Hard Drive Reliability Update Sep 2014

Quote:
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.

I did a blog post back in January, called What Hard Drive Should I Buy? It covered the reliability of each of the drive models that we use. This month Im updating those numbers and sharing some surprising new findings.

Reliability of Hard Drive Brands

Losing a disk drive at Backblaze is not a big deal. Every file we back up is replicated across multiple drives in the data center. When a drive fails, it is promptly replaced, and its data is restored. Even so, we still try to avoid failing drives, because replacing them costs money.

We carefully track which drives are doing well and which are not, to help us when selecting new drives to buy.

The good news is that the chart today looks a lot like the one from January, and that most of the drives are continuing to perform well. Its nice when things are stable.

The surprising (and bad) news is that Seagate 3.0TB drives are failing a lot more, with their failure rate jumping from 9% to 15%. The Western Digital 3TB drives have also failed more, with their rate going up from 4% to 7%.

In the chart below, the grey bars are the failure rates up through the end of 2013, and the colored bars are the failure rates including all of the data up through the end of June, 2014.

That is a good read Shawn I have said for along time now to others that I will not have large drives because large drives crashing means loss of a lot of data. I prefer to have multiple 500GB drives - not that I store a great deal and often wonder what on earth requires a 1TB drive for storage? plus multiple small ones works out cheaper.

I am not deriding those who use large drives just think maybe sometimes people think bigger is better

The other interesting point was Seagate not doing so well in the larger drives as I am a real fan of that brand and even more interesting was how the Hitachi came out that good.

Mind you as you know al too well quality depends on where and who makes the equipment and we know where it all comes from these days eh?

A small drive can fail just as easily as a large one. All spreading your data over more drives does is reduce the amount of data lost if a single unbacked up drive fails. However, as long as one maintains proper backups, one will not lose ANY data, no matter what size the drives. Larger drives mean fewer drives, which reduces power consumption, weight, heat generated, less room occupied, etc. which frequently can offset the increased cost per GB of the larger drives, not to mention be more convenient. As long as one's data is properly backed up, it doesn't matter how large a failed drive is; no data will be lost.

Considering that data not kept in at least three places (one source drive and two duplicate drives, for example) is not secure, the more drives one has, the more backups one will need to maintain.

Just because you don't have high data storage needs doesn't mean others do not. I have all my CDs ripped to my computer, each one in both wave and mp3 formats, and all the liners notes scanned. Those rips occupy around 1/4 of a 2TB HDD (plus four backup HDDs). All five HDDs take up vastly less room than the 500+ CDs would have in their original cases (I plan on doing the same with my videos, which will be an even greater space and weight savings although they will have to have their own HDDs). I can easily put multiple CDs and partial CDs on an unlimited play list I can save for listening to later on a single file that occupies only a few KBs.

The only books I buy anymore are ebooks, which take only a tiny amount of disk space each. I'm slowly scanning my dead tree book library of several thousand books to PDFs (I'm over halfway finished). The same five duplicate HDDs that house my music collection and their backups have more than enough room for my entire library (I am a very voracious reader, especially now that I'm retired, and I reread my books, sometimes more than once). Even as large as the files for my scanned books are, they take up little more room on a HDD than my music collection does. That beats the heck out of 40 banker boxes of heavy dead tree books.

Many people record their own TV shows to watch later or even save. Bluray rips can take as much as 50GB of space each.

Well I am sorry I trod on your toes Jeannie you are right with personal choice of course but I am logic driven

Quite frankly and hoping I don't provoke any more offence but storing that much data is a mystery to me simply because if you have read or watched that much surely you would not trawl back through it to see it again and storing that much music well how is there enough hours in a day to hear it again??

I have long believed that the larger drives available at any given time are pushing the envelope of what technology can provide at a reasonable price. A problem that has plagued drive manufacturers for a long time is the constant pressure for larger and faster drives without raising the price. Better manufacturing techniques and a bigger market can only go so far in making that possible. Reliability often suffers.

So you are saying I'm illogical?

Other than your fallacy of spreading data out over multiple HDDs to merely minimize loss (instead of utilizing proper backup procedures to eliminate data loss), my biggest issue was you imposing your needs and values on others, which you have just done again. You may not want to listen to much music, watch many movies, or do much reading. I, and many others, can listen to music all day, and listening to the same old same old would get boring, hence the desire and need for a large variety. I can easily go through an eight hour play list in one day. Same for books and movies. I have one book I reread once a year (Wind in the Willows). There are a several others that I read every two or three years. Other books I may not read again for many years but, unless the book was a dud, I will eventually reread it, often more than once. Same for movies, I eventually rewatch most of them, some more than others. I'm not the only one who does this.

Backups, Backups, Backups ...

If you can't use more than a few hundred GB, you aren't creating enough backups.

Ignoring my Music (120 GB) and Video (1.5 TB) partitions, my standard monthly backups are ~120 GB in size (documents, pictures and operating systems).

My PC has ~5.5 TB of internal storage.
I have ~9 TB of backup capacity on external HDDs (used for music, video, documents, pictures, VMs and operating systems).

When I work on videos I normally end up with at least 3 complete versions (original, partially modified and final).

I have ~11500 mp3 files.
I let Winamp play them in Shuffle mode, whilst I do other stuff on my PC.

Call me Simple Spencer, but 500 GB is still pretty much a bottomless pit for me.

I don't really like HDDs with bigger capacities. Bigger capacity means slower performance. I wish to buy an SSD but unfortunately I don't have money for it

Ah well I do listen to a lot of music and watch films but not through a computer I don't see the need. But I have obviously upset you so I shall duck out as you seem to think I am some sort of crank or an idiot who just wants to stir things up when I am doing nothing of the sort. I just said big drives big crash and therefore big data loss if that is not logical well perhaps I should give this all away. That tells me straight away that you have your opinion and woe betide the person who even goes close to disagreeing with you.
As for you saying I was imposing my will or thought on anyone is really quite offensive and preposterous. It implies that the others are like lemmings with no minds of their own and would follow my every move or suggestion.
Moreover it proves to me that you do not know me at all and I am at a loss as to why you should even suggest that for that reason alone .
