The Buffalo DriveStation DDR is a high-performance external USB 3.0 hard drive with a large 1GB cache for accelerated file transfer speeds. All SATA HDDs have a native cache inside (normally ranging from 16 to 64 MB), which is used to accelerate and buffer files before move onto, or after they have been read from, the magnetic surfaces. Buffalo's DDR desktop drive uses standard HDDs with cache; however it adds an additional 1GB DDR3 on the USB controller PCB.
