The WD Black NVMe produced very strong figures for both read and writes in out throughput test, without any serious drops in performance on the way to peaks of 2,829.92MB/s for reads and 2,727.63MB/s for writes.
The WD Black NVMe showed the fastest average read and write throughput speeds when compared to three other recently tested drives, but bear in mind the Intel 760p and Kingston A1000 drives are entry level NVMe drives whereas the Black NVMe is very much a performance drive.
