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

You would think so, wouldn't you? However, one of my Netgear

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

because I don't see how owning a new (versus

warranty why can't you get a replacement

Precisely my point. Although 2 years is a long time for a design flaw to

No, you will still need the driver support in the kernel. Once

highly recommend), I would go for woody instead of potato. Debian
potato is too dated right now. You'll

If the used controller you bought from some
guy on eBay fails, or starts acting flakey, it doesn't matter what
RAID level you're running, or how good your disks are, you'll probably
lose data. With controllers available so cheaply new with a warranty,
I can't imagine that the cost savings

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

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
