Because they're much more expensive on a $/GB basis than equivalent
3.5'' drives (and much slower). Also, you can get 4TB 3.5'' drives
today, whereas 2.5'' maxes out at half that.

200W running for 8760 hours (1 year) comes to around $200 (at
$0.12/kWh). That IcyBox consumes less than 1/4 of that, so if you're
examining your finances so carefully, factor in an extra $300 over 2
years you'll spend on the MSA50.

And a small box with a power supply and pass-through connectors somehow
doesn't work? You know you can get SFF-8088 to individual SATA/SAS
fanout cables, right? And once you stuff the HP MSA50 full of 1TB hard
drives, it's not expandable anymore. And if you're going to be replacing
hard drives in the MSA50, you can do the same in the IcyBox.

This is used outdated 3G SAS kit you're showing, so it's pretty clear
it'd be much cheaper.

Overall I think you're trying to save money on entirely the wrong
things. Get a few good high-capacity disks and a low-power enclosure and
don't worry about buying a SAS HBA (or if you do, buy one which doesn't
limit you to 2TB per drive).
