25,000-Drive Study Gives Insight On How Long Hard Drives Actually Last

MrSeb writes with this excerpt, linking to several pretty graphs: "For more than 30 years, the realm of computing has been intrinsically linked to the humble hard drive. It has been a complex and sometimes torturous relationship, but there's no denying the huge role that hard drives have played in the growth and popularization of PCs, and more recently in the rapid expansion of online and cloud storage. Given our exceedingly heavy reliance on hard drives, it's very, very weird that one piece of vital information still eludes us: How long does a hard drive last? According to some new data, gathered from 25,000 hard drives that have been spinning for four years, it turns out that hard drives actually have a surprisingly low failure rate."

over the last 20 years i've used almost every brand of hard drive and have had all the brands fail at least once. every single brand has had quality issues at one time or another

Only my personal experience but as for "power cycling" . . . I follow one basic rule.

If you turn it off every night (when you go home from work) . . . it'll work fine, and last five years . . . then you're in the danger zone.
If you LEAVE IT ON for weeks at a time and NEVER turn it off . . . it'll work fine, and last five years . . . then you're in the danger zone.
What you NEVER want to do is . . . run it for a year (like at a factory plant) then turn it off for a week vacation. You're toast. (In my limited experience of 28 years) . . . if you turn it off that week . . . there is a 75% chance . . . it'll never turn on again.

I don't know if the "grease" settles, or the metal binds . . . I just know if its been on a year . . . don't turn it off for more than an hour or two if you want it to continue to work.
