I've been listening to the discussions of data recovery technicians for many years. As such, I took a guess at the results before the page loaded.

And I was right. Seagate bad. Hitachi best. WD almost as reliable as Hitachi.

I can recall one or two bad WD models over recent years, the one at the top of my memory is the 500GByte WD5000AAKS. There was a flaw in the WD10EACS that made it park too frequently, but at least it had a parking ramp.

Hitachi has been a good vendor since the "deathstar" glass platter fiasco blew over. Now: Deskstar 7K's forever!

On the other hand, Seagate seems to ship flaw after flaw. Lately they tend to have spindle bearings that die if the drive gets bumped. If that doesn't happen, surely a head will go bad.

While I love these recurring blog posts, it would be even nicer if Backblaze could wrap a public API and/or pretty interface around their live monitoring.

I'd happily pay a small fee for access to an up-to-date snapshot when I'm in the market for harddrives.

The Seagate Barracuda 7200.14 3 TB drives are another story. We’ll cover how we handled their failure rates in a future blog post.

I'm really looking forward to this... could it be a similar problem to the one that caused the huge amount of 7200.11 failures a few years ago?

agreed. I think I had around 7 different barracuda 7200's.. not a single one remains operable, all failed, though they did survive >1yr, they just didn't have the longevity of WD's or Hitachi's which ran on the same infra (and in most cases, continue to run).

And they put out a ridiculous amount of heat too. I found a one that was too hot to touch in a 24 drive array which heated up the drives adjacent to the point that they too refused to work. So what looked like an extremely unlikely double drive failure ended up being only one.

It's funny how things can turn around so completely. Around the time of the Deathstar fiasco, you couldn't pay me to use a Hitachi. Seagate was the brand to buy. Now it's the complete opposite.

Looks like Seagate drives are at a very good price point for them, enough to compensate for the higher failure rates.

It looks like Blackblaze managed to build a system with good fault tolerance, such that they can control the $-price/failure-rate ratio as they need.

In summary: - HGST, good - WD, expensive (in bulk) - Seagate, we buy them despite failures
