Zusammenfassung:Shingled Magnetic Recording disks overlap tracks to increase storage density, and thus require a special processing to achieve unrestricted random sector updates without data loss. The Shingled File System (SFS) is a host-side level solution to this problem and allows more efficient optimizations compared to a disk firmware based approach. Experimental results show that no overhead is incurred for large file workloads, making SFS a suitable solution for video processing devices such as personal video recorders and set-top-boxes.
