I use used and refurbished Seagate Barracuda 180s. If you find them for
$50 each on eBay, that's a good deal for that particular model of drive,
and it costs $.28 per gigabyte. Search for st1181677lcv on eBay, and
right now I found a lot of ten of these for $380, which comes to $.21
per gigabyte, which is roughly equivalent with today's large SATA drives.
Both my BE and my file server each have 6 of these in a RAID5. As long
as you keep the drives cool, even used have been reliable for me.
I also do not keep my BE and file server in my living room or bedroom -
they live in my nice cold basement, where I can't hear them and their
I like SCSI - a lot. But I don't recommend it if you are not the
patient type. It takes a bit of effort to understand. SCSI is a
commitment in both equipment and learning, but once setup, they are just
as much set-it-and-forget-it as any other disk technology.

My BE is a dual 600Mhz P3 with 576MB of RAM - it comm flags recordings
from my PVR-350 in 2-3 minutes behind real-time. I don't transcode

I don't have any HD recording devices, but I'm planning on adding a
HD-5500 in the next month or two, and I'll let you know how it goes.
