A. For sequential services, the cache capacity does not need to be large, it only needs to meet the I/O consolidation requirements

B. For write business, more cache capacity means higher write consolidation rate, write hit rate and better access order

C. For the read business, more cache capacity means a higher read hit rate

D. For random services, a larger cache capacity means a better order of access to disks, which leads to improved performance

A. True

B. False
