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 Toshiba HK3R is 47,315 IOPS, the Samsung 845DC EVO is 52,731 IOPS, the Micron M500DC is 48,034 IOPS at 256 OIO, and the Intel DC S3500 measures 44,444 IOPS.
All four SSDs exhibit a tight latency range during the 8K random read test, with a much smaller performance variance between results than in the 4k testing.
The HK3R averages 9,656 IOPS, the M500DC easily leads with an average of 23,852 IOPS, the 845DC EVO comes in second with 7,112 IOPS, and the DC S3500 averages 6,937 IOPS.
The HK3R leads the DC S3500 and the 845DC EVO, but trails the M500DC by a large margin.
The mixed workload testing again reveals a tight crowd in the higher write mixtures, with the exception of the chart-topping M500DC.
Power consumption for the HK3R averages 3.91 watts; the 845DC EVO averages 3.54 watts, the M500DC averages 4.77 watts, and the DC S3500 averages 3.75 watts.
The HK3R averages 3,112 IOPS per watt, the M500DC leads the efficiency test with 4,877 IOPS per watt, the 845DC EVO averages 1,994 IOPS per watt, and the DC S3500 averages 1,584 IOPS per watt.
