They're actually workstations so I don't think I should neglect the performance aspect.

How much is the CF adapter? That would narrow the gap, although maybe not considering a 2.5" -> 3.5" adapter. Yeah, it looks like ~$80 for a 16GB Super Talent drive. This one for ~$120 is 32GB and is said to have no stuttering (apparently because of its internal Indilinx controller): http://www.newegg.com/Product/Product.aspx?Item=3DN82E16820609392 Anyway, the point of all this is to prevent an HD failure from stopping the system. An SSD is much safer, right? - Grant
