I am sure you know the common things that can increase your hard drives
life and performance:
The rust hard drives I have seen the most failures with are: (I recommend
(Not The server drives)
The rust hard drives I recommend the most are:
WD Black 7200rpm or better
Seagate 7200pm or better
(Not Red, Blue, Green, Purple)
If you are doing the moose distribute setup
You could always choose two different brands/types
if you want to know more specific things about which hard drive failures.
Check out this from backblaze, I am sure there's more around. Which is one
Benjamin sent around ages ago.
