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.

With this version of CDM, Sequential performance is measured at QD1 which is the reason sequential rates are lower than Samsung's quoted numbers. This version of CDM measures performance at 512K transfers, so let's focus on that for a moment. The SM961 is only able to muster 507.4 MB/s with 512K read transfers. This is far below that of the rest of the drives in our test pool. The reason? Windows 10 NVMe driver vs. a proprietary NVMe driver.

The Windows in-box NVMe driver tends to deliver slightly better sequential performance, but other than that, it falls woefully short in most other and more important performance metrics. The 960 Pro wins this test hands down.

This is a new lab record for sequential write performance on this version of CDM. Keep in mind that we are running the 960 Pro as our OS Disk and it is 75% full, which can have a negative impact on performance depending on which benchmark we are running. The 960 Pro is in a class of its own.

AS SSD

Version and / or Patch Used: 1.7.4739.38088

AS SSD determines the performance of SSDs. 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.

AS SSD is a demanding test, and the 960 Pro sets yet another lab record. This is one of those tests that is greatly impacted in a negative way when data is on the disk as you will see when we get to our MOP testing which is run without data on the disk. We like to show many of our results with data on the disk and the disk running our OS, because this reflects what a user can expect to achieve if their system is well tuned.
