8k Random Read/Write






Many server workloads rely heavily upon 8k performance, and we include this as a standard with each evaluation. Many of our server workloads also test 8k performance with various mixed read/write distributions.


The average 8K random read speed of the Samsung SM843T is 37,251 IOPS at 256 OIO -second only to the SM843 at 44,444 IOPS. The Micron P400M scores 35,551 IOPS, and the Intel DC S3700 measures 45,423 IOPS. The SM843T closes the performance gap with 8K data, which is crucial for the majority of real-world workloads.






The SM843T narrows the latency gap considerably with 8k read activity.




The SM843T averages a very consistent 9,695 IOPS; the P400M averages 15,345 IOPS; the SM843 averages 6,254 IOPS; and the DC S3700 averages 17,263 IOPS. The SM843T continues to offer extremely consistent performance in heavy random write workloads.






The Intel DC S3700 and Micron P400m separate themselves from the pack with very good 8k write latency.




The SM843T falls into the same performance profile we witnessed with the 4k write percentage testing.




Power consumption for the SM843T averages 3.41 watts, the SM843 averages 3.54 watts, the P400M averages 4.27 watts, and the DC S3700 averages 3.96 watts. Once again, the SM843T sports miserly power consumption figures.




The SM843T averages 2,847 IOPS per watt; the P400M averages 3,577 IOPS per watt; the SM843 averages 2,234 IOPS per watt; and the DC S3700 averages 4,328 IOPS per watt.
