128k Sequential Read/Write
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 PM53T and the 845DC EVO lead the sequential read tests with a similar average of 526MB/s at 256 OIO. The Micron M500DC features the lowest sequential performance specifications of the value-SSD lineup and averages 417 MB/s, while the Intel DC S3500 delivers an average of 441 MB/s.
The two Samsung entrants are practically indistinguishable in sequential read latency performance.
Sequential write performance is important in tasks such as caching, replication, HPC, and database logging. The PM853T averages 416 MB/s, nudged out of first by the 845DC EVO, which averages 427 MB/s. The M500DC averages 388 MB/s, and the DC S3500 is within striking distance with 424 MB/s.
The two Samsung SSDs deliver excellent performance in this test, but the DC S3500 closes the gap with the leader at higher OIO.
The M500DC is hard to beat during the mixed sequential workload testing, but the PM853T puts forth a valiant effort, and does so with a tighter performance profile during the majority of the test.
The PM853T averages 4.59 watts; the 845 DC EVO wins with an average of 4.14 watts; the M500DC averages 5.24 watts; and the DC S3500 averages 4.83 watts.
The PM853T averages 90 MB/s per watt; the 845DC EVO is the most efficient drive in sequential write environments with an average of 99 MB/s per watt; the M500DC averages 73 MB/s per watt; and the DC S3500 averages 87 MB/s per watt.
