The prior drives are 4 x Samsung Spinpoint F1s (HD103UJ). I have liked them quite a bit, and since they are 7200RPM drives yet have been quite quiet (at least for their time), it's sad to see them go. Here's how an older HD103UJ has been performing on my system: What drives do you recommend? This will be in a RAID-0 setup, and of course, silence is golden.

I have currently narrowed it down to the Hitachi Deskstar 5K3000 and the Seagate Barracuda Green ST2000DL003. Both are ~5900RPM green drives. I'm open to other options, including 7200RPM drives (provided that they are at least as quiet as the HD103UJ).
