Improving the instantaneous writing speed to hard disk by alternately buffering

The hardware design of a computer interface card which can improve the instantaneous writing speed to hard disk by means of memory image alternately buffering is introduced, and the precise coordination with the software and hard disk initialization based on the detail analysis of the writing process to hard disk is also given in this paper. In fact, since not only the average but also the instantaneous writing speed has been enhanced, the method is generally valuable to any rapid real-time storage of measurement data. It has been applied to a CAMAC remote measurement system for storing the large capacity and high throughput measurement data.<>
