Toshiba BG4 NVMe SSD Review: PCMark Storage 2.0 Tests
We like PCMark's Storage 2.0 benchmark module for its real-world application measurement approach to testing. PCMark offers a trace-based measurement of system response times under various scripted workloads of traditional client / desktop system operation. From simple application start-up performance, to data streaming from a drive in a game engine, and video and photo editing with Adobe applications, we are comfortable that these tests reasonably illustrate the performance profile of SSDs in an end-user / consumer PC usage model, more so than a purely synthetic transfer test.

The trace-based PCMark tests show the Toshiba BG4 in a very favorable light. Although the deltas separating the drives are quite small here, the BG4 pulls off a second place finish in terms of bandwidth and the overall score. Although the DRAM-less, single-chip design is not conducive to leading-edge performance across the board, Toshiba has obviously tuned the drive for common consumer workloads, as evidenced by its 4K low queue depth performance and its performance here.
