Fantastic Stick!

The Sandisk Extreme 64 U3 is the fastest drive I've ever had in my fingers. The write speed is 150MB with / sec (NTFS to USB3 measured with h2testw) sensational. Only the Lexar Triton comes with 123MB / sec reasonably with, is here but clearly hotter.
The read speed is even higher.
Only complaint is the sliding mechanism. The annoying simply upon insertion of sticks, but is no reason for star deduction. Therefore, 5 star with distinction! ;-)
