[mythtv-users] ATA RAID Question

[malcolm]

You really don't need such powerful drives for mythtv.  I have a PVR-350
(using tv out) and a PVR-250.  I can capture two shows at once and view a
pre-recorded show (or watch one of the shows currently been recorded) at the
same time and my ata33 5400rpm drive (not 133 but just 33) humms right along
with not to much stress.

If you think about it the PVR-350 or 250 with Myth's default settings writes
2.2Gigs an hour.  So recording 2 shows at once: Do you think your ata33
drive can handle writing 4.4Gigs in an hour?  Sure of course it can.

If you really want raid though we always use 3ware escalade cards at work.
Excellent cards and as of recent their open source drivers are included in
the kernel which makes them real nice to use.

Later
Malcolm
