As I just RAID-ed my main system, and have the info fresh... |
| 10 |
|
| 11 |
If the capacity is there, go RAID6 (dual parity RAID5, so two drives can |
| 12 |
drop out without the thing dieing) with a hot-spare as well, so |
| 13 |
threex146GB usable. |
| 14 |
|
| 15 |
In any case, I'd go RAID6 with no hot-spare over RAID5 with a hot-spare, |
| 16 |
as it's effectively the same thing, only with RAID6, you can lose two at |
| 17 |
once without dieing, instead of only one -- and you hope the second waits |
| 18 |
to die at least until the hot-spare gets synced. |
| 19 |
|
| 20 |
This of course assumes software RAID, as RAID6 is certainly a kernel |
| 21 |
option. If it's hardware RAID, you of course go with the capacities the |
| 22 |
hardware supplies, and I'd guess RAID6 is a less common option, certainly |
| 23 |
less commonly known. |
