Apparatus with reduced latency for master and slave storage devices

摘要

Disclosed is an information processing apparatus. The information processing apparatus includes a first hard disk drive, a conversion circuit and a signal control circuit. The conversion circuit is connected with the first hard disk drive to determine whether a second hard disk drive corresponding to a slave exists when the first hard disk drive serves as a master, and the determine whether a first control signal has a first logic level in a first predetermined time.
