Re: Some sympathy -but not a lot
I've always wondered why there isn't business practice to replace half the drives in RAID 10 and move them over to a fresh server with more brand new drives. Then you get half your drives (make sure each is one half of a mirrored pair) with a remaining MTBF to the others and therefore reduce the chances of dual failure.
Doing this could allow you to use cheap low endurance SSDs rather than high end drives (HP Drives High Endurance 800GB SSD = £2700 ex VAT each!) with less overall risk even if it does require more swapping over the years. If you have spare room in the chassis to keep hot spare then so much the better.
