840 Pro Raid 0 VS Single 850 Pro

[Jacob_22]

I built a system a few years back and just for the hell of it put 3 Samsung 840 Pros in Raid 0. (Did not care about recovery or cost, pure gaming system). I recently got a good deal on a single 850 pro and bought it. Everything I have read seems to indicate the benefits of raid 0 in SSD are not that significant.

However, when I re-imaged my new 850 and ran a disk test using AIDA64 the results are pretty different. The Raid is getting about 3x MBs than what the 850 is getting.

Storage experts, what am I missing here? Again, I do not care about recovery. all my "important" stuff is synced off site.


I am really losing that much speed

Samsung SSDs don't like being in RAID configurations and I don't recommend it. RAID array performance over standard SSD performance is nominal at best. I'd stick with a single 850 Pro over the 840 Pro RAID configuration any day.


If you run an AS SSD benchmark or a full suite of benchmarks, you probably won't see similar results to those in your test. The fact that you were able to run those drives in RAID is notable, but is not representative of the results that most users have had. Samsung specifically indicates not using their SSDs in RAID configurations. Also, I'd be willing to bet that if you enabled RAPID on the single 850, you'll see much higher scores, especially on sequential processes.

Thanks Darkbreeze, you were absolutely right. Just for giggles I put the raid back in just to run AS and Samsung Magician tests. The results were way different than what I got before.

I kind of figured. Hopefully it was of some help. If you do a lot of sequential file transfers, with really big file sizes, enabling RAPID is worthwhile as it DOES significantly decrease file transfer times and also reads. If not, or if you have 8GB of RAM or less, I'd leave it disabled as RAPID does use memory to speed things up and can be quite a hog about it sometimes. Good luck.
