Compared with primary storage,the storage capacity of a DASD is larger and the cost per bit stored is lower.although the access time of a DASD may be only a few milliseconds,primary storage,primary storage speed is thousands of timer faster.different DASDs provide different levels of cost and performance.

与主存储器相比，DASD的存储容量更大，每存储位的花费更低。尽管DASD的存取时间只为几毫秒，而且主存储器的速度比之快几千倍。不同的DASD其成本和性能的等级也不同。
