Why may I ask are you advocating such a rediculously fast hard drive for such a simple task?
Those X15s are really meant for things like data mining, 1,000,000+ SKU databases, etc.

Why do you feel the need to recommend such a rediculously unneeded disk subsystem and in the very same sentence, say "32-64 MB RAM?"
