7200 vs 5400 rpm and Lifetime
Read something a few days ago about 7200 rpm drives having shorter lives than 5400 rpm. Does anyone here have experience along these lines. Can't remember where I saw it. Thinking about WD 40g 7200.

i wouldn't worry about it honestly. a 7200 rpm hard drive will hold up fine over time... plus you'll be very happy with the performance increase if you're on a 5400 rpm drive currently.

as long as it isnt one of those ibms that overheats it should last long..--Jacob--

you mean if i got a seagate 7400 rpm drive, i will have a sound sleep at night without worrying about it? I would like to buy a 40 Gb (hopefully) 7400 rpm and i guess I will have to erase IBM on my list.

ALL of the newer hard disks these days have lives in hundreds of thousands of hours (and some in the million hours range). Since there is only 8760 hours in a year generally you are talking of decades before failure becomes an issue.They say technology slows down for no one. I know it outruns my wallet. I figure its because my wallet isn't light enough yet.

The MTBF rating on a drive is a statistical rating. If you take 1000 drives with a MTBF of say 100,000 hours and run them continuously for a year, more than likely you find at least one failed. If you take the same drives and cycle the power at least once a day (simulating quite a few home and laptop users), you will likely find several failed at the end of that year. They don't actually test drives for 100,000 hours to see if they work for that long. They take a batch of drives and run them for a period of time, see how many failed, and make a statistical estimate to get the MTBF.
As for the lifetime differences between different RPM drives, I have heard some drives (Seagate, Maxtor) have consistently longer lifetimes than others at the 7200 RPM speeds. Some manufacturers are skimping on the QA aspects of their drives, just to get more bigger and faster drives to market faster.
