Do 2.5" Hard drives not last as long as 3.5" ones?

Would it be a bad idea to use a 2.5" drive in a machine that's always on? I get the impression that despite assertions of high MTBF's in the spec sheets they are actually designed to only last a few thousand hours because thats all your average laptop will be used for anyway, few hours a day for 2-3 years.
