You can presumably fit any device that you wish to fit, so long as it meets
the SATA spec. WD Red drives are designed for NAS use, though: that's their
whole point. They're not drives that you'd stick in your desktop machine.
The last time that I checked, the price of SSDs wasn't that inviting once
you got above "desktop boot drive" sizes, so using them as NAS storage
wasn't a sensible option. Checking on CCL now, they're still around three
times the price of WD Red drives of equivalent size, and WD Red are in turn
still around 50% more than an equivalent WD Blue "desktop" drive.
Then factor in the desirability of RAIDing the drives for reliability, and
the costs have suddenly gone up again. The elderly, custom-built 2TB RAIDed
and then mirrored setup that I have here contains around £225 of drives at
today's prices; it would be close to £600 if I went down the SSD route.
So yes, you /can/ use SSDs in a NAS, but money would need to be of no

That, and the fact that you're not running an OS off them, so response times
are much less critical than for the drive that you boot Windows, Linux (or
even RISC OS) off.
