V200 is a very bad SSD, use v100 or V series only. THe V200 has defective firmware, and onl offeres 30-50MB/ps write speed. the older versions perform better. And the 64GB model is very slow. So stay away from V200 until Kingston releases new firmware. THey said it should be out sometimes in Jan. They could of stuck with the same toshiba controller in the V100, and they wouldn't of had this problem, but instead they released a new product without proper testing. And the firmware is v1.0. THey said 'its in its baby state'.
