[mythtv-users] anyone using software RAID 5 for 1 terabyte +

I have 5 250 GB hard drives that I've tried configuring a couple
different ways. The first set-up was all 5 in a 1 TB Raid5 array.
Unfortunately, in the first setup configuration (all 5 drives in Raid5
were used for /, /home, /usr, and /var as well as my mythtv directory)
I noticed that whenever the box was recording something while I was
watching something else, playback was jerky.
I have since reconfigured, and have /, /home, /usr, and /var on one
drive, and used the other 4 hard drives for a 750 GB Raid5 array just
for mythtv. In this configuration, I haven't had any problems at all.
I know others have used all 5 hard drives with no problem -- just not
me. It's possible that my motherboard is to blame (I wasn't using a
sata or raid card, just 5 hard drives plugged into the motherboard
with mdadm) or the fact that one of my five drives was IDE, and the
others were SATA.
I was concerned about upgradeability myself. So far, 750 GB seems to
be treating me just fine. ;) And I guess by the time I'll need to
upgrade, hard drives will be considerably cheaper -- I can always
replace each of the 250 GB drives with 500 GB drives and double the
capacity.
