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 HK3R2 is 50,560 IOPS at 256 OIO, the Samsung 845DC EVO measures 52,731 IOPS, the Micron M500DC measures 48,034 IOPS, and the Intel DC S3500 measures 44,444 IOPS.






The HK3R2 places second in the latency testing.




The HK3R2 averages 10,357 IOPS, the M500DC leads with an average of 23,852 IOPS, the 845DC EVO comes in third with 7,112 IOPS, and the DC S3500 averages 6,937 IOPS.






The HK3R2 leads the DC S3500 and the 845DC EVO, but trails the M500DC by a large margin.




The test field separates into two clear groups as we mix in more write activity, with the HK3R2 and M500DC coming out on top.




Power consumption for the HK3R2 averages 3.68 watts; the 845DC EVO averages 3.54 watts, the M500DC averages 4.77 watts, and the DC S3500 averages 3.75 watts.




The HK3R2 averages 2,683 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.
