I forgot to include it on this graph, but the SN850X does not quite take the write speed crown in ATTO that honor belongs to the SK hynix Platinum P41.

The SN850X does almost as well in ATTO as it does in CrystalDiskMark. WD SN850X 1TB ATTO 256MB WD SN850X 2TB ATTO 256MB Chart

ATTO was tested at both 256MB and 8GB file sizes. The ATTO Disk Benchmark has been a staple of drive sequential performance testing for years. Once again, the sequential write speed on this drive is the top result for any 1TB drive I have tested. Just as I like to see, the move to the larger CrystalDiskMark test has a negligible effect on the SN850X.

The WD SN850X 1TB fares well in CrystalDiskMark.

We test using both the default smaller test size as well as larger test sets on our benchmarks. This allows us to see the difference between lighter and heavier workloads.
