In my scenario, the drives worked ok for some time, but failed en masse during high load, always one backplane failing, even after one or two of them was replaced. The errors I got was h/w and trn errors, mostly "No Device".

It didn't work at all. Any attempt at using the drive got an I/O error (I should 
have written it down), and "format" would show "Unknown drive type."

Plugging the same drive into a motherboard AHCI port worked perfectly.
