Some file formats are more compressible (wav more than mp3) but compresible itself means that the data has a lot of repeating patterns in it that can be substitutes for shorter patterns, or represented in a more compact form.
ie; for an image of 100 by 100 pixels of all the same color, its more efficient to store the image as "100 by 100 of color code" than color code, color code, color code etc... 10000 times.
I have two sandforce drives, and on a practical note, in day to day work, they are much faster than HDD and almost no one would notice the difference in compressed vs, uncompressed files unless they were benchmarking.
