Toshiba XG6 NVMe M.2 SSD: SANDRA And ATTO Benchmarks

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.

The Toshiba XG6 continues to compete well with the WD and Samsung drives, but can't quite catch them in the SANDRA Physical Disk Test. Regardless, reads and writes north of 2.9GB/s and 2.2GB/s are nothing to sneeze at.

ATTO Disk 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 Toshiba XG6 performed very well in the ATTO Disk Benchmark. Writes tapered off once the transfer size exceeded 32MB, but otherwise led the pack for a large portion of the test. Reads were also very good, and trailed only the WD Black overall, though the Samsung and Intel drives had a clear advantage at smaller transfer sizes.
