Thank you for the article - this gives some insight into how hard disk manufacturers can make claims for X hours MTTF and similar. And to make general estimates as to the life span of disk drives in general.
Veering slightly off-topic, I have become an exponent for Seagate hard drives - any company who proudly advertises "5 year warranty" on the packaging of their mass-market consumer IDE and SATA drives (whilst most other major manufacturers only give 1-3 years) gets my business. It's not necessarily about whether I'd really have to make a warranty claim (WDC honored such a claim for me back in 2002 with minimal fuss), but rather that they have such a high level of confidence in their craftsmanship as to even advertise such a warranty.
Sorry if this violates any rules for "plugging" a particular brand. But, I'm reminded of what the salesperson at Fry's told me about why Seagate warranties their drives so well: They re-engineered the spindle bearings and motor assembly - the critical points of the disk drive which the salesperson said were most often the cause of total drive failure. Any other ideas/comments?
