Samsung SSD 970 EVO & PRO: SANDRA And ATTO Benchmarks

Next we ran SiSoft SANDRA 2017, the the System ANalyzer, Diagnostic and Reporting Assistant. 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 partions. Read and write performance metrics are detailed below.

Synthetic Disk Benchmarking

The Samsung SSD 970 Pro and 970 EVO led the pack here in reads, though the WD Black NVMe continues to put up some impressive write scores.


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.

We've got a mish-mash of data to digest here. The WD Black NVMe once again puts up strong writes with the larger transfer sizes, but trails the other drives in both reads and writes with smaller transfers. the Samsung SSD 970 Pro and 970 EVO edge out the previous-gen 960 Pro in the write test as you would expect, and lead the other drives. In the read test, the 960 Pro is able to pull ahead of the 970 EVO, but the 970 Pro finishes at the top of the heap.
