Sounds like a work/office computer? Or a warranty replacement? If it's a personal computer then do yourself a favor and get an SSD or 7200RPM HDD.

My bitch: my SSD has been giving me trouble again lately. Randomly hangs, particularly when Firefox is open. Probably related to the Marvell 6GB controller, but the last time I had to mess with this issue, switching to the Intel controller on the motherboard made it worse.
