I'd suggest a Momentus XT drive. 7200 RPM Large Cache & 4 Gb SSD Cache
I'm with 'ya - ever since I asked about the 500GB XT, 2--err--3yrs ago here on BBR/DSLR, I've bought 2 more for other desktops and 1 for a laptop. On MY (not my wifes or kids), I still use my OS on the OCZ Vertex2 and my data goes on the XT. Love them. -- That's "MISTER"Kafir to you.
