Abstract
A method and system for data storage provides a digital fast-write storage device, a plurality of digital slow-write storage devices, and a controller. The digital fast-write storage device might be a solid state drive. The digital slow-write storage devices might be conventional rotational media drives. Typically, read operations are directed to the fast-write storage device. The slow-write storage devices provide redundancy by mirroring the contents of the high-speed storage device. Data on the slow-write storage devices is organized in stripes, allowing data to be written in parallel. The number of slow-write storage devices can be chosen to compensate for the speed differential on write operations. In some embodiments, the controller will represent the storage system as a virtual disk drive.
