A hard drive has two states: dead and dying

My oldest hard drive is giving its last death rattle in the form of ever more common clicks. It is still working… but I’m pretty sure it’s days are numbered.

I’ve backed up all the data from the clicker drive and now started an experiment. I’ve placed this drive and another semi-clicker into a ReFS mirrored storage space on my Windows 8 desktop. Write performance immediately tanked from 140MBps to 45MBps similar to what people have complained about before but otherwise I haven’t noticed any major problems.

Will my data survive? I’m planning on adding another working drive to the array just to hedge my bets…
