No, don't bother. It's a completely pointless exercise. The fact that
it's not liable to kill your SSD through excess writes these days is
pretty orthogonal.
Recall that the point of defragging was to organise files into
contiguous streams so that a spinning disk read-head wouldn't need to
jump all over to get the file. Now consider a flash-based system where >changing which block you're reading from has no difference in time cost
no matter where the block is on the device address space - not to
mention that there are three layers of mapping in between where the OS
thinks a file is and which physical cells it's actually on so *Windows >doesn't even know what it's moving around*.
Leave this shit to the filesystem driver.
