Do laptop HDDs last longer than desktop HDDs?

Solution
Laptop hard drives tend to be more rugged than desktop hard drives simply because they're smaller. The strength of a material goes as the square of its dimensions, but its mass goes as the cube. So if you double the size of something, its strength increases by 4x, but its weight increases by 8x. So if you were to (say) drop the computer on the ground, the platters and read-write heads of the smaller drive would have an easier time resisting the forces.

The drawback is that laptop drives are slower. Many laptop drives are still 5400 RPM. And even if you have a 7200 RPM laptop drive, its outer circumference is only about 70% that of a desktop drive. So at the same level of technology (same areal density), a 7200 RPM laptop drive...
It depends on brand of laptop and software on it as well. For eg. DELL Laptops HDD lasted me as long as 5-7Yrs but HP Laptops HDD lasted hardly 2-3Yrs.

But when compared to HDD of desktop laptop HDD have shorter life as laptop is portable and always on move so it causes problem when internal components gets damaged due to sudden jerks or hard movements.

But if you plan on using it as desktop which means placing it on table and not moving it much it should last long.

So at the same level of technology (same areal density), a 7200 RPM laptop drive will only be able to read/write 70% what a 7200 RPM desktop drive can read/write during a single rotation. Couple this with the lower overall capacity, and I wouldn't use a laptop drive in a desktop unless I had to. Use either a SSD or desktop HDD.

I want more freespace & airflow inside my case. The desktop HDDs are bulky and look ugly.
