For real world usability this is currently the best 64GB flash drive (superseded by the Ventura Ultra - 2014).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]

The Mushkin Ventura Ultra USB 3.0 has a Sandforce controller coupled with MLC NAND. This combination produces mediocre results for an SSD but for a USB flash drive its small file 4K performance is staggering. Comparing the Ventura Ultra and Sandisk Extreme shows that for small file IO the Ventura is around 200% faster than the Extreme. The Extreme has faster peak write speeds but overall the Ultra leads by a whopping 72%. The Ultra is a great choice for hosting Operating Systems or for use as boot media (check mobo. compat.) where its small file performance and low access times will reduce load times by orders of magnitude. Thanks to its exceptionally reasonable pricing, the Ultra topples the Extreme as my top USB pick for both value for money AND overall performance. [May '14 USBFlashPro]
