[kwlug-disc] Bundling HD's. LVM vs mdadm vs ???

I'm running out of backup space, so I'm probably going to buy a larger
drive, and move a current drive into another computer - expecting to
bundle it with the drive already there into a single logical
presentation. (Add 4TB, move 2TB -> 2TB + 2TB = 4TB.)
I don't 'do' RAID (at least at home, where high availability isn't an
issue), and mistrust striping - lose 1 drive, both be gone. I prefer to
say 'this' amount of space for 'this' purpose, so when I run out of
space I'm aware of and address the issue.
(Presumably a worst case scenario for such bundling upon failure is
losing one file - the one that crosses physical drives. Correct, even
I've known for some time LVM is out there, just never needed it. There's
also mdadm ('LINEAR') [Which I gather LVM calls upon.]
Any particular pros / cons / preferences / suggestions / thoughts for
bundling multiple drives into a single logical drive?
I'm guessing the only reasonable drive out there at the moment is a WD
Black - (5 yr warranty, 7200, SATA3, availability / stock levels).
