Super Simple RAID Cheat Sheet
I hate trying to remember which version of RAID does what. Maybe this will help:
| RAID Number | Why |
|---|---|
| 0 Zero | Speed, still fails. |
| 1 One | 1:1 redundant, faster read, slow writes |
| 5 Five | Stripe with parity, fast, more reliable |
| 6 Six | Like 5, but takes more disks. |
| 10 Ten or "One plus Zero" | Striping and mirroring. Speed and reliable. $$$ |
| 01 or Zero plus One | Same as 10 (as far as you care) |
Of course, if Drobo has their way none of this will matter within a few years because we'll all be using their solutions (or something like it).
