Next we used SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant for some quick tests. Here, we used the Physical Disk test suite and provide the results from our comparison SSDs. The benchmarks were run on clean drives that lacked any partitions. Read and write performance metrics are detailed below.

SiSoft SANDRA

Synthetic Disk Benchmarking

The WD Black SN750 offers the second best write performance of the bunch, trailing only the more-expensive Samsung SSD 970 EVO Plus. The drive's read performance -- while good at almost 2.9GB/s -- ends up trailing most of the drives but a couple of percentage points.

ATTO Disk Benchmark

More Information Here: http://bit.ly/btuV6w

ATTO is another "quick and dirty" type of disk benchmark that measures transfer speeds across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5KB through 64MB transfer sizes and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than I/O response time, access latency, etc.

Once it is able to stretch its wings, at transfer sizes above 128K mark, the WD Black SN750 competes well with the top-end drives in both the read and write tests here. It end up near the top, and trails only the Samsung SSD 970 EVO Plus.
