....delayed [17, 20] Finally, unlike magnetic disk, flash memory requires explicit erasure before a segment can be overwritten, a slow operation that can wear out the medium and must operate on a segment at a time. One solution to these problems is to use a log structured file system like LFS [18, 29], in which new data does not overwrite old data but is instead appended to a log. This allows erasures to be decoupled from writes and done asynchronously, thus minimizing their impact on performance. A flash file system also needs some way to ensure that no physical segment is cleaned especially ....

....a delay measured in seconds as opposed to the tens of milliseconds of delay expected from a spinning drive 2 . Major power savings can be achieved by applying an aggressive disk spindown policy; a simple short time out drive spindown policy can achieve close to optimal performance [Kester94][Klostermeyer95]. These results have been independently verified in various trace driven studies [Douglis94] Current disk products use an idle time of two seconds as the appropriate spindown threshold. Figure 1 shows the standard transition diagram for a power optimized disk drive. 1. Newly developed small form ....
