You wouldn't normally think of video playback as part of a content creation workload, but it's actually a very fundamental task. In order to edit a video file, you have to know what you're editing. So, in this trace, we play back a segment of an unprotected Blu-ray rip (~30 GB).

The workload here consists almost exclusively of sequential reads at a queue depth of one. However, 96% of all operations are 64 KB transfers. That's interesting because every other multimedia-related activity is dominated by 128 KB transfers.

I/O Trends:

  • 99% of all operations occur at a queue depth of one
  • 98% of all data transferred is sequential
  • 96% of all operations are 64 KB in transfer size
