Scott,
I see you've mentioned the link between hard drive failure rates and hard drives. What's your take on the Google study on hard drive failure rates. I realise this is old news, but I don't think I've seen it cited here.

That google study has in fact been cited here on the forum. My take is that it is very interesting research, something we can all learn from. I was a bit surprised that up to a certain point, temperature did not have as much of an effect as I would have thought. Scott.

For forum reference, I think I would like to link the Google study mentioned above to this report on a Russian study on hard drive failure.

Study: A Look At Hard Drive Reliability In Russia

Tom's Hardware
August 13, 2010

Storelab, a Russian player in data recovery, recently released a long-term study comparing hard drives from a number of different vendors. The controversial report offers interesting data and provides a snapshot of HDD reliability and defect reasons. ....

There is a thread on here regarding a Google paper on reliability and the original Backblaze report. I apologize as I cannot find it to add this to it. Feel free to merge it. Thought this might be of interest. [hattip: MarkM @ hardwareguys]

Hard Drive Reliability Update – Sep 2014

https://www.backblaze.com/blog/hard-dri ... mber-2014/

At Backblaze we now have 34,881 drives and store over 100 petabytes of data. We continually track how our disk drives are doing, which ones are reliable, and which ones need to be replaced....[continue reading at above link]

Backblaze has posted an new update on their data:

What is the Best Hard Drive?
https://www.backblaze.com/blog/best-hard-drive/

It was one year ago that I first blogged about the failure rates of specific models of hard drives, so now is a good time for an update.

At Backblaze, as of December 31, 2014, we had 41,213 disk drives spinning in our data center, storing all of the data for our unlimited backup service.... [continue reading at above link] [hattips to ars technica and LatiosXT @ MaximumPC]

I continue to wish more server farms would publish their drive failure data (and get some marketing attention for themselves).

I agree, and thanks for posting another update, this is very interesting information. I am eager to see their upcoming post about the high failure rates on the 3TB Seagate drives. Scott.

Here is another HDD failure report (return rates) link pointed out by satrow @ Windows Secrets and its associated page links [#6] to the whole article. It is in French (Google Translate link below). Loses a bit in translation I'm afraid.

original if someone wants to translate it for themselves or read the original French:

For completeness I have included a couple more links I came across today while researching HDD failure.

Everything You Know About Disks Is Wrong
http://storagemojo.com/2007/02/20/every ... -is-wrong/ - includes older study links and comments upon them

http://www.tomshardware.com/reviews/ssd ... 923-9.html - SSD compared to HDD failures which it discusses though direct comparisons between the two were not done. note: page 9 link...use drop down to start at page one.

Very interesting, however I would caution that those reports date from 2007 and 2011. HDDs and especially SSDs have evolved considerably since then. Scott.
