Computerworld - Corsair Memory Inc. today announced what it claims to be the world's fastest a 128GB USB flash drive, the Flash Voyager GT. The newest Flash Voyager GT is based on a dual-controller architecture to achieve what Corsair said is single-level cell (SLC) NAND flash memory performance levels using less expensive and higher-density multilevel cell (MLC) NAND flash.
According to Corsair, the 128GB Flash Voyager GT can achieve read speeds of up to 32MB/sec. and write speeds of up to 25.6MB/sec. The limiting factor in throughput is the speed of the USB 2.0 bus -- a maximum of 480Mbit/sec. -- and any operating system overhead.
In comparison, the 8GB Iron Key USB flash drivers, which actually uses SLC flash memory, has a read speed of up to 30MB/sec. and a write speed of up to 20MB/sec. (Computerword's review of the 4GB Iron Key showed it had a read rate of 29MB/sec.) Flash drives with more memory tend to have better performance.
"High performance is a key requirement for super-high-capacity flash drives such as the 128GB Voyager GT, simply because it is able to store such a large volume of data," John Beekley, vice president of applications at Corsair, said in a statement. "The 128GB Voyager GT is nearly twice as fast as other high-capacity flash drives, which means less time waiting for your music, video or office files to copy to and from the drive."
