Background on Laptop Hard Drives
Though all of our mobile hard drives provide great performance, some features may be more important for individual needs. If battery life is of highest importance, going with a 5400 RPM drive can save on power consumption. Choosing a 7200 RPM drive will give you better performance, but it will also shorten battery life.
Since they are all based on the 2.5 inch form factor (rather than their 3.5 inch desktop counterparts), each of these mobile drives are very light and can fit into extremely small spaces. They are also slower than the large desktop drives, though.
The alternative to hard drives is solid state drives, which are many times faster but much more expensive for the same amount of capacity. The price gap is dropping over time, so SSDs are becoming more and more preferred for us. For performance, reliability, and noise reduction, SSDs are really the way to go.
I wouldn't recommend using one of these as a boot drive, due to their relatively slow speed, but they are great for added storage capacity in a laptop or other computer where 2.5" drives are required. Some small network attached storage boxes use this size of drive, for example.
