Question: Suppose that you have a 256 GB solid state drive that the operating system and drive both support the TRIM command. To evaluate the drive, you do an experiment where you time the system's write performance for random page-sized when the file system is empty compared to its performance when the file system holds 255 GB of data, and you find that write performance is significantly worse in the latter case. What is the likely reason for this worse performance as the disk fills despite its support for TRIM? What can be done to mitigate this slowdown?
