NAND flash memory-based storage devices are becoming an attractive storage solution for multimedia storage servers because they afford several advantages including fast read access speed and low power consumption. Multimedia storage devices differ significantly from traditional storage devices in that the user files are accessed in a sequential read manner while metadata are updated frequently. In...
Solid-state drives (SSDs) based on NAND flash are widely used for various server applications. Multimedia storage devices differ significantly from traditional storage devices in that the user files are accessed in a sequential read manner while metadata are updated frequently. In this paper, we propose a new flash translation layer (FTL) scheme called the filtering FTL (FFTL) for multimedia storage...
NAND flash-based storage systems such as solid-state disk (SSDs) are becoming an alternative secondary storage solution for various applications. In flash-based storage systems, an intermediate software layer called a flash translation layer (FTL) is usually employed to hide the erase-before-write characteristics of the NAND flash memory. In FTL schemes, garbage collection is the major factor limiting...
NAND flash memory based SSDs (solid state disks) have become an alternative storage device for future computer systems. Legacy operating system functionalities like file system and virtual memory system should be carefully re-designed since flash memory cannot be overwritten unless erased in advance. In this paper, we study the performance of garbage collection schemes when flash memory is used as...
Flash memory has become an alternative storage device for future computer systems. Legacy operating system functionalities like file system and memory system should be modified since flash memory cannot be overwritten unless erased in advance. In this paper, we study a new Linux swap system considering flash memory as a swap storage. Especially we focus on the garbage collection performance and reduce...
