We precondition the drive for 16,000 seconds, or 4.44 hours, receiving performance data every second. We plot this data to observe the test subjects decent into steady state. We plot both IOPS and Latency. We plot IOPS (represented by blue scatter) in thousands and Latency (represented by orange scatter) in milliseconds. Steady state is achieved at 4,500 seconds.

The Web Server workload is a pure random read test with a wide range of file sizes. Our test consists of the following file sizes and corresponding percentage of the overall 100 percent workload file size: 512B = 22 percent, 1KB = 15 percent, 2KB = 8 percent, 4KB = 23 percent, 8KB = 15 percent, 16KB = 2 percent, 32KB = 6 percent, 64KB = 7 percent, 128KB = 1 percent, 512KB = 1 percent.

The 845DC dominates this test. Micron's M510DC does not do as well with a wide distribution of file sizes. At QD32, the 845DC EVO leads the M510DC by over 13,000 IOPS. The M510DC doesn't perform unusually badly in this test, it's more accurate to say the 845DC EVO performs exceptionally well with this demanding random read workload.

Conclusion: The M510DC will provide vastly superior performance to HDD's in this type of environment, however, other SSD options are faster for this particular workload.
