Spinrite taking 20+ hours on a 12TB drive on level 1

[dverdin]

Hey everyone, I got 3 x 12TB WD Reds (WD120EFBX - 7200RPM, 6GB/s, 512MB cache) for a new synology nas, and figured I'd do a quick check on spinrite to make sure they're not DOA.

They took about 21-23 hours each to finish at level 1, I didn't go to any deeper levels because the estimate was so long and I wanted to get started with my NAS.

But I just saw a post saying that level 2 should take about 4 hours to scan on an 8TB drive (https://forums.grc.com/threads/spinrite-on-synology-drives.1378/).

Why could my scans be taking so long? I'm using a fairly old computer, but I don't think disk access speed is an issue, since I can download at about 80MB/s over FTP, on a different drive that has half the reported read speed as the WD.

Could it be the drives? Or is it spinrite? I recall spinrite taking a fairly long time on the drive I'm using for FTP as well, when I ran it some years ago.

If y'all need the other drive & computer specs, I can get them for you later today or early tomorrow.

Thanks,
Dan.

Run a drive benchmark with SpinRite, and submit the relevant log here so someone might have some actual data to draw a conclusion from?

Thanks PHolder, that might take a couple days. I'll get on that once my synergy has integrated the third drive into the RAID.

I disagreed with Steve's claim a few posts further down that thread:

21 hours is maybe a little slow, but not terrible. My 16 TB drive took about 21 hours. Many factors can affect speed. I suspect your drives are fine.

Would also be good to know the specs of the machine you are running the test on
