This test emulates Database and On-Line Transaction Processing (OLTP) workloads. OLTP is in essence the processing of transactions such as credit cards and high frequency trading in the financial sector. Enterprise SSD's are uniquely well suited for the financial sector with their low latency and high random workload performance. Databases are the bread and butter of many enterprise deployments. These are demanding 8K random workloads with a 66% read and 33% write distribution that can bring even the highest performing solutions down to earth.
As we begin to delve into our mixed workload benchmarks it is important to note, again, that we test the Kingston E100 with 50% compressible data. OLTP and Database workloads tend to be highly compressible, so in real deployment performance may be higher than represented in these tests. Other workloads we test may also tend to have different compression ratios, so it is important to understand the workload and adjust purchasing decisions accordingly.
The Kingston E100 averages 31,668 IOPS during the measurement window, with a similar amount of variability in comparison to the Optimus and the Intel DC S3700.
The Kingston E100 provides 4,431,590 I/Os (46.8%) at 6-8ms, and 3,114,547 I/Os (32.9%) at 8-10ms. There is a wide range of command latency for the E100, ranging from .2-.4ms to 60-80ms.
The Kingston E100 averages 4.66 Watts during the precondition run.
The Kingston E100 averages 6,777 IOPS per Watt, with the variability again lending some clutter to the chart. The Micron P400m averages 7,422, the Intel 9,418, and the Optimus 5,659 IOPS per Watt.
The Webserver profile is a read-only test with a wide range of file sizes. Web servers are responsible for generating content for users to 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 that is hosting the website, and thus the end-user experience.
The Kingston E100 averages 22,042 IOPS, matching the Micron P400m and the Intel DC S3700.
The Kingston E100 provides 5,093,605 I/Os (77%) in the 10-20ms range, and 1,365,971 I/Os (20.7%) in the 8-10ms range.
The E100 averages 4.01 Watts during the measurement window.
The E100 averages 5,471 IOPS per Watt.
