I wouldn't say the above study is flawed but the conclusions oft drawn from it contradict the study's stated conclusions. It focused on a small range of model numbers (3) and is skewed by particular problems of one individual Green model. Storagereview.com shows a more balanced presentation whereby they found that Seagate had produced both the most reliable drive of all time and the least reliable drive of all time which should drive home the point highlighted by the above article that reliability varies more by model number than by brand name.
Note what the article actually states:
That doesn’t mean Backblaze is swearing off Seagate drives. In fact, the company has high hopes for Seagate’s new 4TB Desktop HDD.15 (ST4000DM000). Other Seagate drives are also big favorites with the Backblazers.
Backblaze said this particular model is pretty bad, but it cautions not to read too much into it. The company received these specific drives as warranty replacements, so they were probably refurbished with wear and tear on them by the time they met Backblaze’s HDD taskmasters.
Furthermore a careful read of the article had the company who did the testing take a direction opposite to what was taken above.
Your risk of a complete hard drive failure over the long-term might be higher with Seagate than Hitachi, Backblaze's numbers suggest at first glance but there’s no guarantee that will happen. In fact, Backblaze's earlier study showed that hard drives are actually pretty reliable overall over a four-year stretch, even in a server farm. And hey, a number of individual Seagate models actually had a longer average age than Hitachi products!
Buying based upon that article is relevant ONLY if buying the exact model in question and from the same "stepping". The problems in the study were limited to the Green model and therefore has no applicability to and gives zero indication with regard to the other lines which are of a different design .... and you would never stick a green drive in a gaming or enthusiast box anyway..... a decision the article author also made
For example, Backblaze said it will stop buying Seagate LP 2TB drives and Western Digital Green 3TB drives, because they just don’t work in the company’s environment.
Here is a recent analysis of HD failures of current models over last two sales periods as measured by the number of returns.
2012 was last english translation
http://www.behardware.com/articles/881-6/components-returns-rates-7.html
- Western 1.48% (against 1.63%)
- Samsung 1.65% (against 1.23%)
- Seagate 1.70% (against 1.89%)
- Hitachi 3.77% (against 3.95%)
Other than Hitachi, everyone is in the same ballpark overall .... but now let's look at the individual model failure rates for the OPs 2 TB drives .... 6 of the worse 7 are WD drives:
- 4.60% for the WD Caviar RE4 2 TB
- 3.91% for the WD Caviar Black 2 TB
- 3.32% for the WD Caviar Green 2 TB WD20EARS
- 2.28% for the Seagate Barracuda 7200.14 2 TB
- 1.94% for the WD AV-GP 2 TB
- 1.46% for the WD Caviar Green 2 TB WD20EARX
- 1.03% for the WD RE4-GP 2 TB
Moving to the latest sales periods we have to go to the original french site
http://www.hardware.fr/articles/920-6/disques-durs.html
- Seagate 0,86% (0,95%) ~ average 0.905 % or 9.05 per 1,000
- Toshiba 1,02% (1,54%) ~ average 1.28 % or 12.8 per 1,000
- Hitachi 1,08% (1,16%) ~ average 1.12 % or 11.2 per 1,000
- Western 1,13% (1,19%) ~ average 1.16 % or 11.6 per 1,000
Again, for the OP's desired 2TB, the individual model return rates are listed below by model number from worse to best. WD has 3 of the worse 4 and 5 of the worse 7, but like Seagate that also have a model with 0.00 % returns tho I'd venture to guess this is driven as much by actual reliability as limited number of actual sales.
- 2,64% WD Green WD20EARX
- 2,15% Toshiba DT01ACA200
- 1,46% WD Green WD20EZRX
- 1,05% WD Red WD20EFRX
- 0,97% Seagate Barracuda 7200.14 ST2000DM001
- 0,95% WD AV-GP WD2EURS
- 0,85% WD RE WD2000FYYZ
- 0,72% Seagate Enterprise Value ST2000NC001
- 0,49% Seagate Surveillance ST2000VX000
- 0,00% WD Black WD2002FAEX
- 0,00% Seagate NAS HDD ST2000VN000
We have 10 boxes here (5 desktops / 5 laptops) almost all have multiple HDs and I'd say 2/3 Seagate and 1/3 WD ..... In the last 3 years, we have purchased nothing but SSHDs. I have not had a "HD fail in a machine" in over 11 years.... as machines get retired (typically 4-5 years), we use the old drives for backups or for moving data between machines and the only one that did fail was an old WD black that was over 7 years old.
While everyone worries about CPU and GPU heat, peeps rarely think about HD heat. IBM's study showed that an increase of 10C will halve HD life but repeated and wide thermal cycling is probably their biggest enemy. After transporting your PC to college and leaving it in your cold car for a few hours, don't bring it into the dorm and fire it up before it warms to room temp.. Also vibration is something HD's don't like .... Quality cases with rubber feet and vibration isolators on the HD trays help reduce wear and tear.

Anytime you pick a PC component by brand name, you are running a fools errand.
"Corsair makes great PSU's"....yes, they do make some excellent PSUs (Axi / HXi Series) .... they also make some really crappy PSUs (CX / CSM).
"Asus makes great MoBos" .... yes they have some great model lines and some that are "not so" much", quality is declining judging by % of negative review % in past years.
"Seagate has bad quality and high failure rates" .... yes, their 7200.11 had a firmware issue and the Green line has had it's issues, but their enthusiasts drives and SSDs perform better and have comparable reliability rates as anyone else.
"WD has great drives with great performance ".... yes the WD Black is a great drive, though it's performance isn't keeping up with newer models from the competition and it's high price (no doubt significantly associated with warranty costs for the excellent 5 year warranty). There are other good model lines, however, the reliability and performance of some other models has proved to be quite dismal.
Best to forget brand names as the single arbiter of performance and reliability and pick your components by the specific model number using reputable indicators of performance / reliability. Note also, that manufacturers also sometimes make design changes after all the reviews are done (monitor manufacturers especially) so be on the look out for such shenanigans.
