AnandTech Storage Bench - Light

The Light trace is designed to be an accurate illustration of basic usage. It's basically a subset of the Heavy trace, but we've left out some workloads to reduce the writes and make it more read intensive in general. Please refer to this article for full details of the test.

Now the 250GB MX200 enjoys a small benefit over the larger capacities when the drive is empty as the SLC cache is in its most effective state (the Light trace writes so little that all can be written in SLC). However, once the drive is full, the 250GB again loses a substantial part of its performance drops below any other SSD we have tested. Overall the BX100 is a better fit for light workloads, although the difference isn't huge (10-15%).

Power consumption remains good and competitive against other high-end drives, except for the full 250GB model that draws a lot more power as it needs to write all data twice.

    I'm hoping that once other companies get 3D NAND into production we will see some interesting competition for Samsung. Reply

    I love how they post this but not the mx100 tests.... whats the FKING POINT in testing than? Reply

    I'm not sure I follow. The MX100 is in our graphs. Reply

    Question about the hardware encryption.

    Where does the key come from? Can I set my own key?

    The reason I ask is, if all the drives have the same key from the manufacturer then it is like there is no key at all. As if you know one key you know them all.

    If it is made by a random number generator, how do we not know there is a pattern from the generator so a hacker only needs to do a few thousand (million?) tests to break the encryption?

    If on the other-hand we can set the key, is it easy to do? Is the key such that we can write it to the drive but it is hard to read out?

    Wow I just purchased the MX200 250GB a couple of days ago.
    If I had read this article before, I wouldn't have bought it.
    btw, thanks for this great article, AT :)

    Lol, same for me here. Should have gotten a BX100. The MX200 performs without problems though, so no point returning it, just it's not the best value for money. Reply

    If you don't fill it in a sudden rush, it's still a fine drive. Not the best choice, but not terrible either. Reply

    The Samsung 850 pro 1tb is missing from most charts, disappointing. Reply

    No comments on the NAND being 16nm? Is this not an issue? I am reluctant to buy MX100, 200 and BX100 when there is M500 still in stock (the price seems to be rising).

    Another review request : Intel`s new SSD 535 (this seems to use hynix 16nm NAND memory).

    No, it's not an issue. Even with "just" the guaranteed endurance it's going to last a long time. And very probably a lot longer, as in any SSD which is not under continous sustained use (which would cause very high write amplification). Reply
