Mixed Workload Performance
70% Read Sequential Performance
Toshiba has a long history of producing SSDs with strong mixed workload performance. The 1TB BG4 manages to outperform all of the other drives in this test at QD2, the lowest depth we can measure in (because you can't read and write at the same time with a single IO).
70% Read Random Performance
The drive also performs well with random mixed workloads but only manages to score in the middle of the pack of the comparison drives in the chart at QD2. At higher queue depths, the BG4 picks up the pace and becomes more competitive.
