As with the ATTO benchmark results, we could confirm the official Sequential performance figures of the drive using our 128KB tests. The drive produced a read score of 3,496MB/s with writes at 3,024MB/s against the official 3,470MB/s reads and 3,000MB/s writes.

128KB Sequential Read Performance v QD

The read performance of the SN750 falls below the previous generation NVMe drive at QD2 but for QD's 1, 4 and 32 the new drive is the faster performer.

128KB Sequential Write Performance v QD

When it came to our Sequential write test, the new SN750 outshone the previous drive at all queue depths apart from QD1 where the older drive still has the advantage.
