Intel 750 NVMe 400GB U.2 SSD Bootable RAID 0 Report

CrystalDiskMark

 

Version and / or Patch Used: 3.0 Technical Preview

 

CrystalDiskMark is disk benchmark software that allows us to benchmark 4k and 4k queue depths with accuracy. Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at QD4.

Our 750 array has the advantage over a single drive in only one area of this test; sequential performance. In contrast to what we saw with ATTO, the 950 Pro arrays deliver better sequential performance than the 750 array because this version of CMD measures sequential performance at QD1, we use QD4 with ATTO.

Write performance is where an array has a significant advantage over a single drive. In this case, the chipset isn't getting in the way of maximum performance. Our dual 400GB 750 array is delivering 100% better sequential performance, and more importantly, 30% better 4K QD1 random performance than a single drive. The performance of our 750 array is almost identical to our dual 256GB 950 Pro array.

 

 

AS SSD

 

Version and / or Patch Used: 1.7.4739.38088

 

AS SSD determines the performance of Solid-State Drives (SSD). The tool contains four synthetic as well as three practice tests. The synthetic tests are to determine the sequential and random read and write performance of the SSD.

So much of AS SSD's scoring comes from 4K-64 thread performance, which is nearly irrelevant in a consumer setting, that scoring may not reflect what can be expected in terms of real-world performance. We still use AS SSD because it's a very popular test that many enthusiasts use and scoring aside, it does provide important data. Our 750 array delivers the best score.

 

With our synthetic testing out of the way, let's take a look at our moderate workload testing.
