Used hardware can fail. New hardware can fail.
A failure is a failure.
I think I saw it said here that if one's data
were important enough that a RAID was being
considered then the purchase of used equipment
should somehow be ruled out, but I must have
missed some crucial piece of that argumen

That is incorrect. It is quite possible to have solid-state components
which are marginal. Such components may have intermittent problems, or may
simply fail early. I have certainly se

I ordered a Woody disk last night for $5.95. Only a single disk, but
supposed to be enough to get started, and you can get the rest over

What distro do you want to use? If you want to use Debian (which I
highly recommend), I would go for woody instead of potato. Debian
potato is too dated right now. You'

That is likely because you should be trying to setup the array before you
setup Linux. :-)
The idea is, you use a controller-specific utility (either booted from
flop
If it's a hardware RAID, you just use the RAID firmware to create
logical(?) drives out of the array. Once that's done, RH or
distro-of-choice will load in the drivers and let you access each
logical drive just like an IDE or SCSI drive - partition, format and
away you go.
IIRC, there's a limit
