摘　　要：分析了目前一些高速硬盘记录系统结构的优缺点;主张采用经济通用的高速数据采集卡、小型计算机系统接口(small computer system interface, SCSI)适配卡和SCSI硬盘构建的高速硬盘记录系统;指出在软件中用高级SCSI编程接口(advanced SCSI programming interface,ASPI)直接控制SCSI硬盘,以地址顺序递增的方式记录数据,可使数据的记录速度明显提高;最后给出了系统测试结果,其持续记录达到40 MB/s.The paper analyses the structure of some high-speed hard disk recording systems of these days and points out their advantages and disadvantages. It is proposed to construct high-speed data recording system using high-speed data acquisition card, Small Computer System Interface (SCSI) adapter card and SCSI hard disk for that they are all economical and universal. At the same time, the paper advances a method of using Advanced SCSI Programming Interface (ASPI) in software to direct control hard disk and access data in turn. In this way, the recording speed can be improved greatly. Then test results of the system are given. The sustained record speed can up to 40 MB/s.
