Samsung SSD 960 Pro NVMe M.2 Review: Blazing Fast, Solid State 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 Pro 1TB drive trailed the Intel SSD 750 and essentially tied with the previous-gen SSD 950 Pro in the read test, but it pulled way out in front of all of the other drives in the write portion of this benchmark.
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 Pro 1TB drive we tested here put up the best numbers we have seen from a single solid state drive in the ATTO Disk Benchmark to date. At all transfer sizes, in both the read and write portions of this benchmark, the SSD 960 Pro led the pack by significant margins. Also note, that peak transfers were within the 3.5GB/s (read) and 2.1GB/s (write) ranges here, which is exactly where Samsung specs the drives.
