Thanks... |

But... RAID read/writes under normal operating conditions has nothing |
| 12 |
whatsoever to do with REBUILD speeds/times. |

Again, the reason I'm interested in this is, if the rebuild times are |
| 15 |
'blindingly fast' (as compared to the times for SATA or even fast SAS |
| 16 |
drives - ie, 1 hour vs your 10 hours)), then maybe a RAID6 with SSDs is |
| 17 |
back in the realm of doable, since you don't lose 50% of available |
| 18 |
storage with RAID6... |
