Samsung SSD 950 PRO M.2 Review: Affordable, Ultra Fast Storage
SANDRA and ATTO Disk Benchmarks
Next we ran SiSoft SANDRA 2014, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the File System test suite and provide the results from our comparison SSDs. The benchmarks were run on fully formatted drives, with software RAID 0 configured on the DC P3608. Read and write performance metrics are detailed below.

The Samsung SSD 950 PRO M.2 performed right about on par with the Intel SSD 750 series drive in the read portion of this benchmark, minus a few MB/s, but the Samsung drive put up better write scores here.

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 ATTO Disk Benchmark shows one of the Samsung SSD 950 PRO M.2's strengths. Although the Samsung drive put up slightly lower peak bandwidth scores, the SSD 950 PRO M.2 offered significantly better read throughput with transfer sizes below 256K.
