This test consists of Database and On-Line Transaction Processing (OLTP) workloads. OLTP is the processing of transactions such as credit cards and high frequency trading in the financial sector. Databases are the bread and butter of many enterprise deployments. These demanding 8k random workloads with a 66 percent read and 33 percent write distribution bring even the best solutions down to earth.


The HK3R2 averages 22,525 IOPS, but suffers much of the same variability as the M500DC, whose average of 21,133 IOPS takes second place. The Samsung 845DC EVO has a very consistent average of 19,678 IOPS at 256 OIO, and the Intel DC S3500 averages 19,400 IOPS at 256 OIO.






The HK3R2 makes a solid gain in latency vs IOPS performance in comparison to its predecessor, and takes the lead in this test.




The HK3R2 averages 3.30 watts, the 845DC EVO averages 3.55 watts, the M500DC averages 2.76 watts, and the DC S3500 averages 3.76 watts.




The chart gets muddy with several SSDs in close competition. HK3R2 averages 7,062 IOPS-per-watt, the 845DC EVO averages 5,465 IOPS-per-watt, the M500DC averages 7,676 IOPS-per-watt, and the DC S3500 averages 4,040 IOPS-per-watt.



Web Server






The Web Server workload is read-only with a wide range of file sizes. Web servers are responsible for generating content users view over the Internet, much like the very page you are reading. The speed of the underlying storage system has a massive impact on the speed and responsiveness of the server hosting the website.


The HK3R2 leans on its impressive random read speed to take the lead in this test with an average of 28,796 IOPS at 256 OIO; the 845DC EVO averages 28,054 IOPS, and the M500DC averages 18,650 IOPS, falling to the DC S3500 average of 23,664 IOPS.






The HK3R2 pulls away from the 845DC EVO in this workload.




The HK3R2 averages 3.62 watts, the 845DC EVO averages 3.55 watts, the M500DC averages 3.21 watts, and the DC S3500 requires 3.8 watts during the fileserver workload.




The HK3R2 averages 1,303 IOPS-per-watt, the 845DC EVO scores 914 IOPS-per-watt, and the M500DC scores 1,965 IOPS-per-watt, in comparison to 749 IOPS for the DC S3500.
