File systems treats Flash storage device as a traditional storage media with their logical address. However inside the Flash storage device, Flash Translation Layer (FTL) remaps logical address to physical address to hide physical limitation of Flash memory cells. Due to the address translation, intentional logical separation of file system’s layout does not directly applied to physical separation. As a result, the separate-intended file systems’ requests are mixed in physical location, which degrades write throughput, as well as Flash’s lifecycle. In this paper, we propose virtually separable Block management scheme for Flash storage system by introducing new common command interface and separable Block management in FTL. The experimental results show that the proposed scheme increases IO performance, as well as reduces flash-internal overhead.
