    How to enable Rapid mode on Samsun 850 Pro


    Quick steps:
    1. Remove any versions of Samsung Magician later than 4.5 (inclusive)
    2. Download an d install Samsung Magician 4.4
    3. Start it, enable Rapid Mode, and reboot
    4. (If desired - I did this) remove Samsung Magician from Startup group

    Longer explanation:

    Originally I did a clean install of Build 10240 on a brand new 850 Pro. The disk that came with the drive was Magician 4.5, so I pitched that and downloaded and installed Magician 4.6. After seeing that it did not allow enabling Rapid Mode I started doing some research and found several posts that said Magician 4.4 did run on Win10 and did support rapid mode.

    So I used Uninstaller Pro (which I use to uninstall everything) to uninstall Magician 4.6, found a place to download Magician 4.4, installed it, and rebooted. Here is my first screenshot showing my 850 Pro:

    You can see the 850 Pro is recognized A-OK, but rapid mode was not enabled. To see what difference it might make I ran the internal benchmark:

    This is the benchmark results before enabling Rapid mode. After that I enabled Rapid mode, rebooted, and ran the same benchmark again. Here are those results:

    It's pretty clear Rapid mode is a good thing to do and Magician 4.4 allows it to work.

    @bbinnard,

    How stable is it running for you now? I had BSODs during the Preview running RAPID. Actually Magician would crash a lot first(on an older version) and after a few times NUKE the4 system, so I got the latest version(4.6) and kept RAPID off. Also if it is running stable please give a link to SM 4.4.

    Rapid mode is just an aggressive filesystem cache right?

    So it really only accelerates reads the second time you open a file, and makes buffer flush times longer and more dangerous on systems without a battery backup.

    Cliff - it's only been several hours, but I have rebooted a few times and run different things. No problems at all.

    I lost the link to 4.4, but just google "samsung magician 4.4 download" an you'll find several places. I got it from one of those software distribution sites.

    Hydranix - my system is connected to a UPS. Isn't everyone's?

    Sounds good, maybe my earlier problems were because the preview didn't have all the permissions that the finished product does.

    Good counter, and a UPS is a good investment

    Thanks again for the update
