1) The answer is yes in the sense that each cell has a limited amount of total cycles. The other answer is that it doesn't matter because you life expectancy is so long that it won't make a real difference anyway. 2) Fragmentation does not have any effect on a SSD so no Defrag utility out there is going to be set up for it. Defragging is done so that two main things happen. 1) the files are not spread far apart physically on the HDD so that the needle does not have to move very much when reading. 2) It moves the files as far to the outer edge of the drive as possible because the spin speed is faster out there and subsequently so are the search times. A SSD does not spin so it does not have faster seek times in any physical area. A SSD also has no need to keep files grouped because the search time from any single cell to any other single cell is the exact same. I hope that all makes sense.
