|If I made regular backups then I's use my hardware raid controller to create a striped array. If I didn't have a hardware based raid then I wouldn't fool with it at all. |
Raid arrays don't generally wear out drives or damage then as such nor do they create data loss. This does make some assumptions.
I just don't get your reasons for this odd setup. Raid 0+1 may be a solution but takes a lot of room for a small gain.
1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.
