md raid 1 has never given me a problem no matter how hard i hammer it, just
raid 5. so you should be fine. good luck!

Jason,
Thanks for the info.... Once I make a copy of everything then I may
just boot it up and let it work the bugs out... I just don't want to
loose all my e-mail and files.
As far as software raid, I'm not going to do RAID 5. I want to move to
a simpler setup using simply mirroring. Right now I have 4 x 60 GB
drives (well the replacement is an 80GB drive) for a total of 180 GB
of space.
I'd like to move to 2 x 400 or 2 x 500. Two drives and more than
double the disk space. I guess since most of my hardware is in the 5+
years old category I want to move to a more "mobile" solution in case
the 3ware card does fail.

i got a bunch of those 3ware warnings on my arrays (9500 8 port) when i
first assembled them too, once it initialized it was fine and has been
running flawlessly ever since (about 8 months).
also fwiw, i bought a 1u supermicro server this week (5013cmt) w/ 4x sata
disks in it. they work fine individually, even under high simultaneous
throughput to multiple disks. but it locks up hard if i create a md
raid 5
device and put it under any significant load (os was fc5). sometimes it
would even crash during mkfs.ext3. so software raid isn't necessarily a
panacea either.
