I'm sorry, but 4MB is *NOT* a small file, and does literally nothing to simulate a world-world test. The reason that most people do a 4KB small file test is two-fold: 1) to simulate real-world usage such as browser caches, saving/updating documents, access your OS swap file, etc; and 2) flash memory uses a 32KB page/cell size, so it gives a world-world performance measure of those real-world writes. A 4MB file will be written as many sequential writes which is hardly a real-world scenario. Yes, you most definitely will have time when you're copying 4+MB files between drives, but it won't be nearly as often as writing small (<=4KB) files, especially considering your OS swap file will be using those small writes. That's also the reason the last test suite ran multiple tests from 0.5KB through 8192KB. That's really the only test you need to show.

4 MEGAbytes is a small file?
