2TB Class Performance Testing
Sequential Read Performance
The new 2TB 970 EVO Plus manages to outperform the 960 Pro to queue depth 2 in sequential reads. The EVO Plus shows a very large performance increase at low queue depths compared to the original 970 EVO it replaces.
Sequential Write Performance
The drive stumbled slightly at queue depth 2 in our sequential write test but eventually took off to wipe the floor with the older 2TB-class drives. The 970 EVO Plus is really in a class of its own writing sequential data in bursts.
Sustained Sequential Write Performance
This test, we write sequential 128KB data to all of the user-available area of the drives. The EVO Plus shows a faster, and larger, SLC buffer thanks to an improvement to the TurboWrite feature. This test also allows us to see the native 3-bit per cell write-speed post buffer. The new 92L flash is quite a bit faster than the older 64L memory.
Random Read Performance
The new EVO Plus improves on the random read performance set by its predecessor, but the new series still trails the older 960 Pro and the newer run of NVMe SSDs with Micron 64L flash, like the HP EX950 and ADATA SX8200 Pro.
Random Write Performance
The burst random write performance is the highest we've tested on a consumer NVMe SSD thus far. The 2TB 970 EVO Plus matches the 960 Pro at very low queue depths but manages to outperform the iconic drive-in peak IO.
70% Read Sequential Performance
Mixed IO is often overlooked, but it's one of the most important areas for real-world performance. The new EVO Plus is significantly faster than the generation it replaces in our sequential mix test.
70% Read Random Performance
Samsung also made gains in the random mix workload over the previous generation. The EVO Plus still trails the older 960 Pro and the SM2262EN drives like the EX950 but did close the gap in this area.
