The biggest trend that everyone's looking forward to is USB 3.0, of course! Super Talent has already released three SuperSpeed USB flash drives that take advantage of the new interface with reported speeds that are five to eight times faster than the fastest USB 2.0 flash drives. Expect more USB 3.0 drives from other manufacturers to follow shortly.
Another big development with flash drives is how hardware encryption is becoming more of a commodity than a luxury or enterprise feature, being built into flash drives from a range of manufactuers for as little as $20 USD. Drives certified against the FIPS 140-2 standard are almost as cheap, now available at the $60 USD price point from online retailers.
