I ended up with one in my server because the Lian-Li PC-Q08 has a space for a 2.5" HDD and while I'd intended on using a 250GB notebook HDD. the HDD started having problems. The only other 2.5" device I had "lying around" was a 64GB SSD. I could take it out and clone to a HDD if I found a deal on a 2.5" drive but I figure why bother. It's working. I also wanted a separate drive for my OS since my ultimate plan is not to stick with the WHS2011.
I did notice one big difference in speed between the HDD and the SSD was Remote Desktop comes up much faster with the SSD than the HDD did. Using the Dashboard through RD also comes up much faster.
