[ILUG] Raid disk query

[Brendan Minish]

Were these 'enterprise' or 'consumer' grade drives?

An issue I have seen with consumer drives in RAID is that the firmware
is a bit different in that they will spend a long time trying to recover
data from a bad block, then remap that data  

this may result in drives timing out and being kicked out of raid
