This could have been a serious contender in the high speed USB 3.0 arena. On paper at least, with 260/220 MB/s read/write speeds, this drive would have had the highest sequential speeds we have seen to date on a 64GB drive. The GT Turbo was delayed by several months by Corsair, and when finally released it proved to fall far short of the advertised headline speeds. In reality it can only write at around 80 MBps and has an extremely weak 4K Random write speed. Corsair have offered refunds to the multitude of unhappy customers that bought this drive in anticipation of it setting new speed records. There are far faster drives available. [Aug '13 USBFlashPro]

Because of its fantastic headline read/write speeds, there is often a lot of interest in this drive. It's not available in 16GB so I couldn't include it in the standardized tests. Quickly looking at the 64GB Kingston HyperX 3.0 (manuf.) claimed seq r/w speeds 225/135 @ £78 or $100. Compared to the November leader - Sandisk Extreme 64GB version (manuf.) claimed r/w 190/170 @ £45 or $79. The extreme is significantly better value, and has much much faster 4K write speeds. [Nov '12 USBFlashPro]
