Installing SSD to boost laptop performance

Is there a way to calculate the increase in performance you might expect by installing SSDs in laptops for specific business applications?

It depends on how often the application writes and reads to disk. Higher reads greatly benefit from SSDs. High writes do not. Random I/O benefits from SSDs, sequential I/O does not. If the laptop has many applications running concurrently with frequent swapping out of memory to disk, SSDs provide noticeable and significant performance improvement.  But really, there is no definitive answer. Calculations are basically simulating the environment. Few simulators get all (or even most) of the variables correct. The one application that always benefits from SSDs is the boot.
