Plextor M6S SSD Review (256GB) – Strength in a New Marvell SSD Controller Offering

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 M6S 256GB PCMARK VANTAGE RESULTS

The Plextor M6S 256GB SSD reached a Total Score of 74335 points with a high transfer speed of 400MB/s while testing in Windows Media Center and 6 of the 8 tests resulted in SATA 3 transfer speed results.  This result is definitely in the upper tier of our Total Score results as seen here:

REPORT ANALYSIS AND FINAL THOUGHTS

When we think of SSDs, Plextor enjoys a solid reputation for quality and customer service, many knowing first hand that Plextor SSDs are amongst the most dependable in the business.  This is the result of a very solid business practice where, unlike so many other manufacturers, the dollar doesn’t come first when choosing components for their SSDs.  Plextor sticks to Marvell and Toshiba and this enables their engineers to fine tune their final product that much more than we might see elsewhere.  Perhaps this is why Plextor has not experienced many of the same ‘hiccups’ that other manufacturers have.

Plextor M6S 256GB SSD Standing

The Plextor M6S SSD introduces the Marvell 88SS9188 eight channel controller which, for the most part, seems to be similar to that of the 88SS9189 that we recently looked at in the Micron M550 SSD.  Toshiba Toggle Mode memory has always been regarded as amongst the best in the business and strong performance of 521MB/s read, 448MB/s write with 88K IOPS resulted through our own testing.  These are strong results, however, we have to wonder if Plextor is holding the best performance for a future release of…say a M6P Xtreme Series???  In any event, we believe higher performance can be achieved to match that of the Crucial M550, albeit the M550 also relies on their own native Write Acceleration.

MSRP pricing comes in at above $1/GB for the 128GB capacity and just below for the 256 and 512GB sizes.  These are ‘suggested’ pricing models and we might think they will drop slightly, however, in today’s SSD market, price has become a key contributor to sales success and there are plenty that fall in well below the price of the Plextor M6S.  We might think that these prices will have to drop to ensure success of the Plextor M6S SATA 3 SSD.

FINAL THOUGHTS

If reputation and SSD reliability are top priorities in your SSD purchase, we would definitely recommend the Plextor M6S SSD for your PC.  Conversely, if you are value conscious, or are looking for the most space for your buck, you might watch pricing of the Plextor M6S SSD closely for a bit to see where it settles.

  1. Nice to see another player in the arena.

    BUT i can’t help to find them overpriced and somewhat slow.
    I appreciate their good name in reliability but that argument is steadily losing ground
    nowadays with even OCZ’s latest offerings being quite reliable.
    Samsung, Intel, crucial all are reliable and is just so many options.

    Plextor needs to realize that the days they bested sandforce in almost every aspect,
    are long gone and price their ssd’s accordingly.

  2. This time Plextor quite fails .. even on anandtech M6M and this has low performance .. ? and few months back it was one of the best ?
    I really dont understand your tests it is all bollocks

    • No man it’s not all “bollocks”…
      It’s just that every ssd is so fast now that you won’t pretty much feel the diffrence
      between this and 840/vector when your case cover closes.
      Reliability and Value are the top factors now and at least a silver budge is justified on this.
      Although as i said before Value begins to be THE factor now.
      And yes sometime before M5P Extreme was one of the best in all departments including performance, so why are you asking??

      • Well the way of reviewing ssds should be changed .. people gets confused missunderstood
        On that anandtech web they pretty much SLAGGING m6m ..
        Their tests are completelly useles wrong. Drives espec. Ssds shouldnt be tested this way ..
        Most important is real world use

      • I don’t understand you, why the tests are wrong?
        He uses all the best and most recognized tools for ssd benching.
        These tools are designed to show you diffs in performance that in real world usage are almost invisible.
        Like i told you real life use is the same in ssds in our days. To show a graph where office instals 0.3ns faster in one drive than another is pretty much useless.

      • Yes that i knew long time ago mate i have 10 different ssds
        What am trying to say these tests are too much in depth which is not how should be
        You lokking at miliseconds .seconds and that end user will NEVER register
        It is useles and then when ssds are compared is such depth the differences are revealed and as people are naive once they see such negativness in review it will pull them out to choose or buy that product ..
        For example read and write speeds will never go higher than 500MB SATA III is advertised as 600MB but treshold is somewhere btw. 500-550
        And about 4k some perform less some bit more but difference in reality is never registered when u behind pc .. Point.is the such in depth review of ssds is waste and driving people not buy it
        But in other way best ssd is the cheapest one .. and more people goes this way

      • Well, there are people that actually need every IOPS, so such reviews actually matter to tham. You don’t have to read the review, if you don’t like it.
        Also, testing real world ssd performance is quite hard (and possibly inconsistent), thats why nobody does it anymore.

      • Benjamin covered me but i’d like to add a question.
        What do you suggest is the best way to test them?
        Maybe with your logic we shouldn’t test them at all and just have a price catalog?
        Sorry man, you have some points but you can’t come in an enthusiast community and ask for less info on the products…

      • Well keep testing as it is but at the end of review show that reality is that difference btw ”best benchmarked” ssd is very small ..
        You know I had installed 6 brands SSDs and with Win experience index the score was always 8.1 or 8.2 means difference is minimal

      • I am a bit confused as you seem to state one point and then go to another by stating that the tests are too confusing…
        From our perspective… The question as to how we test is an ongoing topic and we have decided our means of testing over much conversation, just like this. If you look at our enterprise tests, they differ significantly from consumer testing.
        Having said that, real world testing is a nice add on but what is valuable to one is useless to another. Conversely, websites with their own ‘testing format’ still do the same as others that elect to use simple programs such as ATTO, AS SSD, Crystal, Anvil and PCMark. In the end, we test performance by transfer speeds with both compressible and incompressible data. You can color coat that any way you wish with your own fancy dancy testing software but regardless…the same result is accomplished.
        From our perspective, we want to test consumer SSDs at the consumer level and we want the typical consumer to understand. It is an added benefit that we test with software that you can test with because many use this software to compare and ensure their SSD is working properly. Not every reviewer will agree on every SSD but, let’s face it, this SSD has premium memory, a great processor, reputable DRAM cache and is a key entry for a specific crowd.
        In the end, if all reviewers had the same report and opinion of a drive, that would take away what is best about the independence of being a reputable review site. Let me list two very specific examples that we differed greatly from the rest of the world. The first was with the Samsung Series 9 where we identified SEVERE wifi problems well after so many said this was the new age in ultrabooks. The second was with respect to Seagate Momentus XT where we stated time and time again that no visible performance was observed…So many others thought this was the best thing since sliced bread.
        It brings me way back to when we were the first to post that page file should be shut down with SSDs as well as auto system backusp…. not everybody will ever agree but the independence of thought is paramount.

      • Well said Les.
        Keep up the good work!

      • Hi Les, I think that controller has only 4 channels and not 8 can you clarify that. I’m getting conflicting info.

      • You are correct. We never had the pdf available to us at that point in time and received different information obviously.

  3. So the idea is to give every single drive an award so that people buy it with your amazon links? This drive was universally “meh” on every other site, but i see every single drive here gets an award and an sponsored amazon link.

  4. Excellent review Les!

  5. Is the sequential transferrate equal from begin to the end? To much manufacturers cheating in that case (Samsung Evo, Toshiba Q-series)

    • Explain please… do you meanas file size progresses or through a times transfer?

      • The Evo and Q-series “cheat” because both use for a limited time a SLC-mode. The Evo can hold for some seconds about 500MB/s and then it drops to about 250MB/s (250GB-version). The Toshiba write 50% with over 450MB/s and then drops to <100MB/s because it wrote the 1st50% in SLC-mode and then it writes to second bit of the NAND

        Benchmarks like AS SSD, Crystal Disk Mark and Atto wrote to less GB to show this behaviour
