So here is my final setup with 2 Samsung 850 PROs 1TB + 840 EVO mSATA 1TB benchmark results. I used a 16KB Stripe Size for the array as I don't deal with large files so that gives me the best OS / Programs snapiness.

Some impressive scores out there, congrats) How did you manage to RAID those 3 drives, 840 EVO is different to 850 pro! Is this a samsung thing or you can actually RAID drives that are not the same?

in RAID 0 yes,
Usually it's not good to mix diff. SSDs because if one of the other SSDs has a lower performance than the others, it would bring the overall performance down. But with the case of my 840 EVO mSATA 1TB, it actually has decent performance on par with the 850 PRO 1TB so it was a perfect mix -
Have you run into 840 EVO slowdown issues yet?
How do you plan to fix it if it shows up?
Those are nice speeds, add couple more drives and your RAM will be the bottleneck, just kidding.Phase and Spartan@HIDevolution like this. -

The reason I'm asking, I have 840 evo 256GB and many members here advised me to return it. But I think I can deal with it, by using diskfresh, restoring from backup, or even defragmenting it, in case slow down happens, I don't know if having this drive in RAID would make fix more complicated, but I'm glad it works well for you.

Would I recommend anyone to buy it? NO. Would I recommend anyone to buy anything from Samsung? HELL NO. My next set of SSD will all be SanDisk FTW I just hope they come up with mSATA stuff so I can maximize my storage capacity.TomJGX likes this. -
I read somewhere, that some SanDisk based SSD often BSOD, my SanDisk based pretty new Kingston SSD had massive amounts of errors, (I'm missing 12 GB of space), but it could be USB3 enclosure issue, not sure yet and I'm past return window on Samsung anyway, if I return it now, I'll probably get refurb and there is nothing wrong with it yet anyway.

SanDisk is tops in heavy workloads. They have performance consistency nailed for two generations now.
Check out TweakTown's RAID0 reports. http://www.tweaktown.com/cat/storage/raid/index.html RAID has it's drawbacks, as you can read here, performance isn't one of them. RAID0 also has different top performers. Intel 730 480GB is tops. 1TB SE Pro as SanDisk does very well in RAID0. Samsung is not strong in RAID0 -
Heres my 840 evo with rapid mode enabled,,SATA 3 6GB/s is present, crystaldisk needs an update

I dont think Samsung has enabled rapid mode for raid yet. You have impressive QD=32 results.
And Yes I never experienced a slowdown and yes Samsung has the Fastest SSD's.

If you turn on CRAPID mode, you are not benchmarking your SSD anymore, you are benchmarking your RAM.
Translate that intro real world performance and it means absolutely nothing.
For example, test this.....
Copy a huge 10GB + video file or whatever large file you want from your C: partition to another partition on another disk......
you will notice that the Windows file copy progress finishes insanely fast.....the moment it finishes the copy, I want you to restart your system
then check that file you copied, it would be corrupt, reason is, yes the file copy progress finished fast, but it didn't finish really, all it was doing is copying the file from your SSD to the RAM Cache and not the actual 2nd SSD or HDD you were intending to copy to, then after it goes to your RAM Cache using CRAPID, it is supposed to copy from the RAM Cache onto the actual disk in the background which didn't happen in this test I did since I restart immediately after the fake file transfer progress was finished.
so it's just cheating + placebo effect
And after you read this, you will never enable RAPID again.....it will actually make your performance worse not better
A Closer look at the crappy CRAPID
PS: I never enable RAPID on any of my 3 Samsung SSDsVasudev, TomJGX and tilleroftheearth like this. -

lol damn next time I'll just shut up about my subjective experience lest I get quoted everywhere
Yes the Extreme Pro does feel snappier, but it's very much a subjective thing, and LunaP who also owns both tells me she can't tell the difference whether in everyday use or heavy workloads. So YMMV, and again I emphasize the "subjective" part.Bullrun likes this. -
I knew you had experience with both. Pointing to real user experience is useful, if it's available. Especially, if the user has accepted knowledge in the subject. Good to know about LunaP's experience too. I hadn't seen it before. I'll emphasize "subjective" if I answer this question again.... You know it keeps coming up.

Another thing that turned me off is every single benchmark I've seen shows the 850 PRO is faster than the SanDisk Extreme PRO so that made me hesitate -
Not an empty drive benchmark, I go here first, every time. Steady state testing. This isn't the whole story, of course. It seems to be the closest to "real world" performance at this time.
http://www.tweaktown.com/reviews/7016/ocz-vector-180-960gb-ssd-review/index7.html
Hopefully, some steady state mixed read/writes in an OS environment is coming soon. A few sites have added some mixed workloads but they seem to be sequential only. -

OK. Here's the old style with numbers (which I prefer too). Note: The blue bar is high performance (heavy usage)

My decision would be based on MY workflow (heavier usage than the average consumer) so I look to the high performance in steady state. The laptop I'm on now, light usage, has an Intel 335, good enough for this purpose. If I was buying for this machine today, I would be looking at a Crucial MX100. Low price and good in light to very light usage. -
