The answer to many questions like this is, “it depends”. When people compare storage media, they usually check megabytes per seconds, but to be honest it is only applicable if you are doing large block reads and write.
But in case of software development, where a number of different files need to be read and write to compile an application, then the number of I/O operations per second need to be checked as it is a better indicator to analyse overall performance.
Although, it is up to you to figure out whether the performance differences give a good reason for the additional costs.
