Samsung 950 Pro M.2 PCIe Gen 3x4 NVMe SSD RAID 0 Report

Final Thoughts




Throughout our testing, we saw compelling performance from both of our dual drive 950 Pro arrays. There really is no question in our minds; a bootable PCIe array makes for the ultimate operating system disk. Some of you will undoubtedly have concerns about the increased potential for data loss that RAID 0 introduces into the mix. To us, there is really not much of a reason for concern. SSDs have become extremely reliable and of all the arrays we've run over the years, exactly none have failed. We do encourage taking system images/backups on a regular basis which is a practice that we encourage for a standard OS disk as well.



We wish Intel would have built-in more bandwidth into DMI 3.0, but 3.4 GB/s read and 3.1 GB/s write is still pretty exciting. When you consider that this much storage bandwidth is available without encroaching on CPU lanes, DMI 3.0 is very attractive. We had no issues whatsoever in setting up our bootable PCIe arrays; it is something that any average user should be able to accomplish with minimal effort.


Samsung is targeting the 950 Pro at heavy workload professionals, which is an ideal use case scenario for this tiny, powerful SSD, but it is also ideal for enthusiasts especially in a RAID 0 configuration like we tested today. With all that affordable performance available without taking up any CPU lanes, gamers will rejoice.


As we progressed through our testing, we saw significant performance increases over a single drive. When working with mixed workloads, we saw sustained performance increases of up to double that of a single drive as evidenced by our sledgehammer test. The only contradictory benchmark we encountered was standard PCMark 8 testing where a single drive outperformed our two drive arrays. This result was rebuffed when we ran PCMark 8 Extended as well as by every other benchmark we ran.


We love the way our test system runs with a 950 Pro array. It is noticeably more responsive than a single 950 Pro and even boots faster. From our perspective, a 950 Pro array provided the best SSD experience we've ever had. RAID 0 is back, and we encourage you to give it a try. You won't be disappointed.
