1. What does that "R" in "RAID" stand for again?
2. Good backups are your friend.
3. With the purchase of an enclosure, I now have a home-made external hard drive.

I love my RAID 0... it just always makes me a little nervous.
I'll probably buy another drive next time I do a scratch/reload and go RAID 1.

What's cool is that we had 2 500GB drives in RAID 0 -> 1TB. Now, 1.5 years later, we've got 2 1.5TB drives in RAID 1. 50% more space, and no worries.
I guess it might be slower, but whatever.
I now also have an extra 500GB external drive for backups (had one already).

We've got 6x750GB in RAID 5 and 2x500GB in RAID 1 and 2x1TB in RAID 0.
Although, I havent actually rebuilt the 6x750, so I was thinking of doing RAID 10.

Wait... RAID 1 is mirroring, isn't it. That isn't what I meant.
Which one is 3 drives, striped with a parity drive for both speed and backup? RAID 10?

I was going to set up Raid.. but It was too much effort, so I didn't.
I have two drives in the trays, and only one of them actually plugged in.
I'm lazy.

iirc, that's RAID 5. And it's 3 or more.

RAID 5 is a single parity drive, 3 drive minimum. It's faster than a single drive, but slower than RAID 0 and RAID 10 due to the additional calculations on writes:
Drive ops: (all are 1 op per read)
RAID 0: 1 per write (striping)
RAID 1: 2 per write (mirroring, 2 drives)
RAID 5: 4 per write (parity, 3 or more drives)
RAID 6: 5 per write (dual parity, 4 or more drives)
RAID 10: 2 per write (striping and mirroring, 4 or more drives)
