Abstract
MEMS-based storage device is a new candidate of storage device for pervasive applications which requires large volume of storage. Because of its attractive features such as high-bandwidth, low-power consumption, and low cost compared with hard disk, the storage performance could be significantly improved by adopting MEMS-based storage devices, especially when employing new request scheduling algorithm and data placement A new request scheduling algorithm is explored for MEMS-based storage devices in this paper, which is named parallelism-aware and zone-based shortest positioning time first (PZSPTF). And a new data placement scheme is also introduced, with which the storage area is divided into 2 parts according to 2 file classes, and the files of same class will be stored in the same part. Experiments show that the new PZSPTF algorithm improves the performance of MEMS storage by 7.83% to 18.51% compared with the widely acknowledged request scheduling algorithm FCFS (first-come, first-served).
