This page contains 55 trace files collected to study modern, multimedia workloads. The applications include a web browser, viewing photo galleries and streaming media recorders and players of various bitrates. The trace files were collected using a Linux 2.6 kernel with an ext3 journalling filesystem, and captured at the block driver level.

The trace files are stored in plain text, one request per line, with the fields separated by whitespace. The fields of the trace file:
| Field | Value |
|---|---|
| 1 | Timestamp, in seconds, with 6 decimal places |
| 2 | READ or WRITE |
| 3 | Block number on disk |
| 4 | Number of blocks requested |
| 5 | Block offset within inode** |
| 6 | File path** |
** - Not all blocks contain file data. For requests which access filesystem structures or other non-file data, these fields are set to a dash.
