Over the last decade we have witnessed the relentless technological improvement in flash-
based solidstate drives (SSDs) and they have many advantages over hard disk drives …

In this paper, we describe the collection and analysis of file system traces from a variety of
different environments, including both UNIX and NT systems, clients and servers, and …

Although disk storage densities are improving impressively (60% to 130% compounded
annually), performance improvements have been occurring at only about 7% to 10 …

A flash memory device driver that supports a conventional UNIX file system transparently
was designed. To avoid the limitations due to flash memory's restricted number of write …

Configuring redundant disk arrays is a black art. To configure an array properly, a system
