I also have got a box running plain in-kernel software raid level 1 (with |
| 9 |
2x80GB EIDE disks), and I'm very happy with it also. I manage it with |
| 10 |
mdadm, and, after the initial setup and the mandatory tests (simulated |
| 11 |
failure, etc.) it runs very smoothly and you can really forget about it. |

Just follow the directions in the software-raid howto. If you want to |
| 13 |
have your / on a software raid, things are a little more complex (but |
| 14 |
not too much). |
| 15 |
If you have many more reads than writes on your raid array, eg in a web |
| 16 |
server, software raid (expecially level 1 and 5) usually performs very |
| 17 |
well, since partial reads are performed in parallel (if you set up |
| 18 |
things carefully). |
| 19 |
IIRC you have only two disks, so raid 1 or 0 are your only choices (be |
| 20 |
sure to backup regularly if you use plain raid 0 since it has no |
| 21 |
redundancy). |
