The times can be very useful here (though you have to translate them from power-on hours to actual time).
Also, after you replace the disks, I suggest setting up a maintenance schedule (settings wheel of the volume). You can schedule
- defrag
- balance
- scrub
- disk test
Personally I run one of these each month (cyclling through all 4 3X a year).
Definitely wait until you have healthy disks installed though.

To be honest, I'll just take a hammer to the old disks, not really worried about the timings, etc. I'm hoping this is the cause of the bizarre issues we've been experiencing.
Yes I have the defrag and scrub running once a month. Didn't know about the balance until I saw that setting yesterday.
We're trying to avoid using the NAS until the disks arrive in the next hour or so. I did a smart check on our web servers just in case and one of those has a high error rate, so We're getting that one replaced too.
I might grab another readynas and install it at home as a spare and mirror this one to it as a nice offsite backup.
