get the lowest consuming 4+ port HBA possible. Wondering if anyone have some power consumption figures regarding different sata HBA's?Possible HBA's:
- Adaptec 1405, 4 port (official specs 4.62W typical; 1.4A @ 3.3V)
- Intel SASUC8I, 8 port (no specs I could find)
- IBM M1015, 8 port (no specs I could find)
- LSI SAS 9211-8i, 8 port (7W according to website)
I already have a 2-port Adaptec 1220SA. This one is just under 2W (tested in my server, official specs 0.9 amps@ 3.3V).
I hope someone can help, I'm trying very much to keep the power consumption low. Any power hungry controller will easily add 50% to the idle power consumption of my machine
