Plextor M6V SSD (256GB) Review – A Solid Value Entrant

PCMARK VANTAGE X64 HDD SUITE

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

PLEXTOR M6V VANTAGE TOTAL SCORE

The Plextor M6V achieved a total score of 81849, which is a very good score. Out of all the benchmark tests ran throughout the HDD suite of PCMark Vantage, the highest transfer speed recorded was 460 MB/s when importing digital photos in Windows Photo Gallery..

WORKLOAD CONSISTENCY TESTING

For our last benchmark, we have decided to use PCMark 8 Extended Storage Workload in order to determine steady state throughput of the SSD. This software is the longest in our battery of tests and takes just under 18 hours per SSD. As this is a specialized component of PCMark 8 Professional, its final result is void of any colorful graphs or charts typical of the normal online results and deciphering the resulting excel file into an easily understood result takes several more hours.

There are 18 phases of testing throughout the entire run, 8 runs of the Degradation Phase, 5 runs of the Steady State Phase and 5 runs of the Recovery Phase. In each phase, several performance tests are run of 10 different software programs; Adobe After Effects, Illustrator, InDesign, Photoshop Heavy and Photoshop Light, Microsoft Excel, PowerPoint and Word, as well as Battlefield 3 and World of Warcraft to cover the gaming element.

  • PRECONDITIONING -The entire SSD is filled twice sequentially with random data of a 128KB file size. The second run accounts for overprovisioning that would have escaped the first;
  • DEGRADATION PHASE – The SSD is hit with random writes of between 4KB and 1MB for 10 minutes and then a single pass performance test is done of each application. The cycle is repeated 8 times, and with each time, the duration of random writes increases by 5 minutes;
  • STEADY STATE PHASE – The drive is hit with random writes of between 4KB and 1MB for 45 minutes before each application is put through a performance test. This process is repeated 5 times;
  • RECOVERY PHASE – The SSD is allowed to idle for 5 minutes before and between performance tests of all applications. This is repeated 5 times which accounts for garbage collection; and
  • CLEANUP – The entire SSD is written with zero data at a write size of 128KB

In reading the results, the Degrade and Steady State phases represent heavy workload testing while the recovery phase represents typical consumer light workload testing.

PCMARK 8 RESULTS

As you can see, performance is recorded in terms of Bandwidth and Latency. Bandwidth (or throughput) represents the total throughput the drive is able to sustain during the tests during each phase. Latency, at least for the purposes of PCMark 8, takes on a different outlook and for this, we will term it ‘Total Storage Latency’. Typically, latency has been addressed as the time it takes for a command to be executed, or rather, the time from when the last command completed to the time that the next command started. This is shown below as ‘Average Latency’.

PCMark 8 provides a slightly different measurement, however, that we are terming as ‘Total Storage Latency’. This is represented as being the period from the time the last command was completed, until the time it took to complete the next task; the difference of course being that the execution of that task is included in ‘Total Storage Latency’. For both latency graphs, the same still exists where the lower the latency, the faster the responsiveness of the system will be. While both latency charts look very similar, the scale puts into perspective how just a few milliseconds can increase the length of time to complete multiple workloads.

AVERAGE BANDWIDTH (OR THROUGHPUT)

These results show the total average bandwidth across all tests in the 18 phases. In this graph the higher the result the better.

AVERAGE LATENCY (OR ACCESS TIME)

These results show the average access time during the workloads across all tests in the 18 phases. In this graph the lower the result the better.

TOTAL STORAGE LATENCY

These results show the total access time across all tests in the 18 phases. In this graph the lower the result the better.

The Plextor M6V is pretty average when we look at consistency and latency. In consistency testing it fell short to the Samsung 850 Evo and the ADATA Premier SP550. This drive compared very similarly to the Sandisk Ultra II.

    Thanks for the heads up on this. It looks worth a shot if is comes down from the current Amazon and Egg price offerings. I’m not going to hold my breath though since I don’t think of the aggressive pricing you hope for as being a part of the usual Plextor game plan.

    Any idea what the P/E numbers are on these 15nm toggle NAND ?

    • Benjamin Hojnik

      Probobly 2000-3000 p/e.

      Although p/e is not the only measure of endurance.
