Samsung SSD 960 EVO NVMe M.2 Review: Ultra Fast, Affordable Storage
SANDRA and ATTO Disk Benchmark
Next we ran SiSoft SANDRA 2015 SP3, 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 partitions that filled the entire available capacity of the drives. Read and write performance metrics are detailed below.
The Samsung SSD 960 EVO put up the best number we've seen in the read portion of this benchmark, but offered middling performance in the write test.
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 Samsung SSD 960 EVO put up some strong numbers here. With small transfers, it hung with the fastest drives out there. As the transfer size increased, performance remains strong and falls in behind only the higher-end SSD 960 Pro.
