Chip advance could boost thumb drive speed by 50% Oct 12th 2013, 17:51, by Lucas Mearian, Computerworld Silicon Motion Technology last week announced it has begun shipping USB drive manufacturers samples of a new USB 3.0 controller chip for flash drives that could boost their performance by up to 50 percent. The company said the new SM3267 integrated controller is expected to deliver up to 160 megabyte-per-second read times and 60 megabyte-per-second write speeds through a single channel; that would be a 30 percent to 50 percent performance improvement over today's USB 3.0 flash drive technology. Even though the USB 3.0 specification has the capability to support 4.8Gbps throughput speeds, the speed of a USB 3.0-enabled flash drive is dictated by the speed of the accessing flash devices in the drive. Today, most consumer-USB 3.0 flash drives support about 100MB/s read speeds. "We are pleased to announce that SM3267 has received design-ins from most of our current USB controller customers, including many top-tier OEMs, and we expect SM3267-based USB 3.0 flash drives will be commercially available starting in the fourth quarter of 2013," Wallace Kou, CEO of Silicon Motion, said in a statement.
