Lol, sorry, made me think of the SanDisk Ultra Flair USB 3.0 64GB Flash Drive High Performance up to 150MB/s (SDCZ73-064G-G46).
They never mention that it writes at USB 2.0 speeds. Returned it.
I'm now very happily using the
Patriot 64GB Supersonic Rage Series USB 3.0 Flash Drive With Up To 180MB/sec- PEF64GSRUSB and
Patriot PEF128GSR2USB 128GB Supersonic Rage 2 Series USB 3.0 Flash Drive with Up to 400MB/Sec Read, 200MB/S Write

your mileage may vary, make sure you read the specs and look at benchmarks for comparison.
That being said, the brands I trust are Samsung, WD, and SanDisk
