For real world usability this is currently the best 64GB flash drive (superseded by the Ventura Ultra - 2014). It has a very balanced performance profile with an exceptional 4K random write speed. The 16GB version of the Extreme is currently the value leader in the USB 3.0 flash drive shootout. At present there are no viable alternatives to the 64GB Extreme in fact the Corsair voyager GT turbo is the only drive on the horizon that may challenge the Sandisk any time soon. There are however several reports (Newegg, Amazon) of compatibility issues with this, the 64GB version (other versions are fine), so if you do go for the 64GB version, don't throw the receipt away in a hurry. [Feb '13 USBFlashPro]

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]
