Yea, but do you have (2) of 'em??? The MP's are a little more
internally optimized then the XP, from what I read on
tomshardware.com, and TMPGenc can max both of 'em...

Well, I have dual Ultra160 on the motherboard, it's non-raid. That
doesn't stop me from mongospeed in Linux using software raid, but
that doesn't help me much in Win2K where I do my video schtuff...

I was getting about 60-65 MByte/sec w/3 9Gig drives striped under
linux, but methinks that was a limitation of the software raid, as
the CPU wasn't quite taxed... I'd like to see what software vs.
hardware raid would do with a drive setup like yours...

Just 1G? I have the same monetary limiting factors as you, but my
mobo will let me go to 3.5G when I want to... :-)

Yea, if only we could get that poor little 53Mhz PPC in the tivo to
push a gigabit adapter... ;-)
Considering that (at least for what I do with my setup) HD speed
isn't the limiting factor, I dunno if I'd trade the dual CPU setup
for hardware raid... even with my 7200 RPM IDE drive, the kernel CPU
usage rarely & barely hits 10% on either CPU, with an average of
about 3%... Offshifting 3-5% HD load versus bumping to 3.46Ghz (a
pair of 2100+MPs would definately make my mouth water) methinks I'd
allocate the $$$ for the latter first.
Altho you definately did give my drive envy... :-)
