Samsung SSD 860 Pro Review: Fast, Reliable SATA Solid State Storage

Samsung SSD 860 Pro - SANDRA And ATTO Disk Benchmark

Next we ran SiSoft SANDRA, 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 after the test system reached and idle state. Average read and write performance metrics are detailed below.

Synthetic Disk Benchmarking


The Samsung SSD 860 PRO 2TB drive we tested put up the best read and write scores in the SiSoft SANDRA physical disk benchmark. We're bumping into the limitations of the SATA interface with many drives today, but Samsung still manages to wring a couple of additional megabytes per second versus the competition.

ATTO Disk Benchmark
More Information 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, or the like.



Reads are very tightly grouped with the ATTO Disk Benchmark, but there is a bit of a delta separating the drives in the write test. The Samsung SSD 860 PRO performs well overall, but doesn't quite catch the leaders at the largest transfer sizes.
