Plextor M5 Pro Xtreme SSD Review (256GB) – 100,000 IOPS and Excellent Performance


You may not see this for long (and its definitely not common) but you get a free-bee simply for reading!  Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility.  Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and utilize in our benchmark testing.

Plextor Extreme Anvil Incomp

In conducting our Anvil benchmarks, we were a bit disappointed that the IOPS did not reach specifications of 100,000, so we went a bit further and increased the queue depth of the tests for both read and write IOPS:

Plextor Xtreme QD64 Read IOPS 99011Plextor Extre Write IOPS 84150In doing this, we learned that IOPS actually improved as we increased the QD, noting that we are at read QD64 and write QD32.  Some have wondered if the M5 Pro Extreme would perform in an enterprise environment with higher queue depths and this pretty much tells the story.


The SSD Review uses benchmark software called PCMark Vantage x64 HDD Suite to create testing scenarios that might be used in the typical user experience. There are eight tests in all and the tests performed record the speed of data movement in MB/s to which they are then given a numerical score after all of the tests are complete. The simulations are as follows:

  • Windows Defender In Use
  • Streaming Data from storage in games such as Alan Wake which allows for massive worlds and riveting non-stop action
  • Importing digital photos into Windows Photo Gallery
  • Starting the Vista Operating System
  • Home Video editing with Movie Maker which can be very time consuming
  • Media Center which can handle video recording, time shifting and streaming from Windows media center to an extender such as XBox
  • Cataloging a music library
  • Starting applications


The M5 Pro Xtreme finished PCMark Vantage Suite Testing with a Total Score of 71799 which was totally unexpected.  This is the highest result we have seen with the newer 19nm memory in play and very encouraging.  Quite frankly, it fared well above the M5 Pro which contained the same firmware so the significant jump still cannot be explained, although a number of test repeats were conducted with similar results.


The following Chart shows the placement of the Plextor M5 Pro Xtreme SSD amongst the best of the best.  Keep in mind that this hierarchy has ONLY been determined by PCMark Vantage Total Score placement.

    Why is the 256GB OCZ Vector that was reviewed by this site missing from the Top 25 SATA 3 SSDs in the Vantage Chart?

    Your link to Amazon actually shows the Extreme, with shipping, is a little more expensive than the Pro, which ships for free.

    I think Les you should definitely update yours “SATA 3 SSD PCMark Vantage Point Total” in “SSD Benchmark Locker”.
    People could draw the wrong conclusions from the current results

    Still looks like if a fella wants the overall fastest, the Samsung 840 Pro is it. What’s a few dollars?

    I have to say, for the price point of this drive, it performs very well. I have been a longtime user of OCZ products as I have never had any problems with them and their Vector line is incredible. With that said, I am currently using the Plextor M5 Pro Xtreme and the performance is exactly as stated in this review. It is a solid drive and I recommend anyone who wants to save a bit of money and still have great performance to get this drive.

    I’d like to follow up with another comment about this drive. I have continued to be impressed with this hard drive. After reviewing many different drives and testing their performance, this one still continues to impress. Let’s be realistic here. You take the top 5 best drives, which Plextor M5P is apart of, and put each one into identical setups you are highly unlikely to see any different in boot speed or how fast programs open and close. It is simply a great drive and a great price. Do yourself a favor, and purchase it. I couldn’t be happier.
