If the anomalies persisted, I would restart the computer, delete and re-create the raid and re-test everything with the same settings. In the case of anomalies in the data, the tests were run again. Finally, CrystalDiskMark was opened and the tests were run. After this, an NTFS partition was created with all default values using all of the unallocated space on the RAID.

I then booted into windows from a separate drive, and once booted, windows disk manager was opened where the RAID was initialized with a GUID Partition Table. To get the data, the RAIDs were created by restarting my computer and pressing ctrl+I when prompted to get into the Intel RAID configuration where I deleted the old RAID (if applicable) and created the new RAID 0 array with the drives and stripe size for the corresponding test. On top of these 3 RAID categories, I also took benchmarks of just a single M550, a single 850 EVO and a WD Black 1TB drive for reference (or for anyone looking for those numbers).

Lastly I wanted to test all 4 SSDs in one large RAID 0 array since this is what I will be running on my main pc in the long run (with frequent back ups, of course) and I really wanted to push the array to the bandwidth limits of the PCH and see what the intel RAID controller can do when given an abundance of competent hardware.

While the M550 and 850 EVO perform pretty similarly in most categories, they use completely different internals, all the way to the controller, so I was interested to see how they would pair together

Secondly I wanted to test a simple config where I mixed one of each drive to see how it performs.

As for the categories, I wanted to test simple 2xM550 RAIDs as well as 2x850 EVO RAIDs so I can get some numbers and put them up here so other people looking to do this simple config can know a ballpark of exactly what they may be getting.

So I wanted to test a few things, firstly, I wanted to test the performance of RAID 0 with different stripe sizes, so every RAID has been tested in all of the stripe sizes available on the intel RAID controller (4kb, 8kb, 16kb, 32kb, 64kb, and 128kb). You should also know that I used CrystalDiskMark 3.0.3 圆4 for all of my tests and recorded every value I got into a spreadsheet. I decided this was a great opportunity to look at different RAID 0 configurations with SSDs since I had so many, so I did and recorded all my results!įirst off, I guess I should say that I'm using the integrated intel RAID controller on a Z97 chipset motherboard. I initially bought 2 Crucial M550 256GB drives, and then proceeded to buy 2 Samsung 850 EVO 250GB drives a few months later when they were released.

Measured with both BlackMagic Disk speed test and iStatus menus.So, for my personal rig, I decided to go a little overboard with the storage solution.

Without RAID, the same happens, I get around 500MB/s read speed but only 100MB/s write speeds.Īfter trying with all available chunk sizes (from 32k to 256k) for the RAID, still getting the same results. Read speeds are as expected, around 750MB/s. The problem is that I'm getting write speeds of around 100MB/s on the data RAID when I should be getting around 800MB/s.

(I already tried with OWC RAID software with same results) I installed them using NewerTech adaptors and formatted them in RAID 0 using Disk Utility RAID assistant. Recently I bought two 1TB Samsung EVO 860 SSD to improve performance of my data drives. I'm using a ThunderBay 4 external enclosure as my main storage and backup unit.
