LSI, 3ware and Areca hardware raid controllers are capable of doing a |
8 |
background init but their performance is impacted, I can't speak on |
9 |
other controllers as I haven't used them before. I've built many |
10 |
RAID6 arrays with all three controllers - 8x 1TB and 8x 1.5TB and I'll |
11 |
usually start a foreground init and let them run overnight because it |
12 |
does take a long time. Also, RAID10 is much faster to get up and |
13 |
running because it doesn't have to calculate parity. |
