128K Sequential Read/Write
The 128K sequential speeds reflect the maximum sequential throughput of the SSD using a realistic file size actually encountered in an enterprise scenario.
The Micron averaged 413MB/s in sequential reads at QD256, the Intel DC S3700 averaged 473MB/s, and the Optimus averaged 526MB/s. All three SSDs exhibit very good consistent performance in the read testing, though the Intel tends to slip back into its garbage collection mode intermittently.
The Micron averages 318MB/s in 128K sequential write speed, the DC S3700 averages 444MB/s, and the Optimus weighs in at 514MB/s.
The Micron P400m provides 51.6% (394,224 I/Os) in the 80-100ms range, and 48% (369,021 I/Os) in the 100-200ms range.
The Micron P400m averages 5.57 Watts during sequential writes, the Intel averages 2.39 Watts, and the Optimus averages 7.37 Watts. The P400M gives 57MB/s IOPS per Watt, the DC S3700 gives 185MB/s per Watt and the Optimus scores 69MB/s per Watt.
