The thing about the 7 year number is that it's just for the heads. Assuming these still need helium, I suspect they won't actually warranty the drives that long.
7 doesn't really mean anything unless they dare to give warranty for that amount of years. 20+ drives I have have exceeded 7 years and are still working anyway, proofing further that 7 number is empty theory.
How can you have MTBF of 2.5 Million hours (285 years) if you expect the head to last only 7 years?(4-5 years for PMR). Can someone who understands this please elaborate. This does not make any sense to me.
MBTF is statistical term, it expects 1 failure every 2.5 million hours. they can convert this to AFR (annualized failure rate) that makes more sense to direct consumers with single drive: 0.35% AFR. essentially, if you only own 1 drive, you have 0.35% chance it dies in 1 year. If you own 10.000, then 35 will likely die.
thus 10k drives * 365 * 24 hrs, divided by 35 drives = Voila! 2.5 million hours between failures (per drive).
I'll be more impressed when they're actually purchasable, considering they were announced as shipping 3 months ago but have yet to show up at any of the usual large wholesalers (the kind who sell to enterprises)

Might be the higher-density required which is why older technologies last longer.artifex - Wednesday, April 24, 2024 - link

A Seagate drive that lasts 7 years? Sounds like the exception rather than the rule.Reflex - Wednesday, April 24, 2024 - link
Buy the Exos line, they are great and well priced too. I use them in my NAS setups and they go forever.stoatwblr - Thursday, May 2, 2024 - link
