Samsung 840 EVO mSATA SSD Review – 1TB mSATA SSD Capacity Along With TurboWrite and Great Security Features


Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data.  AS SSD, for the most part, gives us the ‘worst case scenario’ in SSD transfer speeds because of its use of incompressible data and many enthusiasts like to AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

As well, the ISO and Game file transfer was very quick, although we would have liked to see transfer speeds of the Program higher.


You may not see this for long (and it’s definitely not common) but you get a freebee 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 use in our benchmark testing.

Once again, although transfer speeds were a bit lower than listed specifications, IOPS results were impressive as was the Total Score.


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 Samsung 840 EVO mSATA SSD provided very impressive results in Vantage testing with a high Total Score of 75212 and top transfer speed of 415MB/s while testing in Windows Media Center.  Equally impressive was the fact that we had 7 of 8 results reach SATA 3 speeds, two of which were above 400MB/s.  Checking our original review of the Samsung 840 EVO 1TB SSD notebook form factor, results between the two are very similar.

As we can see in our Vantage mSATA Hierarchy Chart, the Samsung 840 EVO mSATA SSD seems to be top dog with its impressive 75212 Total Score.  It merits stating that this chart only provides comparison of PCMark Vantage Total Point scores and may differ when comparing such things as compressible and incompressible transfer speeds, as well as IOPS.

Samsung Magician also provides a benchmark program which provides both transfer speed and IOPS performance of Samsung SSDs.  Although we might normally avoid benchmarks that were created by manufacturers, this result will be a good comparison once we start examining RAPID mode performance.

As we can see, both read and write throughput and IOPS are almost dead-on listed specifications.  One might think that final specs may have been derived from this benchmark program.

    Hard work at the end of the year . Thats one nice ssd it will give a lot more power to laptops as well as space, but the price is still too high. I like to see is 2-3 in NBs and no hdds!

      I don’t know… I can see this in the $500’s in a month or two from now…just as we see the notebook EVO at times.

        I think it will be 10-15% more expensive, but whatever that say it’s still a lots of money just for storage. For that much money , more people will buy ordinary PC/NB based on HDDs. Lets say $300 for 1TB is quite reasonable price, at least thats what i will be able to pay and not regret it !

        Happy New Year TSSDR in advance !

    I bought the Samsung ssd 1tb. The drive is awesome. The Magician software did not work for me. My ssd would only be seen as NON OS drive. I had to clone my hhd to ssd using third party software outside my OS. It now works. Samsung does not offer support for these types of issues.

      Sign up to our forums and we can walk you through this. Is your SSD recognized in the BIOS? You may have to initiate it in Win 7 before all else falls in place. I dont see it available yet; where did you get yours?

    When is this going to be released? When and where can I get my hands on a full TB of storage for my Ultrabook? Personally, I probably would feel that it was expensive if i cared about the price at all. I will pay for it and not bat an eye. I am sure that there are more of me out there, too. THanks for the great review. I AM SOLD

    K……Ive seen a ton of reviews for these new Msata 840 EVO drives now for well over a month…… when the f * * k are these things going to be released for sale? Was supposed to be end of last month, then last week, then this week.,……………..getting obnoxious……..

    Will these be available retail or OEM initiall? I plan to buy a new custom gaming laptop very soon.

    When is this available?

    Did notice trim not working correctly on the new evo mSata drive?

    When can we see 4TB SSD in 2.5″ form? Since 840 Evo mSATA has 4 NAND packages to make 1TB, so I guess they can easily make 4TB 2.5″ SSD using 16 NAND packages…..

    what happens to the files in the turbowrite buffer if a blue screen of death/system failure occurs? are any of you owners of an evo msata or 2.5″ drive and have had a system failure or bsod? if so, what happened to the files?

    Hi thank you for this great review! I am trying to put together a laptop and I got no idea about the difference between ssd and msata besides their size. Should I pick 840 evo msata ssd 500gb over 840 evo ssd 500gb? Are they any different besides the size?

      There is no difference with respect to performance. What I might do is to install the EVO mSATA in your laptop and use the original HDD solely as secondary storage. Don’t forget to use our links of shopping through Amazon…for any purchases!
