Backblaze, an unlimited online backup company that keeps 25,000 hard drives spinning at all time, has published its results on hard drive lifespan — and it makes for very interesting reading indeed.

How long does a hard drive last?

Backblaze has kept up to 25,000 hard drives constantly online for the last four years. Every time a drive fails, they note it down, then slot in a replacement. After four years, Backblaze now has some amazing data and graphs that detail the failure rate of hard drives over the first four years of their life.
(...)
If you buy a hard drive today, there’s a 90% chance that it will survive for three years. If your drive makes it to the three-year point, you would be wise to back up your data, as there’s a 12% chance per year that your drive will die. It’s worth noting that these figures are for internal hard drives: External hard drives, for a large number of factors, may not last as long (though if you only plug it in every few days to back your data up, it might last longer). It’s also worth mentioning that Backblaze’s drives are spinning constantly — these failure rates are for drives that are turned on 24/7. Your home computer probably isn’t powered up 24/7, and thus the drives may last longer.

i never had a hd fail critically. I once had one that made a mechanical clicking noise lol, but even then it went on for over a year without actually failing ^^. And my pc is on pretty much 24/7

Never had one fail badly either, the current oldest one is a 2 Tb drive that's currently in my older PC which my sister is using. Smile
(All I changed was the GPU from a 4890 to a 7970 and that PC is about eight years old now and functioning as it should, granted she uses her own HDD for primary and this one for storage but it's functional although I wouldn't be surprised if it does fail within a few years.)

My HD is almost 8 years old and still functioning well. I've worked with these kind of situations while I was still employed in IT business so I'm aware of the risks involved. It just seems to happen to other people, not me. Mr. Green

For the record, my computer is always on.

Old HDDs are actually more reliable because they used less platters and more importantly the URE rate has been constant while the capacity of the drives have been increasing, which means more unrecoverable errors per full drive read


Hear what you're saying. My first computer was scavenged from scrabs I got from my summer job. Old IBM cash systems, the times you were lucky to find 2 gig drives if you searched long enough. Those were the days. Laughing

I still have that computer, used it for years in the side of my newer systems. The hardware dates back to late 90's and guess what: the fucker still runs! Not a sign of slowing down.

Indeed. Old gear was generally more long-lasting.

If it comes to total disk failures, I've had many friends asking for support with total drive filures. I, somehow, didn't have a total one, although, one of my 160JJ's got bad so much, it peaked 4,5 mB/s read and it took like 24 hours to back it up =)

I have had 2 hard drives fails this year and 2 and past two years.
One was WD Green, was using it on my media player only, it only contained 1080p movies so it was on maybe 20 hours a month total.

Let's see, rest were seagate Barracuda. 1TB and 250gb. 250GB were at least 4-6 years old. So, I think they served me very well. 1TB was about 3 years old.

That's not counting SSD that died and 10K WD Velocity Raptor. Both died within 2012 as well ><

Honestly, I have no luck with hard drives, in those cases only was able to copy files from one, rest were just suddenly dead. They were used just for storage only so, I didn't really access them often at all.
