As has been discussed here a lot lately, Linux software RAID is quite
good. The only possible problem I can see is that such an array can't
be read by a Windows machine, but that doesn't matter to me at all.
Software RAID can be done with no extra hardware beyond the drive
interfaces on your motherboard. If you need more drives an
inexpensive SATA or PATA card will do fine, no need for expensive
hardware RAID controllers.
RAID5 is a good compromise between redundancy and capacity. It does
have a bit more overhead than RAID0 or RAID1 but that's really not a
problem with any machine made in the last decade. You need a minimum
of 3 same-size drives (or at least same-size partitions), so with the
drives you describe you would use both 250s and a 250GB partition on
the 350 for a total of 500GB storage. That leaves some left on the
350 for an operating system, swap, and possibly a boot partition.
Never apologize for ignorance, the only ones who should apologize are
the ones who don't want to learn.
