SanDisk rates the 8TB Desk Drive at up to 1,000MB/s for Sequential reads. In our throughput tests, the drive didn't quite hit that official maximum with a peak read figure of 932.22MB/s (16MB block). The spec sheet for the drive didn't have any write performance figures but in our throughput test, the drive peaked at the end of the test (16MB block) at 970.54MB/s.
In the read-throughput test, the drive peaked at the 16MB Block, right at the end of the test run at 932.227MB/s. Although some way short of the official maximum of 1,000MB/s, the drive is still one of the fastest we've seen using a USB 3.2 Gen 2 x1 interface.
As with the read test, the write throughput test saw the drive peak at the end of the test with a result of 970.54MB/s. We couldn't find an official write figure for the drive, but that figure of 970.54MB/s puts it among the fastest drives for writes using the interface.
