Recently, storage systems have observed a great leap in performance, reliability,
endurance, and cost, due to the advance in non-volatile memory technologies, such as …

Multi-streamed SSDs can significantly improve both the performance and lifetime of flash-
based SSDs when their streams are properly managed. However, existing stream …

High-density Solid State Drives (SSDs) have to use Low-Density Parity-Check (LDPC)
codes to store data reliably. Current LDPC implementations apply multiple read-retry steps …

Performance isolation is critical in shared storage systems, a popular storage solution. In a
shared storage system, interference between requests from different users can affect the …

As data security has become the major concern in modern storage systems with low-cost
multi-level-cell (MLC) flash memories, it is not trivial to realize data sanitization in such a …

We consider a scene containing two independently and generally moving objects, viewed
by two general perspective views. Using matching points arising from both objects …

Copyback is an advanced command contributing to accelerating data migration in garbage
collection (GC). Unfortunately, detecting copyback feasibility (whether copyback can be …

Owing to the fast-growing demands of larger and faster NAND flash devices, new
manufacturing techniques have accelerated the down-scaling process of NAND flash …

Commodity solid state drives (SSDs) have recently begun involving the adoption of powerful
controllers for multichannel flash management at the page level. However, many of these …

Motivated by the needs to enhance the performance of garbage collection in low-cost flash
storage devices, we propose a victim block selection design to efficiently identify the blocks …
