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 Toshiba HK3R2 averages 521 MB/s, and the Samsung 845DC EVO squeaks by with an average of 526 MB/s at 256 OIO. The Micron M500DC averages 417 MB/s, while the Intel DC S3500 delivers an average of 441 MB/s.






The 845DC EVO and the HK3R2 place very close in latency metrics during the measurement window.




Sequential write performance is important in tasks such as caching, replication, HPC, and database logging. The Toshiba HK3R2 takes a big lead in this test with an average of 488 MB/s. The 845DC EVO trails with 427 MB/s, the M500DC averages 388 MB/s, and the DC S3500 averages 424 MB/s.






The HK3R2 separates itself from the pack with a very consistent latency profile.




The HK3R2 manages to dethrone the M500DC in mixed sequential performance, which is a tall order considering the gulf between the two leaders.




The HK3R2 continues to impress with sequential workload performance as it averages 3.66 watts, the 845 DC EVO averages of 4.14 watts, the M500DC averages 5.24 watts, and the DC S3500 averages 4.83 watts.




The Toshiba HK3R2 leads the efficiency chart easily with 133 MB/s per watt; the 845DC EVO averages 99 MB/s per watt, the M500DC averages 73 MB/s per watt, and the DC S3500 averages 87 MB/s per watt.
