Almost every part of computers have evolved rapidly over the past few years, with the exception of conventional hard disks. The performance of processors, graphics cards and other components has increased significantly, but the speed of hard disks has been a bit stagnant. Buffalo attempts the break the mold with its new DriveStation DDR3, an external hard disk with USB 3.0 and 1 GB of DDR3 RAM.
The performance of your average hard disk feels slow when you compare it to an SSD for example. Manufacturers such as Western Digital and HGST are working hard on new storage technologies, but the fruits of their labor are still far off in the future. One promising combination is putting SSD cache in a hard disk, something we saw recently in the Seagate SSHD.
