AMD and Seagate are teaming up to demonstrate the next-generation Serial ATA specification, dubbed “SATA 6Gbps”, the new spec will offer twice the disk-to-host bandwidth of the existing 3Gbps Serial ATA standard. Although the fastest Serial ATA hard drives on the market have a rough time maintaining transfer rates higher than about 110MB/s, they can typically push smaller burst transfers from their caches at over 250MB/s. Those caches are growing, with the latest desktop models packing 32MB memory chips. And let’s not forget solid-state drives like Intel’s X25-E Extreme, which has no problem sustaining over 200MB/s for reads and writes.
