Software/Hardware RAID

[Alexy Khrabrov <braver@pobox.com>]

Now that I got all those drives spinning, I'm eager to try out 
a RAID array.  I reckon it's a better way to hedge against disk
failures than backups on tape -- even 20/40 GB dds4 or DLT is
not enough those days, and loading/rotating is tedious.

I heard an opinion that software RAID on Linux with SCSI is
"almost" as good as a hardware controller.  What is the experience
here?  Also, since I'm running LVM throughout, including the root
partition, does RAID coexist well with LVM?

But if I go the way of the hardware controller, is it better
to get a separate one, or one of those new cards from Adaptec
which say they have a Host RAID 0/1 or some such?

I'm looking at a 3 drives RAID to begin with, perhaps 4.
