The Supersonic Xpress has a great physical form, the innovative retractable design features a spring loaded back which snaps into place very satisfyingly, it's tempting to pop it in and out for no particular reason. In terms of performance the Xpress is below average across the board with the exception of an outstandingly high 4K read score of 14.2 MB/s. From a value perspective this drive is near the bottom of the pack, it has below average performance and is currently retailing at an above average price. [Jun '12USBFlashPro]
The 16GB Jumpdrive P10 decimates the existing sequential write speed records. With a sequential write speed of 161 MB/s the P10 is 52% faster than the current record of 106 MB/s which is held by Lexar's previous flagship USB 3.0 Jumpdrive Triton. As yet the P10 is still relatively new but Lexar have an excellent track record for reliability and the P10 is likely to fare well amongst the competition. Within the 16 GB category the P10 is currently the worlds fastest flash drive. That said, if your use case involves a lot of small file operations (most don't), then there are better alternatives available. [Aug '13USBFlashPro]
