Abstract
A data storage system is described which allows data storage devices with different characteristics, such as differing data rates and transfer speeds, to be connected, and intermixed, along a single data and communication link. The data storage system comprises a storage controller, a first data storage device, a second data storage device, and a data and communication link coupled therebetween. The storage controller transfers data to and from the first data storage device using data locations within the data and communication link to transfer a data byte, a parity location to transfer the associated parity bit, and a communication signal location to transfer a data clocking signal. The storage controller further transfers data to and from the second data storage device using the data locations to transfer a data byte and the parity location to transfer a data clocking, or a data strobe, signal. The storage controller also provides cyclic redundancy checking (CRC) to detect data transmission errors to the second device type, since the parity bit is no longer used to detect these errors.
