Using Intradisk Parallelism to Build Energy-Efficient Storage Systems

Server storage systems use numerous disks to achieve high performance, thereby consuming a significant amount of power. This paper discussed the intradisk parallelism that can significantly reduce such systems' power consumption by letting disk drives exploit parallelism in the I/O request stream. By doing so, it's possible to match, and even surpass, a storage array's performance for these workloads using a single, high-capacity disk drive.
