    Ok Dino, I tried 4.6 on build 74, it doesn't crash, but I doesn't let me use RAPID(it looks for Windows 7 and above but doesn't see 10, I guess it looks for version 6.xxx and Ten is 10.xxx like some other software too) so my first post still stands. Samsung needs to fix it. But thanks any way, I'll leave it in for now while testing. but if they don't fix it I may stay with 8.1 on my desktop and just put 10 on my laptop so the can sync. The laptop is my test machine for software & OS's, being I prefer a "real system" plus I have another drive for it as backup.
    There's a workaround for the 840--won't work on the 850 (Grrrrr-r-r-r-r 850 is what I have.) Uninstall Magician 4.6; install Magician 4.4 (do *not* let it upgrade to 4.5 as it will want to do)--it will recognize your 840 and will allow you to activate Rapid Mode under Win10. Once you activate it, then install 4.6 right over the top of 4.4--and Rapid Mode will stay on. However, if you turn it off under 4.6 you will have to rinse and repeat to enable it once again... Hope this helps. It won't work for the 850 because 4.4 doesn't recognize the 850..! So 4.6 doesn't recognize Win10 and 4.4 doesn't recognize the 850. Can't win for losing.

    Yes, that's what I said in the previous post. With 4.6, it'll allow you to update the firmware but Rapid was grayed out.

    I had RAPID on 4.5 but it causes BSOD's in windows 10, but thanks, I had thought maybe they fixed it...not.

    I hoping they fix it for windows 10, if not oh well to be able to update firmware is ok too.

    Well, that's a very good thing to know...! That even with the workaround for an 840...it still doesn't work in Win10 (10074 I assume is your build.) I can now end my quest to figure out how to get everything installed from the "RAPID" folder in the Magician directory (programs(x86))--I even created a tiny Win8.1 installation on another bootable drive so that I could see what Samsung was loading when it enabled rapid mode. There's a lot more to it than just the service...irony is that I'm pretty sure I got all of the drivers installed properly in Windows/system32/drivers & driverstore--but I cannot get Samsungrapidsvc.exe to run no matter what I do, even manually putting the program in the startup directory and booting doesn't work as it fails shortly after running--I can also get the "Samsung Rapid mode notification utility" to run at Win10 boot--it stays up--but when I run Magician 4.6 it shows rapid mode is enabled, but it also says "rapid mode is missing a component it needs to run, uninstall and then reinstall rapid mode to fix it." LOL... Didn't identify the missing component, but my guess is it's the service that I can't get to run in 10074--must be incompatible with either this build or else Win10 entirely. My problem is that I keep forgetting that everything doesn't have a workaround "if only I can find it"...

    So that's as close as I came to getting it to run under Win10 10074...Magician 4.6 says it's "enabled" but lacking something...but it definitely isn't enabled at all... I'm throwing in the towel on this one....Samsung needs to step up to the plate, here...

    I had it running in 9926 when I upgraded from Win7, but magician would crash. I then tried to install version 4.5 after clean install and got BSODs. Version 4.6 installs without crashing, but it's missing RAPID & Optimize. Version 4.6 even has optimize turned off in Win8.1(which is for TRIM and was actually put there for Windows versions without trim support). I just hope that they fix RAPID so it can "see" Windows version# 10.xxx.xxx and stop looking for just 6.xxx.xxx, because RAPID is a real boost. I have compared it to some PCIe SSD stats, and my Samsung 840 Pro blows them away(only with RAPID turned on).

    I have a brand new Samsung 850 Evo ( for $89? yes please!) sitting on the desk next to me waiting for Samsung to update the Magician software to recognize rapid mode in Win10 on the drive. Since the 850 Evo is not recognized by the 4.4 version, I cannot sneak up on rapid mode. I have to stick with my 840 Pro until then.
    BTW, rapid mode takes a while to tune itself to your most used programs and it works very well after it does. I remember after a few weeks, I booted up and said to myself "dang, that was fast!" and then remembered that I had started up rapid mode a while back. So it is a noticeable improvement.

    Rapid mode is not really all that important. You can use your 850 now, and it will perform great, and when the new magician software recognizes Windows 10, you just enable it for that extra boost.

    Here's what my stats look like.

    In real world performance (daily usage) Rapid Mode has little to no performance gains except for write speeds which don't really matter since on SSD's you're trying to limit as much writes to the drive as possible.

    Source: A closer look at RAPID DRAM caching on the Samsung 840 EVO SSD - The Tech Report - Page 1

    Unless you have like 16GB+ of memory installed and don't know what to do with the spare memory (RamDisk), I'd say enable Rapid Mode with 4GB cache since the newer version of Magician 4.6 allows for up to 4GB.

    Otherwise wait for an upgrade to next gen SATA express to to see real performance gains and not through some fancy caching via software only good for benchmarks.

    Edit:

    I'm really surprised Windows 10 doesn't have native SSD caching which would greatly speed up Windows for users who are on tight budget and want the best of both worlds (SSD's boot time/load time and storage space).

    Nemix thanks for the report link.

    EDIT: And thanks for posting in this thread, because, it reminded me I'll need to turn RAPID off anyhow, because Windows 10 will crash and burn if I leave it on, when it installs.

    Windows has had, for a very long time, something called SuperFetch, which isn't specifically for SSD's, but speeds up all kinds of disks. In fact, Samsung says Rapid mode is similar to SuperFetch, but provides a more "finely tuned" result and allows for greater ram utilization.
