Super Talent Technology, a leading manufacturer of Flash storage solutions and DRAM memory modules, today announced a new USB 3.0 flash drive, the USB 3.0 Express DUO 2-CH. Featuring a cap-less industrial design, the USB 3.0 Express DUO 2-CH, now features a black "piano finished" plastic housing that twists to reveal and conceal the USB 3.0 port inside.

The 2-channel design of the Express Duo 2-CH can top over 67 MB/s when plugged into a USB 3.0 port, yet remains fully-backward compatible to USB 2.0 and for about the same price. This new flash drive also comes pre-installed with Microsoft Security Essentials, real-time protection for your home PC that guards against viruses, spyware, and other malicious software. Our USB 3.0 drive makes it easy to install this software on all of your PCs.



"Here is a USB 3.0 drive that performs, yet stays on budget. There is simply really no reason to buy a USB 2.0 flash drive anymore" CH Lee COO of SuperTalent.

...and this is supposed to be what, faster than the other one? That one was at least supposed to be 23MB/s write and 67MB/s read. Not sure how this being 18MB/s write and 69MB/s read is any better...

In my tests of the 8GB Express DUO on USB2.0, I was lucky to get 11MB/s write...

This is because Supertalent has essentially put a SATA SSD onto a USB interface in a stick form factor.

All of their USB 3.0 drives need to be treated with the same alignment rules that apply for SATA SSDs.

If you use diskpart and type:

list disk (look for the number next to the ST drive)
select disk <number from above>
list partition

You'll see the offset to be 31KB which is the sector 63 offset (bad on Supertalent's part, they should not be using this offset from the factory). If you wipe the partition table and create a new partition with the Vista/7 standard offset of 1024KB it should get better speeds.
