Samsung 840 Series 250GB SSD Review – The Worlds First TLC SSD Takes Center Stage

TEST BENCH AND PROTOCOL

Our analysis today will be conducted with our Asus Z77 Premium Test Bench.

In testing, our main objective is to obtain results as pure and as accurate as possible and we want to ensure that no anomalies slip through. Simply put, we want to provide you with the absolute best results the tested hardware can provide. Repetition in testing is standard and, if necessary, we may conduct specific tests in Windows 7 safe mode to ensure the OS has little to no influence on the end result.

In order to validate and confirm our findings, testing is supported by industry accepted benchmark programs. All results are displayed through capture of the actual benchmark for better understanding of the testing process by the reader.

We would like to thank ASUS (P8Z77-V Premium), Intel (Core i7-3770K), Crucial (Ballistix), Corsair (H100) and Be Quiet (PSU/Fans) for supporting the build of our Z77 Premium Test Bench.

BENCHMARK SOFTWARE

The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal DiskMark, AS SSD, Anvil Storage Utilities and PCMark Vantage.  We rely on these as they each have a way of supporting one another yet, at the same time, adding a new performance benchmark to the total picture.  Much of the software is free and can be downloaded simply by clicking on the linked title.

SAMSUNGS NEW CONTROLLER

The new Samsung controller is a 3 core MDX device that operates on eight channels and has a model number of S4LNO21X01-8030. Here we have a bit of a close up view of the controller first hand:

CRYSTAL DISK INFO VER 3.9.3

Crystal Disk Info provides some excellent information about the SSD itself to include its health, product information, ‘power on’ information as well as the characteristics of the SSD. We can see that the SSD is capable of TRIM as it is not greyed out as with APM and AAM.

  1. I especially like the image of the SSD standing on end among office buildings.

  2. On page 8 , slight mistake in the title and the chart, we are testing the Samsung 840, not the 830. Awesome review though.

    • Thanks and that is actually an editorial trick! Now, we are certain that we have at least one reader and the article was a success. Fixed!

      • Really liked the review I also have a 128gb 840 pro and a 128gb 830 Samsung drives bought the 840 250gb set as my OS(windows 8) drive to see how it runs so far really impressed in real world use very similar to my 128gb 840pro better than the to crucial M4 128gb and 64gb I decided on smaller drives and I rotate them every few months. They all get a turn at running the OS spreads the writes around all the drives.
        Samsung has good track record with SSDs so figured it was worth a try

  3. WOW that is one nice SSD. SSDs are really starting to improve at an amazing rate.

  4. Any thoughts of setting up an 8-drive RAID test on a nice LSI adapter???? I’d love to see how the Pro numbers scale up.

  5. need the 840 Pro version for 256gb.. not really that interested in TLC drives. just how many P/E cycles are these drives? the TLC and Pro version?

  6. TLC? Not for me! I wish companies had stuck with SLC because by now it would be cheap! I am considering an 840 PRO 512GB.

  7. I was hoping the Pro version would be pure SLC.

  8. i think you still dont get the whole notebook reason to test with one.
    also if your going to use a high end desktop atleast do a raid test.
    also a FDE test would be a huge help.
    it really sad how poorly most site do on testing and reviews.
    i do like this site but it allmost like most tech people cant wait to toss any review into there intercooled overclocked jet fueled desktop.
    not exactly real world is it.
    most people who buy a ssd are putting it in a laptop/notebook where this is the only upgrade they get.
    most worry about power use/heat and how secure it will be.
    so testing on a notebook is important and data protection.
    great work buy the way and you were 100% right on with samsung way back.
    you should also review that apple 2012 ssd that listed on the top of passmarks site.

    • I have tested the 2012 Apple SSD earlier and your pointys are well taken. Pros and Cons with respect to doing the actualy testing in a laptop and the definite cons are the fact that there are so many laptops that vary in hardware and setup. By testing on our main bench, we can achieve ideal performance at ideal conditions which we thnk is a valid trade off.

      As for the notebook, you are absolutely right when speaking of performance which could never be measured, in the way of battery life, on a desktop system. We are looking into being able to verify specified power ratings which might be a happy medium. As far as RAID testing…. we are hoping to get several drives in the near future…

  9. as for all the life talk it silly if you ask me.
    ssd change so fast we are on what gen now.
    i retired two of my asax leopard hunt drives from desktop duty to ps3 duty.
    my point here is we end up buying new tech every 2-3 years or less for some of us and just sell off what we can.
    talking of 10 year life spans is really silly unless it enterprize market and there i am certin size and price along with speed and power use are a huge factor for them when thinking of use.
    i have tested and used many ssd and never seen one fail and that leopard hunt got the bag beat out it with many os changes,betas,hardware,benchs and it not failed.
    i think enviroment would be the one thing i would worry about.
    silicon chips do not like mosture like humid places.
    i dont see any one talking how there old server pc in the basement would not boot up after they were away for a month.
    it be nice if they sealed them and put a mini usb port on them and not charge a extra 50 to 100 bucks.

  10. Innovation bring progress, Samsung is maybe one of the 1st that try their own controller, now their first TLC SSD, i think they are looking into the future not just for customers money!

  11. hi there yeah my bacbook air has more flash storage it has a 256 gb ssd so i get 6 gb more copacity and bigger then a 250 gb drive

  12. Quick question.. can by just dropping this SSD on a wood floor render it inoperable? I have someone from whom I Am to purchase one of these and now wants to renig by saying it was dropped and no longer works. Is this a dupe because I think he realizes that the price was wrong.. TIA bo1953

  13. I am assuming that on page 3 “System Information provides a good luck at your system hardware”, luck should really read look..
    But luck would be welcome too ..

  14. i could not disagree more. the 840 price is WAY to high. right now
    the 840 sells at the same price as the 830 which is a better drive. how
    can making a TLC drive that performs worse then your last generation MLC
    drive for the same price be a positive? now if they want to sell the
    840 250GB for under $150 then im interested. as of now im either buying
    the 840 pro or the 830. why would anyone buy a 840 until the 830 stock
    is gone?

  15. I can’t decide. This or the 240Gb SanDisk Extreme for the same price?

  16. i have “external exception E06D7363” error when trying to clone window 8! how do you fix that? other data migration software?
