Hitachi does really well. There is an initial die-off of Western Digital drives, and then they are nice and stable. The Seagate drives start strong, but die off at a consistently higher rate, with a burst of deaths near the 20-month mark.

It was a good read. I wouldn't imagine Hitachi to perform so well. :)

Very good reading indeed.

 

I bought about 40 (cheap) NAS 3 years ago with Seagate drives.

They all died due to disk failures within 24 months.

I realised afterwards I was unlucky as that one specific Seagate was bad luck (bad firwmare, "busy" mode bug...).

Still, next batch I buy wont be Seagate drives....

 

Where I work, we also that many WD drives : these are pretty good.

 

As a whole it would be interesting to know what fails : the electronic part or the disc/media part.

Another interesting part would be : does failure rates change with SSD drives.

 

And last but not least, the conspiracy guy I am could wonder if since profesionals all make their drive redundant (x2,2,4,5,10, etc) : are not drives programmed to die after X (short) years.

Or the other me, the "old" guy could also wonder : were not drives lasting longer before? as in "it was better before" :)

From my experience:
2 IBM/Hitachi IDE HDD - run straight for now almost 13 years - no problems
3 Samsung IDE HDD - run straight for now almost 11 years - no problems
3 Seagate IDE HDD - home usage of about 3-5h a day - 1 died after 3 -, 1 started misbehaving after 2 years
5 WD IDE HDD - office use 8h a day - 4 died in short succession after just 2 years, so i replaced all 5 with Samsung ones.
5 Samsung IDE HDD - office use 8h a day - 8 years - no problems

For my money IBM/Hitachi and Samsung built the best HDDs. Strangely they were purchased by the two companies which build the worst drives, not the other way around.
It seems to pay better to build junk than quality. :frusty:

You may find it satisfying to peruse this website, e.g.;

For my money Samsung drives are the best, i ever had.
They are the most silent ones and run very cool compared to all others. Reliabilty is also top notch as already stated.

In my experience drives die of the following:
- electronics die of overheating
- motors burn out during start-up
- heads crash because of warping of the platters due to heat or vibrations

So the possible best treatment for a HDD is to run it continuously, well ventilated and well mounted.

btw. Mounting HDD standing up instead of horizontally can save you the use of an extra fan.
I tested this idea first some years ago, after seeing it in an Alienware tower. The WD HDD i used for the test, would run up to 51°C horizontally, but 'only' 42°C vertically.

I'm agree about Samsung HDD was the best option, they started the 3 year warranty in HDD's. But Samsung sold the HDD facility in 2012 to Seagate.  AFAIK warranty is only 1 year now from all brands (Toshiba, WD & Seagate). This is the last info I found abut HDD manufacturers http://en.wikipedia....urers_and_sales

If they would at least buy the other companies to get their hands on the superior technology. But they just buy the other companies to weed out competition and keep producing their inferior crap.

I just hope my old HDDs will keep working till SSD become cheap enough, to buy from quality manufacturer again.
