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.

The Tempo outperforms both Intel 750's in three of the five measured categories. It delivers better sequential, 4K QD1 and 4K QD4 performance, which indicates that the Tempo will deliver better moderate workload performance than Intel's 750 series. Overall, Samsung's 950 Pro takes the win for the read portion of this testing.

The Tempo outperforms the 950 Pro in four of the five measured categories. The NVMe-powered 950 Pro beats the Tempo at 4K QD1. Intel's 1.2TB 750 is lacking in sequential write speed but makes up for it with superior random performance.

 

 

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.

Intel's 750 SSDs dominate this testing due to the drive's superior random read/write performance. This is somewhat deceiving because the majority of the 750 Series' scoring comes from random performance at queue depths that are much higher than the average user will ever attain. All of the NVMe-powered drives outscore the Tempo.
