Mar 25, 2015 at 22:50 | comment | added | Mark | The maths of RAID 5 degraded operation are easy: it's just a bunch of XORs, which a modern CPU should be able to do at a rate of GB/s. The slowdown during degraded operation comes from accumulating the data: in order to reconstruct what was on the failed disk, you need to read from every other disk in the array. | |
