If you read the article, you would notice that "seagate customers don't keep backups" is not the actual conclusion of the study (its just what it proves when analyzed by someone more competent, like me and probably a lot of people making comments on the article)...
Anyways, they took data from a data recovery company in russia, called it "failure rate data", and slapped it with a LOT of disclaimers about it being "a specific market" and "limited dataset"...
Which is downright stupid, the dataset is large enough to be highly reliable... what they fail is on the ANALYSIS part... The data is amount of HDD for which the owners pay (A LOT) for recovery of of data, not failure rate by company data. (it is, however, failure rate by MODEL data... which does show that most Seagate failures came from one drive design)
Seagate customers are simply least likely of any company to keep backups, or most likely to afford paying for data recovery, or both. Someone with extremely important data, a lot of money, and very little knowledge or intellect thinks "wow, I got this important data, I need to store it somewhere safe! I know, I will ask around and buy a HDD from a company I am told is the most reliable! that way I know for sure my data is safe! wow, a 5 year warranty? I must not even need backups!" so they do... Some blame can be laid at seagate's own advertising, tauting its "reliability" (to justify higher costs).
Interestingly, hitachi (the maker of the CHEAPEST drives on the market), has the least amount of data recovery requests... is this due to being the most reliable? no, its just that if people buy the cheapest drive on the market, they either keep backups, or don't care enough about the data it contains to pay for recovery.
PS. this is why it is so important, in science, to publish your data and procedure along with your conclusion... someone else can reanalyze the data and come up with a better, more sensible conclusion based on the same data.
