If you really have a BUNCH, get a SAS disk expander. I have 2; one 2.5" with 25 slots, and one 3.5" with 16 slots. The 2.5" all loaded (I have 20*600GB + 5*3.8TB in) uses about 50W in normal usage. It is a bit noisy of course, but not *that bad*... Also cheap s/h. You just need a HBA card. The 3.5 I turn on to do whole backup, it has 3TB disk in there and thats *largely* enough to image all my stuff several times, I only turn it on via a PDU when I need it.

If you only have like 10 ish, in my workstation I use a 8 bay SAS 2.5" "icybox" that fits in 2*5.25" chassis bay... In that machine I use a Dell Perc raid card and run 8*1.8TB 12Gbs disks for around 10TB total storage in there.

SAS disks are cheap as chips refurbed, super reliable.
 
That only deals with the data side though, power is more tricky.

Was more wondering if anyone has done similar or use a NAS with them in

Normally the enclosure has a backplane that provides power. I did have some internal SAS cables years ago that had separate power connectors. Assuming your NAS doesn't natively support SAS?

Are these SSDs? 2 watts per drive seems awfully low for "normal" usage, if they weren't SSD. I'd expect them to be using about that for complete idle.

Yes all SSDs... I have the whole thing off a metered PDU so I can tell it uses .2A when on. Not all of them 100% write, just idling along with light usage.
