Toshiba OCZ RC100 SSD Review: Tiny, Affordable NVMe Storage
Toshiba OCZ RC100 NVMe 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.

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.
To this point, the OCZ RC100 drive hasn't been painting the rosiest picture of performance, but keep in mind these drives are meant to push costs down and bring NVMe drives to even more affordable price points. The drives trailed overall, especially as the transfer size surpassed the 8K mark, but these drives aren't meant to be speedsters...
