With their volume they get a good price anyway so who knows if they pay 2% more or not.
We have to assume so, as they would get volume discounts on consumer drives, too.

Exactly - sure they get volume discounts.. but the consumer at volume is still likely 2% less than enterprise at volume.. that's cash in their pockets...
Of course as they drop out from the smaller consumer grade drives, that becomes less and less of an issue.

2% of 100k HDDs has got to be over $200k. The time that goes into replacing them, performance loss, etc can't be overlooked either, which is added costs on top of the drive costs.

In theory, from old BB studies, consumer and enterprise drives fail at roughly the same rates. Speeds are the bigger differences, and sometimes capacities. Often hard to directly compare as different drive types tend to be made for the different audiences.

I haven't seen those. In practice, it seems like a different story according to their charts.

Older blog, but BB stated that consumer drives outperformed enterprise drives on failure rates...

@scottalanmiller what's the general consensus here? Do we not buy Seagate because they fail more? Genuinely curious.
Generally avoid them, yes. Big usage shops like BB have had issues with them, and repair shops have advised that they see the failure rates on them in the wild being very high.
In 3.5" SAS we have plenty of 60-bay JBODs out there filled with Seagate NearLine drives. Our failure rates over the five year solution life across the board are virtually nil.
We had one drive fail in a Dell MD3060e but who the chicken knows what drive was installed in there in the first place.
We avoid Seagate SAS SSDs due to firmware problems that we've seen in the same settings.
We've been running with HGST now Western Digital drives and JBODs and have seen similar virtually nil fail rates.
As far as 2.5" 10K SAS goes, we have lots of Seagate and HGST out there with, again, very little in the way of fail rates.
Hard Drives have become quite reliable as a whole in the settings we deploy them in.
We've not deployed spinning rust in a workstation/desktop/laptop for years now. So, that negates the consumer side of things. We just don't.

Totally fine is its some kind of RAIN. Actually i'm looking at building a CEPH cluster, Dell&RedHat recommend using single-drive RAID0s

Our Storage Spaces Direct (S2D) hyper-converged clusters use IT Mode SAS HBAs for the SAS/SATA disk setup. NVMe are straight-through by default.

Many systems today can use JBOD, the system itself takes care of any reliability needs. Exchange added that back in 2013.

No it was about the 'term', nevermind lol.

Yes, even drives that fail "a lot" doesn't imply that you are likely to ever see one. If the best drives fail .000001% of the time, and the worst drives fail 300% as often, that's still only .000003% of the time.

If you add RAIN, it's not a JBOD
Then it is a RAIN. -

Everything uses JBOD at some level.
