text: Final Words - Plextor Updates The Firmware on M5 Pro: Promises Increased Performance, We Test It
  Despite Plextor's reliability, I'm not very comfortable with the high IO latency in the M5 Pro. I would rather have slower peak performance if it translated to more consistent overall performance as the end user is not going to notice the peaks but is definitely going to notice the hiccups caused by frequent, high maximum latencies.
