With SSDs this is pointless. Why? Because it takes exactly the same amount of time to read two adjacent blocks of data or else to read two blocks that reside at different addresses on the "disk".
Awwww, I see now Frederik,
But I'm still a little bit confused on that. Lets say you have a SSD with four blocks, and they are full. then on day you decide to Delete/Uninstall a very large program, and that program lies in-between the first and fourth block leaving two
emptily blocks in-between the first and last block. Wouldn't it have to read the First Block of Information and then Jump to the last block to find the rest of the information leaving the two middle blocks empty, and wouldn't that take extra time???... and
when you install a new program it will look for the first empty block to write in Correct?... and after time wouldn't you have little bits of program information all over the different blocks?...
