Howdy. So I’m in the process of building a new pool for my NAS. I have eight 18tb drives that I’ve burnin with Spearfoot’s disk-burnin-and-testing script from GitHub. Everything has been going smooth so far at 65 hours in. I do have one possible issue however, one of the drives is testing at a slower rate then the others.
| 90.82% done, 65:24:36 elapsed. (0/0/0 errors) | 95.90% done, 65:24:51 elapsed. (0/0/0 errors) | 88.11% done, 65:24:43 elapsed. (0/0/0 errors) | 53.61% done, 65:24:35 elapsed. (0/0/0 errors) |
|---|---|---|---|
| 88.58% done, 65:24:38 elapsed. (0/0/0 errors) | 89.32% done, 65:24:49 elapsed. (0/0/0 errors) | 88.89% done, 65:24:46 elapsed. (0/0/0 errors) | 94.82% done, 65:24:37 elapsed. (0/0/0 errors) |
So these look good so far, the majority of the drives which are chugging along within + or - 5% of one another. While that top right drive that has fallen behind and is now -40% behind its peers and it continues to slowly fall away from the pack.
So my question is does this drive have an issue where its running at a slower speed to its peers or is this nothing to worry about? Once the burnin has finished I was thinking I would speed test each drive and see if anything shows up.
Any ideas or comments?
Thanks all.
Yep, I’ve seen drives that are 100% green on SMART and self tests but operate slow as dirt. Although, of course, you’re going to want to make sure that it wasn’t the cable or something.
