Toshiba XG5 NVMe SSD Review: Strong Performance With 64-Layer BiCS 3D Flash
Toshiba XG5 - SANDRA And ATTO Benchmark
Next we ran SiSoft SANDRA 2016 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 XG5 put up the best write numbers of the bunch. Read performance was also very good, and trails only the Samsung SSD 960 EVO.
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 XG5 put up some good numbers in the ATTO disk benchmark, and had the best write scores for a portion of the test, with medium-sized transfers. Reads were good as well, but trailed behind the Samsung drives.
