Verfahren zur Datenspeicherung auf und Datenwiedergabe von mehreren Platten

The invention relates to a process of storing data on, or retrieving data from, a plurality of disks (15). In one embodiment the process uses up to four commercial disks (15) in parallel to increase bandwidth and capacity. To store data onto the disks (15), the data in the main memory is divided into segments numbered modulo 4, and each disk (15) then accesses and stores the same numbered segments. There is no master disk, and each disk (15) stores data asynchronously at its own speed. The system is transparent to the user in that it appears to be one disk. For retrieval from the disks (15), each disk (15) supplies its segments, which are then assembled in memory.
