Samsung SSD 970 EVO Plus 2TB Review: Burly, Speedy NVMe Storage

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.

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.

The 2TB Samsung SSD 970 EVO Plus drives performed very well for most in the ATTO transfer tests, but read and write performance tapered off once it hit the 4MB transfer size.
