August 9, 201213 yr My Parity disk is showing a Smart History Warning for Power_On_Hours of 36,765. Does not show any errors. Does this just mean drive is getting old?
August 9, 201213 yr I would assume so, after all, the drive has been running for a minimum of 4 years (if non-stop)
August 9, 201213 yr Author Just looking for a recommendation, would you replace now or wait for some other indication of failure?
August 9, 201213 yr Just looking for a recommendation, would you replace now or wait for some other indication of failure? If working fine, leave it be. It is probably more reliable than a new drive. Just keep an eye on it. All disks eventually fail... it is just matter of waiting long enough. Joe L.
August 9, 201213 yr What is the make and model of drive? Also is the data on the drive active or static? Personally, I'd probably replace the drive purely do to age, pre-clear it a couple of times to certify it good, and keep it as an emergency spare for temporary use, or for extra off-site backup storage.
August 10, 201213 yr i might consider getting a new parity disk and demote that drive to a data disk.
August 10, 201213 yr i might consider getting a new parity disk and demote that drive to a data disk. Why? The parity disk is the least important disk failure wise. If you consider a 2 disk failure scenario, I'd much rather lose the parity + 1 data instead of 2 data disks. Now, if you are purely considering performance, I'll agree with you, as the speed of the parity drive limits all writes, so an upgrade to the parity drive should help write speeds overall to a certain extent.
