Optimizing MEMS-based storage devices for mobile battery-powered systems
Mohammed G. Khatib, Pieter H. Hartel
Article No.: 1
DOI: 10.1145/1714454.1714455

An emerging storage technology, called MEMS-based storage, promises nonvolatile storage devices with ultrahigh density, high rigidity, a small form factor, and low cost. For these reasons, MEMS-based storage devices are suitable for...

NCQ vs. I/O scheduler: Preventing unexpected misbehaviors
Young Jin Yu, Dong In Shin, Hyeonsang Eom, Heon Young Yeom
Article No.: 2
DOI: 10.1145/1714454.1714456

Native Command Queueing (NCQ) is an optimization technology to maximize throughput by reordering requests inside a disk drive. It has been so successful that NCQ has become the standard in SATA 2 protocol specification, and the great majority of...

FRASH: Exploiting storage class memory in hybrid file system for hierarchical storage
Jaemin Jung, Youjip Won, Eunki Kim, Hyungjong Shin, Byeonggil Jeon
Article No.: 3
DOI: 10.1145/1714454.1714457

In this work, we develop a novel hybrid file system, FRASH, for storage-class memory and NAND Flash. Despite the promising physical characteristics of storage-class memory, its scale is an order of magnitude smaller than the current storage device...
