Hard disk reliability examined once more: HGST rules, Seagate is alarming

For a second year, the standout reliability leader was HGST. Now a wholly owned subsidiary of Western Digital, HGST inherited the technology and designs from Hitachi (which itself bought IBM's hard disk division). Across a range of models from 2 to 4 terabytes, the HGST models showed low failure rates; at worse, 2.3 percent failing a year. This includes some of the oldest disks among Backblaze's collection; 2TB Desktop 7K2000 models are on average 3.9 years old, but still have a failure rate of just 1.1 percent.

At the opposite end of the spectrum are Seagate disks. Last year, the two 1.5TB Seagate models used by Backblaze had failure rates of 25.4 percent (for the Barracuda 7200.11) and 9.9 percent (for the Barracuda LP). Those units fared a little better this time around, with failure rates of 23.8 and 9.6 percent, even though they were the oldest disks in the test (average ages of 4.7 and 4.9 years, respectively). However, their poor performance was eclipsed by the 3TB Barracuda 7200.14 units, which had a whopping 43.1 percent failure rate, in spite of an average age of just 2.2 years.

...

As before, this doesn't mean that anyone with a Seagate disk is at risk of an imminent hard disk failure (though you should always have backups!). Backblaze operates disks outside of the manufacturer's specified parameters.

God damn Seagate.

The study: https://www.backblaze.com/blog/best-hard-drive/

They have a lot of data. Wish Amazon, Google and Facebook would publish their data.


Note: Some people are asking if this applies to SSDs: No, this is stricly magnetic hard disks (HDD).

I think my 2tb drive in my computer is a Seagate I got back in 2010 and its fine. Good to know not to buy any recent ones though.

I bought a Seagate as the first drive in my NAS last year, right before the 2014 numbers from this test came out, and the first thing I did when I saw them was buy a drive from another manufacturer to mirror it. It's still working but man, those 3TB numbers are insane.

Mine is the 4TB, admittedly, which looks fairly reliable.

New year, same as the old year.

I have a couple of 500GB Seagate SSDs that my father had that he didn't need.
I think I'm going to put them into a desktop build later this year in a RAID1. Since, I figure they're not likely to both die at once >.>

Well this doesn't discourage me from getting more 4TB seagates I guess.
Kinda funny to see that considering my 1TB Seagate from 2008 is still kicking and so is my 300GB from 2006 for that matter.
 
It should be noted the high failure rate is specific to 3TB drives. Backblaze actually recommends the Seagate 4TB drive as an affordable option to the Deskstars.
 
However, their poor performance was eclipsed by the 3TB Barracuda 7200.14 units, which had a whopping 43.1 percent failure rate, in spite of an average age of just 2.2 years.

I think that's the one I bought a few months ago :(

I've owned one Seagate in my life.

One.

In all the years - and there are *many* - that I've been dorking around with the guts of computers, I've never had a HDD fail on me THAT FAST. It was breathtaking, we're talking months here. I've sworn allegiance to Western Digital. HGST-proper is nice, but the selection always seems to be pretty limited and branded WD price/space ratios are really hard to beat. Yay volume! :)

I would like to see a test of the enterprise hard drives. The Seagate enterprise drives are bullet proof.

I have an external 1.5GB Seagate that I use as a backup drive. God Damnit!!!!!!!

Oh great, my Xbox One external HDD is a Seagate 3TB. I almost always buy Western Digital, but this one was on sale on Black friday.

One thing to remember is they're stressing these drives. Your drives may not see the same level of I/O as their stress test, so I wouldn't rush out to replace it. HDD also go through many different lots and without a specific lot it's not clear just which drives were failing.

While hard to argue about lesser reliability of Seagate drives this days, Blackblaze's case study is very narrow. Almost no home user will abuse their drives to extend of online backup company running raid arrays. And AFAIR they're replacing faulty drives with exact same drive so one bad model can skew results.

I feel pleased that the Seagate I took a chance on at Boxing Day was a 4TB. Looks like they're nice and reliable for some reason.
 
Yeah I just had a catastrophic failure when 1 seagate disk died and another one died during reconstruction of the volume (only 1 disk redundancy) - still pretty pissed at losing all my personal data :(

(3tb drives)
 
HGST failure rate is damn low! I'm gonna need a few drives like that for storing my old-PC stuff one day. My old man usually goes with SSDs these days, but we have some bigguns in her inventory as well.

I remember when IBM's were awful and WDC was the best.

pshhh that was one model that was shit , before that IBM ran all things storage , they got out because it became a commodity item and why spend money for storage you are going to be giving away. it was like the GXP75 or something all the previous models were the standard of the industry and they sold the division shortly after, 2 other makers got gobbled up around that time too, Quantum and someone else.
 
I'm not very savvy when it comes to pc's so please be gentle..

I think I have a seagate hybrid ssd hdd in my pc. When I play games (on mid to high settings) my computer would reboot during load times. Prior to rebooting, I would hear some "straining" sounds coming from the pc. Could this be a hdd issue?

Thanks in advance

Fuck Seagate in the ass. Had one of their 3TB externals... died after a year taking down tons of old important data. Now I have to spend hundreds to have it all recovered. Never buying a Seagate product ever again.

I'm not surprised those 3TB Seagate drives are horrible. I had two of them that died after less than 18 months.

Seagate is even worse than the 'HITACHI DEATHSTARS' all my physical drives are WD these days
