Database of Validated Disk Parameters
    for DiskSim v2.0


    For each disk listed in the table, a set of files is provided in a gzip'd tar file (using the common UNIX/linux utilities). By unpacking this set in the subdirectory named "valid/" in the unpacked DiskSim release tarball, one can simply run the script called diskname.runvalid to exercise the downloaded disk characterization with the included validation trace. The formats of the various files are the same as those included with the DiskSim 2.0 release. 

    With the exception of the last five parameter sets provided below, the disk parameters provided here were extracted automatically with the DIXtrac disk characterization tool.
