Random Read Performance
The Toshiba BiCS FLASH is not as fast as Micron's 64L and 96L TLC in low queue depth random read performance. The Cardea Liquid manages to surpass 12,000 IOPS at QD1. That makes the drive very responsive under regular consumer workloads but not as fast as the three at the top of the chart using Micron TLC.
Random Write Performance
With modern SLC cache on NVMe SSDs, we just glaze over the random write performance. The SLC is so fast that it absorbs the burst writes coming from the host system. Datacenter and enterprise workloads require larger buffers to handle longer and sustained random write workloads. All of the drives in the chart today deliver excellent random performance in burst workloads.
