Question: This may be a bad idea to consider but has anyone used Amazon Renewed hard drives? I’m thinking it may be worth a risk if I purchase 6 renewed drives (same model & capacity) and run it at RAID 6 as a NAS. If any drive fails within the warranty period, I should be able to get another renewed drive.

Feedback is appreciated.

Answer:

Did you implement JBOD with a backup but no RAID?

Yes.

Each of my systems run a nightly backup to the QNAP NAS volume. 8+8+8 JBOD.
The QNAP NAS runs its own weekly backup to a QNAP TR-004 enclosure, 4+4+4+4, also JBOD.

No RAID needed.

AS stated, the QNAP was originally 3+3+3+3, RAID 5. Swapping to 4+4+4+4, with a RAID 5 rebuild in between each new drive…that rebuild took 6-7 hours.
Similar as to replacing a dead drive in that.

Right then, I decided that the RAID was not really doing anything of any importance. Replacing a dead physical drive is just as easily handled by the actual backup. Along with all the other things a true backup protects against.
