....rates. Mechanical disks that read several heads at once are available from such vendors as CDC and Fujitsu [3, 4] Other manufacturers have introduced, or are at least investigating, so called storage arrays that assemble multiple drives into a single logical device with enormous throughput [5, 6]. Unlike multiple head drives, storage arrays can be scaled to arbitrary levels of parallelism, though they have the unfortunate tendency to maximize rotational latency: each operation must wait for the most poorly positioned disk. As an alternative to storage arrays, Salem and Garcia Molina have ....
