摘要：
As the next main stream of HDD techniques, Shingled Magnetic Recording (SMR) drives have unique features different from conventional disk drives, e.g., append only (sequential) write, indirect address mapping and garbage collection. Batch write process is specially designed to plenarily utilize the sequential write property to amend the SMR drive performance. However, there is no dedicated analytical model available for the performance of SMR drive so far. In this paper, an analytical model is built based on queuing model to fill the gap and utilized to provide plausible guidance of SMR drive design.
