That is an interesting observation. But it really depends upon the firmware used on the device. Not all SSDs operate the same and there are wide variations in implementation and resulting performance. Some vendors improve performance by aggressively making freed space available for rewrite. Support from the trim[1] command is critical for this function. (In short, you want it.) Also accessing any deleted blocks may require low level device specific diagnose instructions. So it is also possible that widespread use of SSDs in the future may make it increasingly more difficult to recover deleted files. Bob [1] http://en.wikipedia.org/wiki/TRIM
