Corsair claims world's fastest 128GB USB flash drive
Corsair Memory Inc. today announced what it claims to be the world's fastest 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 multi-level 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.
By comparison, the 8GB Iron Key USB flash drive, 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.
