Read the document supplied as "evidence" for the Travelstar drives. I think it's a big crock.
Specifically, the document states this:
"Service life of the drive approximately 5 years or 20,000 power on hours, whichever comes first under the following assumptions:
- Less than 333 power on hours per month
- Seeking/Writing/Reading operation is less than 20% of power on hours.
This does not represent any warranty or warranty period." (Travelstar Disk Drive Spec. pg. 31)
I interpret this to be a simple mathmatical calculation: you get about 5 years out of the drive if you only use it 333 hours a month (11 hours a day). Otherwise, you will get about 20,000 power on hours (2.5 years) assuming the drive is only reading/writing/seeking for 20% of that time. It's a MTBF approximation, and it gives 2 separate figures depending on usage. I think that's reasonable, obviously the lifetime of the device is going to change depending on it's usage.
Also of note, I don't even think the Deskstar is comparable to the Travelstar, the Tstar is a 2.5" drive that operates between 4200 and 5400 RPM. Seems to me that if that's the best they can do for "evidence" they don't have much of an argument.
