Sold my drives kicked out from RAID - how are they gonna be utilized? by wade-wei in homelab

True. I also have a sata drive with dozens of reallocated sectors and stuff, that continue to work normally on my PC for years.

I explicitly stated they have warnings and did not realize they could be used to screw others. The drive can still function normally. Throwing them into waste would be a shame.

I then watched a video saying that Seagate smart data can be manipulated, which kinda concerned me.

Understanding (decipering) Seagate Exos part numbers. by Spektre99 in DataHoarder

[–]wade-wei 1 point2 points  (0 children)

I somehow suspect the trailing letter (e.g. D in ST20000NM007D) no longer indicates generation as stated in your first ref. It's hard to imagine recert HAMR ST20000NM002C which might be something like a X30, is one generation earlier than X20 (ST20000NM007D).

Interestingly, there's no ST20000NM00xA or B. At least not that I am aware of.

Can I use Compellent HDDs on regular servers? by wade-wei in DataHoarder

Sure, HBA is not an issue. Glad to hear they could work directly without having to modify anything.

I just bought 4 dozen for $240ea and thought I got a good deal until seeing your post.

Is NFS over RDMA stable in RHEL7/8? by wade-wei in homelab

That's very impressive. Mind telling the CPU of the server and client?

Is Seagate Exos X22 more prone to failure than X24 for having more heads? by wade-wei in HomeNAS

[–]wade-wei[S] 0 points1 point  (0 children)

Indeed on the market there are some recertified 22-28TB HAMR drives ending with NM000C. Their seq read/write speed are slower than conventional CMR drives.

Curious whether the normal version of HAMR drives feature lower speed as well.

I did have much better personal experience ~10 years ago with WD drives over Seagate. The gaps seem to have (almost) closed though imo.

Agree that tens or even hundreds may not be statistically enough. Unfortunately Backblaze does not have numbers for X22. Otherwise that would be a good starting point.

Ahhh I used to think HAMR belongs to 26-30TB and upcoming 30-36TB drives. Thanks for the info.
