128k sequential speed reflects the maximum sequential throughput of the SSD. The HGST Ultrastar SSD800MH is in its own league with the highest sequential read speed we have recorded from a single 2.5-inch SSD. It came in at 1,243 MiB/s. The Toshiba PX02SS goes toe-to-toe with the HGST SSD800MM in sequential read speed, with both delivering an average of 1,040 MiB/s and 1,056 MiB/s, respectively.

All three SSDs are very consistent, but the SSD800MH provides the lowest overall latency.

The SSD800MH sets another record with a sustained speed of 779 MiB/s, and the SSD800MM averages 702 MiB/s. The PX02SS scores slightly over its rated speed at 417 MiB/s. It is important to note that the PX02SS is not designed with sequential workloads in mind; its specification for sequential write is 410 MiB/s.
