There's no point to defragging one. The lesser reason is the nature of NAND flash: there's a limit to how many times you can write to a cell before it becomes unusable. (That limit is about 100,000 writes.) The circuitry in the controller is designed to transparently migrate the data off failing cells to good ones and mark the failing ones unusable, so in practice you would see a gradual degradation, but you are likely to replace the device long before you reach the point of even noticing that sort of wear. The bigger reason is that on a flash drive or SSD, there are no moving parts. It's a specialized form of memory, and any part of the storage can be accessed in the same amount of time. Given that, why bother defragging? It won't make any difference in performance, but will marginally increase wear on the drive. ______ Dennis https://plus.google.com/u/0/105128793974319004519 ------------------------------------------------------------------------------ Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!
