In our throughput tests, we couldn't quite get to the official maximum read/write figures of 1,050MBs and 1,000MB/s respectively but at 920MB/s we were much nearer the official read figure than the write (887MB/s). Comparing the latest My Passport SSD to the first generation drive shows the huge performance gain by using an NVMe SSD / USB 3.2 Gen 2 combination over the SATA III M.2 / USB 3.1 based original drive.
Read throughput peaked at the 8MB block mark at 932.63MB/s before tailing off to finish the test run at 920.94MB/s.
As with the read throughput test, the peak write figure came at the 8MB block mark at 890.94MB/s before dropping very slightly to 887.96MB/s at the end of the test run.
