[mythtv-users] X using way too much CPU?

[nick]

IDE Raid doesn't do anything for write performance.. If anything it'll
slow things down (if you do a stripe, then it might be faster, but you
still want to write out parity, which causes a hit again, so it balances
out).  Reading tends to be faster, however.

Cheers,
Aaron

That was my suscpicion.  I figured parralelling your drive read/writes
would speed things up as your head doesn't have to beat itself up trying
to allocate data.  What about IDE Raid?  Anybody using this setup? If
so, how is that going for ya?

I was totally considering getting 2 80gig drives and striping them into
1 160gig partition.. this would allow for a lot of performance gain...
Maybe I'll venture into 2 200gig drives.. man.. 400gigs.. drool..
anyways.
