We introduce new methods to replay intensive block I/O workloads more accurately. These methods can be used to reproduce realistic workloads for benchmarking, performance validation, and tuning of a high-performance block storage device/system. In this article, we study several sources in the stock operating system that introduce uncertainty in the ...

Shingled Magnetic Recording (SMR) is a new technique for increasing areal data density in hard drives. Drive-managed SMR (DM-SMR) drives employ a shingled translation layer to mask internal data management and support block interface to the host software. Two major challenges of designing an efficient shingled translation layer for DM-SMR ...

Shingled Write Disks (SWDs) increase the storage density by writing data in overlapping tracks. Consequently, data cannot be updated freely in place without overwriting the valid data in subsequent tracks if any. A write operation therefore may incur several extra read and write operations, which creates a write amplification problem. ...

Shingled write disk (SWD) is a magnetic hard disk drive that adopts the shingled magnetic recording (SMR) technology to overcome the areal density limit faced in conventional hard disk drives (HDDs). The SMR design enables SWDs to achieve two to three times higher areal density than the HDDs can reach, ...
