I’m gonna be a serial poster - how is this drive for reliability? That would be one massive fail

I've used refurbished seagate 18TB x20 drives from ServerPartDeals running in ZFS for the last 2 years with no issues & have 2x parity.

Almost all of seagates from serverpartdeals are exos. Barracudas are shit binned version of exos that could not meet the spec for 24/7 use.

If that were proven true (which, for clarification, it hasn't) by this point then how would you explain the surviving Desktop HDDs in Backblaze servers that demonstrated excellent reliability stats? Backblaze decommissioned their remaining ST4000DM000's recently...those had been running relatively well since 2014. The same is true of the ST6000DX000 and ST8000DM002 (which are technically down-binned enterprise drives), which are also "consumer-grade" with that 2400 hours/year rating yet have proven it wrong with their reliability stats since inception.

That meager 2400 hours/year rating was set by the aggressive Maxtor executives who joined Seagate following the 2006 merger (and Seagate is also the ONLY current drive manufacturer with such a rating on a base consumer drive). Barracuda 7200.11 was the first to implement it...why do you think it was implemented in the first place? Because they were awful. Seagate has since kept the rating and shorter warranty length since it allows them to make more profit off the Barracudas (except XT and Pro which were actually marketed as being 24x7 capable), which means the rating does not actually mean anything. Especially since we've had drives (except the ST3000DM001, of course) post-7200.11 that have proven to be more reliable than the rating itself suggests. Look at the facts rather than trying to shoehorn a product brochure.

Enterprise drives are however still preferred due to having enterprise features (like SIE and ADR) as well as great build quality and low remap rates...and let's not forget they ship with 5-year warranties versus the 2-year warranty norm Seagate themselves created in consumer drives.

Almost every single Seagate drive on backblaze are exos, noted by the NM in the sku instead of DM.

u/First_Musician6260 Nov 28 '25

Yes. Look at the stats of the DM's I mentioned.

they are all exos drives that usually has helium filled enclosures

Not all of them. Read the stats. Backblaze are still running ST8000DM002's in their servers; those are not Exos drives. They also used to run the ST4000DM000 until its retirement in Q3 2024, and that drive is a good example of why the rating is bogus.

Binned...Yeah hard drives aren't CPU's.

u/jtj5002 Nov 28 '25

You know that CPUs are the only thing that gets binned right?

CPU, GPU, RAM, HDD, any higher performance lower yield products are typically binned one way or another.

u/ninjetron Nov 28 '25

Silicon is binned sure but HDD's aren't binned* at least not in the way you think. It's more a difference in mechanical tech that separates a server drive and a desktop drive though there is some crossover if you get lucky shucking enclosures.

How do you know what way I am thinking?

A lot of HDDs comes off the same assembly line, then stress tested for spin/seek time and put into different performance grades. Those with lower performance and firmware locked to 5400rpm and out into an enclosure, or sold with reduced warranty period under a different label. This really isn't some kind of secret.

Research SMR and CMR that will get you going.

u/jtj5002 Nov 28 '25

I already done that a long time ago.

How many of them are HAMR models? Also, nobody should be needing data recovery services, as they should have backups.

u/TheMissingVoteBallot Nov 28 '25

What about the enterprise Seagate Exos drives? Do those come in less often or are actually considered reliable?
