I've been running a RAID 0 with two WD Raptor 36 GB drives for the past 4
years.  Neither has gone down and I've never lost anything.  Sure, it could
happen, but today's hard drives can withstand a lot.  I do keep all my
installation programs on an external hard drive (partly for portability, but
mostly for a backup) and that drive has failed me before (which is why I
have a backup for the backup).

Regardless, a raid 5 would give you the peace of mind that if one drive
failed, you'd be okay.  My dilemma with a card is that it's hard to find an
onboard raid 5 chip.  The card is still going to run through the PCI bus, so
unless you pick up an PCIx board, you'll have limited bandwidth.  I ran a
raid card (intel processor, 16 mb ram, can't remember the manufacturer - DLC
or DCI or something like that) with 5 scsi hdds on it.  It was dog-slow,
unless I did disk-to-disk operations (like copying or moving files, which
the controller card took care of).

i agree w/ gabe - go software raid5 for something like this.  

the only thing hardware raid5 will give you is a battery backed write cache
for fast writes, which software can never give you (which is why software
raid5 can be unsafe for database applications unless you writes are sync'd,
which is slow like the lazy dog instead of fast like the quick rabbit.)

of course, when you say "I am not too worried about loosing some files" then
just do a raid0, but know that you *will* be hosed if you lose one disk.
