22TB drives have not been in production 5 years. The earliest review I could find was from August 18, 2022 from a Western digital gold.

https://www.storagereview.com/rev...hdd-review

So less than 3 years use maximum.

Prices of refurbs tend to drop towards the end of the year as datacenters liquidate "aging" drives. That's what we saw last year, there was just a flood of cheap really good quality refurbs.

These drives have like a 2 million hours MTBF rating... So even supposing 5 years in a data center:

5 years = 24 x 365 x 5 = 43,800 hours

This is only a fraction of the 2 million so these drives still have a lot to give!

The recent large (especially 24TB+) Seagate external drives appear to be HAMR. These 22TB MDD drives might not be, though I can't say that for sure. HAMR drives usually have a laser warning on them, but I don't know if MDD would even bother. Also, as far as I know, any CMR Seagate over 24TB is definitely HAMR.

If you're seeing warnings in Event Viewer, I'd definitely do some thorough diagnostics. Also, make sure you're looking at the right drive. I believe Windows labels the first drive as Disk 0, leading to some confusion.
Thanks for the detailed reply. Disk2 is the 2nd disk in my RAID1 array, and I'm wondering if the warnings are just the disk taking too long to spin up when being accessed, because the string of warnings are all within a few seconds, with hours or days between the next set of warnings. Disk checks have not found major issues.

I suppose it's possible, though that would strike me as strange. With the warnings all being within a few seconds, I'd be inclined to think the drive was struggling, trying to read a bad sector. Have you run a full surface scan and checked the SMART attributes?

Sure I don't see why not but I prefer WD drives.

The Exos is likely a safer bet.

That's not what MTBF rating means
That's a good thing to know. However, stating that without explanation is not helpful. AND, in such explanation, can one surmise any correlation to longevity? If not, what is the purpose of "reporting"/"publishing" MTBF by manufacturers? BTW, I know what the acronym stands for. By statistics, it's just that-statistics. So, it still should be reliable... as I understand statistics. Please elaborate answers to my questions and expand on your response, "That's not what MTBF rating means."

Anybody thinking drives go anywhere near 500,000 hours assuming on/off cyles in a desktop environment is smoking something... 2m mtbf is an aging process and subjective... based on the disk parts only, not the elecrronic board interface

What's the difference between enterprise, NAS and surveillance hard drive? Just the end user application or something beyond that? Which one would be superior in terms of functionality and longevity?

My understanding is that while physical construction may be different in some cases, in others, these different classes of drives are identical or very similar with just some small adjustments like more built-in vibration dampening materials. But the main difference lies in the algorithms in the firmware that are tuned for particular types of workloads. I'm sure somebody here knows lots more details.

If you look at the model numbers of these drives, the whole first part of the string is identical, and they are just differentiated by the suffices, i.e., "E" for "Enterprise", "NAS" for NAS, and "DVR" for the surveillance style. So a simplistic interpretation might be that the drives are mechanically very similar, but their firmwares are tailored to the specific types of workloads they expect to see.

Again, happy to hear more from an expert out there!

They also have 3TB SAS on their website with 3 year warranty for $12 shipped. Mine turned out to be a Toshiba model, $4 a Terabyte.
