I have been tinkering around with freenas for a couple of years now and I tend to replace my drives when I see a lot of errors or prefail warnings. I am just kind of curious if I have been replacing too early or if it is in good practice to replace as soon as possible issues come up. I have lost all data before and I have vowed to never let it happen again. So yah, just like to know what you guys think on the whole drive replacement.
( I know it depends a lot on brand/size so the main goal here would to be to find out if people replace at first sign of prefail or if they hold off until there are performance issues. )
Edit:
Types of S.M.A.R.T errors that concern me would be:
-high raw read errors
-high spin up time
-reallocated sectors
-spin retry count
-min/max temperature
