In our throughput tests, the read performance saw a dip at the 1MB block mark but the drive recovered quickly to peak at the 8MB block mark at 940.25MB/s before dropping back slightly to finish the test run at 938MB/s. The peak write figure of 909.20MB/s came right at the end of the test run.
When it comes to read performance, the SanDisk Extreme Pro just edges ahead of all the USB 3.1 Gen 2 drives we’ve tested. The Seagate FireCuda Gaming SSD is still king of the hill for USB external drives thanks to its USB 3.2 Gen 2×2 interface.
As with the read performance, the write performance of the SanDisk Extreme Pro edges it just in front of all the other drives we’ve tested with the exception of Seagate’s FireCuda Gaming SSD.
