just go *somewhere* on each drive.
In the end, RAID produces a block device that you then run a filesystem

hence asking here.
To put it differently:
If I wanted to upgrade to build 124, say, or 130, how would I do that?
What would I type?
And the other half of the question, what's the best stable built around
this week?

lockin.
I've seen people down extra days while locked-in parts are shipped to
them; the parts were essentially identical to what you could buy that day
at retail locally, but the locally-available version wouldn't work.

It works great for me personally -- I'm using the software with other
people's hardware, for free.
But why should people who need a lot of storage pay proportionally more?
I don't get that, that's grossly wrong.

uy, neither
management nor marketing nor hardware engineering.
Also, if they really are charging 10x, then they can easily cut prices to
compete with any upstarts, a fact that potential investors would take note
of.

I paid $1500 for, come to think of it!)

two small partitions and a data pool from the two large partitions,
thus keeping data and root separate and still providing redundancy to
both, within the two drive constraint.

check the length first, though. And they're listed on
Amazon. (Supermicro either doesn't, or at least makes it very hard, to
buy direct from their web site, or even check a price.)
(This is a big Chenbro case, I think it's really a rack 4u system being
used as a tower.)

rom the same bad batch!
Google is working heavily with the philosophy that things WILL fail, so
they plan for it, and have enough redundance to survive it -- and then
save lots of money by not paying for premium components. I like that
approach.

Okay, so this SuperMicro AOC-USAS-L8i is an "SAS" card? I've never done SAS;
is it essentially a controller as flexible as SCSI that then talks to SATA
disks out the back?
Amazon seems to be the only obvious place to buy it (Newegg and Tiger Direct
have nothing).
And do I understand that
as well. However, the namespace doesn't seem to have any
possibility of overlapping the names of the disks in hot-swap SATA
enclosures, so it can't overwrite any of them by any mechanism I can find.

6 or 8 hot-swap bays and enough controllers gives me relatively few
interesting choices. 6: 2 three-way, or three two-way; 8: four two-way,
or...still only 2 three-way. I don't think double redundancy is worth
much to me in this
