A warning about 8TB+ drives - Be cautious - Be aware - Higher rate of failure (degraded surfaces)

post #1 of 44
Thread Starter 
Hey everyone,

Just wanted to do a PSA regarding 8TB+ sized drives. Due to the increased capacity and complexity, these drives have a much higher rate of failure. Especially with bad blocks. So far I have had 7 separate RAIDs come in with Seagate, Hitachi and WD 8TB and 10TB drives. This totals approx 50-60 drives. Each one was 5+ disks and each had at least 2 or more failing drives with multiple bad sectors. No mechanical failures but rather degraded. Most of these drives are less than a year old.

I repeat, 8TB drives have a higher chance of failing and can become degraded rather quickly.


Not saying they are bad but so far there seems to be issues. Please proceed with caution.

Maintain a backup at all times.

Thank you,

Xeb

This is why I stuck with 3 TB when I just recently rebuilt my entire UnRaid array.  I figured higher density hard drives would be less reliable, but not to the degree you just mentioned...

What brands were the drives?

All brands. WD, Hitachi/WD, Seagate, etc.

The ones I am seeing are the NAS ore NASware drives. However, I have seen archive drives as well. Just anything 8TB and up.

what about the hitachi he10, he8 helium drives HUH721010ALE604, HUH721008ALE604? they say they use less power = less heat.. etc...

what do you think of the hitachi he10, he08 drives? hitachi's the leader using helium technology


https://www.hgst.com/products/hard-drives/ultrastar-he10


can you log the part number of these drives you're getting? part numbers because only manufacturer brand names doesn't mean much.

My post applies to ALL of them. Every RAID that had helium drives in them had at least 2-3 drives with bad sectors and beginning to fail. Each drive was less than a year old.
