128k Sequential Read/Write
128k sequential speed reflects the maximum sequential throughput of the SSD. The Micron M500DC features the lowest sequential performance specifications of the value-SSD lineup. The M500DC weighs in with a sequential read speed of 417 MB/s. The Intel DC S3500 delivers an average of 441 MB/s, and the Samsung SM843 averages a commanding 528 MB/s.
The SM843 provides the lowest overall latency.
The M500DC averages 388 MB/s. The DC S3500 averages 424 MB/s, and the SM843 delivers another win with 501 MB/s.
On the surface, the SM843 would appear to be the best SSD with sequential read and write activity. Our mixed workload testing reveals otherwise. The SM843 and DC S3500 both exhibit a 'bathtub' performance profile with sequential workloads. This is identified by the high marks in pure read/write environments, but sagging performance in the middle. The slightest of mixed workloads sends their performance much lower, while the M500DC delivers steadier performance throughout the test. The SM843 and DC S3500 actually only lead in two of the 11 tests, and the M500DC provides superior mixed sequential workload performance.
The M500DC averages 5.24 watts. The DC S3500 averages 4.83 watts, and the SM843 requires 3.65W for the sequential write workload.
The M500DC averages 73 MB/s-per-Watt; the DC S3500 averages 87 MB/s-per-Watt, and the SM843 leads with a convincing 136 MB/s-per-Watt.
