Helium;
HUH728080ALE600 8TB 4 yrs old, 0.8%, that’s less than the new-drive 2018 report!
ST12000NM007 12TB 28mths old, 2.1% hmm.
Sample size from both kinda small. Hopemy 16TB Exos16 drives last forever.

I have been trying to understand the columns in the charts:
Drive Count = number of drives you guys have
Average Age Months = Average Age in Months of the drives
Drive Days = Total number of days all of these drives have been going (maybe??)

If I take the very first line of the first chart:
Drive Count = 3531, Ave Age Months = 59.3, Drive Days = 312911

Now here is where my logic fails:
Drive Count * Ave Age Months * Day in a Month (Should) = Drive Days
3531 * 59.3 * 30 (ish) = 6,281,649

That is about 20 times greater than the reported Drive Days of 312,911

So what am I missing here? are the drive days the total time the drives are spinning? or something like that?
(In which case the drives are only spinning for a little over 1 hour each day? that does not sound right.)
So I am vey confused…..

Can somebody please explain what I may be missing here?

Thanks

In reply to McTavish. There is huge difference between RAID-protected data storage developed to tolerate single-drive failures, and individual usage, where, even if you have backups, you can spend a day or more replacing failed drive

Are HDDs in general not failing in droves anymore since I got Windows 10? or is it my imagination?

Back in 2018 you wrote about helium filled drives and that you would continue to track them. Is there any way to identify the helium filled drives in your tables? You know, instead of me actually having to look up each model number like a non-lazy person..
