Toshiba BG4 SSD Review: Mini But Mighty NVMe Storage

Next we used SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant for some quick tests. 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 partitions. Read and write performance metrics are detailed below.

ATTO Disk Benchmark More Information Here: http://bit.ly/btuV6w

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 BG4 once again outpaces the Intel SSD 760P and WD Blue drives according to ATTO's write test, at least until it hits the 512KB transfer size, at which point performance tapers off. The read tests shows the same performance trend, with performance tapering at the larger transfer sizes, but the BG4 is out in front of only the WD drive for the early part of the test.
