The performance of PC solid-state disks (SSDs) as a function of bandwidth, concurrency, device architecture, and system organization

As their prices decline, their storage capacities increase, and their endurance improves, NAND Flash Solid State Disks (SSD) provide an increasingly attractive alternative to Hard Disk Drives (HDD) for portable computing systems and PCs. This paper presents a study of NAND Flash SSD architectures and their management techniques, quantifying SSD performance under user-driven/PC applications in a multi-tasked environment; user activity represents typical PC workloads and includes browsing files and folders, emailing, text editing and document creation, surfing the web, listening to music and playing movies, editing large pictures, and running office applications.
