In our read throughput test, the 1TB Black SN770 peaked at 4,241.74MB/s at the 8MB block mark. That test result is some way off the official maximum of 5,150MB/s.

The peak read throughput test result of the Black SN770 sees it in the bottom half of our results chart.

Peak write throughput came at the 4MB block mark at 4,490MB/s, again slower than the official maximum figure of 4,900MB/s.

As with the read throughput test, the write test result sees the drive in the bottom half of the table.
