AnandTech Storage Bench - Heavy

While The Destroyer focuses on sustained and worst-case performance by hammering the drive with nearly 1TB worth of writes, the Heavy trace provides a more typical enthusiast and power user workload. By writing less to the drive, the Heavy trace doesn't drive the SSD into steady-state and thus the trace gives us a good idea of peak performance combined with some basic garbage collection routines. For full details of the test, please refer to the this article.

AnandTech Storage Bench - Heavy (Data Rate)

In our Heavy trace the MX200 is an average drive: it's not as fast as Samsung drives, but roughly on par with the BX100. The most notable data point is the 250GB MX200 in full state because the drop in performance is tremendous, which is due to Dynamic Write Acceleration that is only enabled on the 250GB model. Because DWA writes everything to the SLC cache first, the drive constantly needs to migrate data from SLC to MLC, adding a significant amount of overhead and reducing the performance of host IOs.

The latencies are also good, except for the full 250GB MX200.

Power consumption under load is decent, but not BX100 level. The advantage over Samsung drives is notable, though, so the MX200 appears to be a pretty good fit for a laptop.

    Thanks for the honest review. Its a shame the MX200 doesn't excel like its brethren. Reply

    Agreed. That's why I appreciate seeing independent tests of manufacturers' claims. Crucial/Micron just showed me why I'll still buy Samsung over their drives. It's a shame; I used to recommend the MX100 as the best value drive. Now it's the 850 EVO all the way for value drives. Reply

    I feel the BX100 at the very least deserves consideration. The 850 Evo is not a blanket recommendation, especially for laptops where power consumption is important. The BX100 is probably the best mix of price / performance / power right now. Reply

    Then what you really want to look at is energy use for a given IO task. Consider the 512GB EVO and BX:
    EVO: ~350MB/s @ 1.6W. = 218.75 MB/J =
    BX100: 300MB/s @ 1.4W = 200 MB/J

    For a given task the EVO will finish faster and do it with less total energy use.

    but overall BX100 uses less power (i norm aim to buy BX100 for laptops unless SED drive is required then its norm intel 1000 or 2000 drive) Reply

    Considering the price of the M500's (960GB model <$300) I still use those almost exclusively unless the MX\BX100's happen to be cheaper. Been very happy with Crucial drives since the C300, very few issues and decent performance for the price. Support is now excellent with their "storage executive" software making firmware updates relatively painless. Reply

    Given the fact that most workloads won't cause noticable differences between high end and low end drives, the price, and the power loss protection mean that the ancient m500 is probably a better choice both featurewise and pricewise than its newer, faster competitors for most PCs. Reply

    Don't like the idea of DWA drives twice the amount of writes and silly more power draw (the bx100 is a good way on power just lacks FDE witch is unfortunate) mx200 is not on my list of drives to get Reply

    i am not sure why crucial stopped producing m550, it performs better than mx100 and mx200 series, and was true successor to the legendary m4 drive Reply

    Are the flash chips and controller it uses still available? If either has been discontinued they wouldn't have a choice. Even if the flash was available, but just significantly more expensive; keeping a competitive price would likely force their hand. Reply
