128k sequential speed reflects the maximum sequential throughput of the SSD, and is indicative of performance in OLAP, batch processing, streaming, content delivery applications, and backup scenarios.

 

The 400GB 845DC PRO leads again with an average of 495 MB/s at 256 OIO, mirrored by the 400GB 845DC PRO with 495 MB/s. The Micron M500DC features the lowest sequential performance specifications of the lineup, and averages 417 MB/s, while the Intel DC S3700 delivers an average of 474 MB/s.
