No one hardware raidcontrollers support raid yet. Areca said they are working on it. They said it 4 years ago...

Adaptec 31605 is VERY slow for ssd's. High latency and not good enough bandwidth.

I doubt it too. If they would it would definitely be mentioned here:

Agree, bit slow but adequate for storage space. And I only got it for £20 off a man who didn't really know what it was smile.gif cost me more for the cables lol

Is it possible to put 830 and 850 in raid0? Would the RAPID work then?

Im also wondering how much raid0 could benefit in game load times? Example with Dayz standalone, Arma3, BF4, GTA V (well its not available yet but its going to be huge game)?

You can, but RAPID......meh.... You won't be able to use RAPID and you shouldn't really.....

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 SSDs

I remember having to use processidletasks call now and again to flush the ram and really save the stuff to my drives. I turn this feature off by going to the drive properties, then turning off the caches from there, its a pain when your told to "save your work" and the computer don't, find out after a your miss's unplugs you to plug a hoover in... Ive learnt my lesson smile.gif

Well I'm just trying RAPID because of I can wink.gif I want to expericen it myself, Not because of benchmarks.
I don't see myself oftein copying over +10GB large files to other drives. But I tried your test with 25,5GB video file and didn't see any corruption in video or audio. It wasn't insanely fast, only 200MB/s. I copied it there almost 100MB/s from WD green, thats only twice as fast.

I have just install an SSD 840 EVO msata on my Laptop, I am not sure with it temperature, normal operation temperature is 57 Celsius and benchmark with CrystalDiskMark it up to 82 Celsius mad.gif.

I read info from http://www.samsung.com/global/business/semiconductor/minisite/SSD/global/html/ssd840evo/specifications.html normal degree from 0 to 70 (C).

I use many software like AIDA64, Crystal Info, HD Tune Pro, SpeedFan it show the same. I post here the raw SMART data so anyone can help me make it clear.
Samsung store raw value in Dec not Hex? But the total in raw and current is 100, i think it Celsius.






Edit: Update 82 degree Celsius image

I brought Samsung 850 evo 250GB, and i got these speeds







It's should be 540/520 as advertised, and 4K speed are very low.

i tried a lot tweaks, tutorials, disabled power savings of cpu in bios. Is there anything else i
can do or face that amd sata driver i just slow, or nor good enought? This platform is slow for maxing out ssd speeds?


Samsung magician says everything is connected well..

My pc

win 8.1 pro
fx6300 4100mhz
4gb 1866
