Suggestion: rename Random SSD Seek to Random SSD Read

My understanding is that a sequential SSD read takes 1us and a random SSD read takes 100us. In the repository, "Random SSD Seek" should be renamed to "Random SSD Read" so you can compare it to "Sequential SSD Read" easily. Otherwise, users may think that to do a random SSD read, you first need to do a random SSD seek and then a sequential SSD read.
