  • System for monitoring the throughput performance of a disk storage system
    Patent number: 5987400
    Abstract: In a disk storage drive having a CPU, a disk and an EEPROM, the CPU measures throughput performance. The CPU measures the throughput performance for a measured area provided on a data-recording surface of the disk, in response to a test command supplied from a host system. The measured area consists of three zones designated by a pointer stored in the EPROM. The CPU stores the throughput performance measured for the measured area, into the EEPROM, and updates the pointer so that the CPU may measure the throughput performance for the next measured area provided on the data-recording surface.
