    Definitely looks promising on quick analysis and paper, but long term info needs to be available before I make purchases of Samsung drives now. We still don't know if the 840 EVO "fix" actually fixed anything as we still need to wait for that data to get old - sure it moved data around to "fix" it at the moment but the issue requires time to manifest. Now that they switched to different nand here it makes me think they didn't actually fix my 840 Evos. I'll do a wait and see on future Samsung products.

    Nice review. I do have a question. The 1 TB EVO and PRO both use the same MEX controller, have the same performance and both are priced around the same, give or take a few $. What would be the selling point for choosing one over the other? Someone who is not really familiar with SSD performance may be confused when really the only difference between the 2 is the casing. UNless I am missing something.

    where did you check prices? in my country 850 EVO 1TB is 441.67€ and 850 Pro 1TB is 570.55€. difference is pretty significant.

    btw, will we see other models reviewed, in particular 1TB one?

    Changing what I wrote, realised it was I that made the mistake!

    Since looks great, I've been looking for a replacement for my SSD.

    You mean Endurance?, that's correct. 75 and 150 TB written.

    The NAND flash serial # is different, long term it might behave different / an effect on endurance. However I doubt it, the numbers are so good. Samsung does not disclose the NAND differences (if any).

    Next to that only warranty is different e.g. 5 vs 10 years.

    Yes my mistake! I was thinking of it like GB and TB. Looks like a great drive!

    Not a single Crucial drive in the tests? The MX100s are extremely popular (have one myself), seems odd to leave out such a large brand.

    Crucial categorically refuses to send review samples to us. Believe me we tried.

    OK so they want 270 for a 500GB 850 evo or i can get an 850 pro for 320. 50 dollars isn't a big enough price difference for me to not just go with the pro edition. I've never been a fan of TLC. I feel like TLC adds extra complexity and more points of failure. I'll be sticking with the 850 pro until sata express drives finally come out.

    Well that is odd. I've certainly seen reviews in other sites. Why exclude this one?

    Just in time, my 240 GB Corsair GS SSD main drive is now 83% full and I could use an 500 GB drive now, and $252.00 with free shipping at New Egg is cheap.

    They may have bought them.

    I'm put off Samsung SSD's from the performance issues with the 840. I'll be sticking with the Corsair Force series.

    What I find funny is you will gladly use a sandforce ssd when sandforce had problems 10 times worse than samsung. Your logic is flawed bruh. Samsung and Intel make the most reliable ssd's but your loss. Samsung fixed the minor software issue in what a month after it was revealed or something. They took responsibility stepped up to the plate and fixed it. Cant ask for more from a company.

    I just want to correct some misinformation from your review. At least to my knowledge...

    SLC = Single-Level cell (1 bit per cell)
    MLC = Multi-Level cell (2 or more, usually 2)
    TLC = Triple-Level cell (3-bit MLC)

    Toggle NAND is something else, which could be compared to ONFI NAND.

    3D-/V-NAND means stacking cells vertically.

    You say the MGX controller uses a triple-core ARM processor, while Samsung states that it is dual-core.

    Thanks this was already corrected, yes the MGX is a lower power 2-core design whereas the MEX controller has a 3 core design.

    Nice review. It is the ssd I was planning to get for new gaming pc.

    Btw, does any one know what storage controller "MSI X99S SLI Plus" motherboard is using?

    All SATA connectors are derived from the native Intel X99 Express chipset.
