128K Sequential Read/Write
The 128K read sequential speeds reflects the maximum sequential throughput of the SSD using a realistic file size encountered in an enterprise scenario.
The P420m wears the read speed crown once again, pushing out a tremendous 3,336 MB/s at QD256. The P320h is no slouch, falling only slightly behind with an average of 3,064 MB/s.
The P420m averages 10ms at QD256, with the P320h trailing slightly with an average of 10.9ms.
The P320h provides a much higher average write speed of 1,891 MB/s at QD256, while the P420m delivers 614 MB/s. Sequential write environments are obviously not the target market for the P420m.
