low power raid1?

[wkearney99]

I've got an atom-based board used for a mail server and I'd like to find the lowest power consumption hardware RAID card for it. Just two drives is all that's needed. No, the motherboard Intel fake raid is not a solution for this particular situation.

It's difficult to run down which cards are lowest in power consumption for something as simple as this.

I'd say your best bet is using a modern card as they have the newest smallest die size and most efficient power usage.

Uses a maximum of 9W and will do RAID 1, 0, or 10

The linked card is not a hardware raid controller, just an SAS HBA. All RAID functions are done in software by the host CPU (aka fakeraid). If you want real hardware raid you have to get at least a 9260-4i or a comparable OEM controller. The IBM M5014 is often suggested here because of its low price.

That's the challenge, either it's fake RAID (which this particular motherboard already has via an Intel chipset) or it's overkill. There doesn't seem to be an in-between.
