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 subject's descent 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. We precondition for this test with an inverted (all-write) workload, so no relevant information can be gleaned from our preconditioning charts.
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, and 512KB = 1 percent.
Although our Web mix does not represent a completely accurate modern web server workload, it is a very taxing workload that does give us a realistic representation of how well an SSD handles an all-read mixed workload. This time Techman's XC100 is the closest competitor for the DC P4510 but it doesn't match or surpass the performance of our test subjects until well outside of the typical operating region of QD1-9. The DC P4510's performance get's surpassed by the 9100 MAX and the XC100 at high queue depths, but it's too little to late as we've seen throughout the entirety of this review.
This completes our battery of testing and cements our opinion that the DC P4510 is the best all-around performing flash-based enterprise SSD we've tested to date.
Conclusion (TL;DR): The DC P4510 was designed to flourish in a read-centric environment and the results of this test clearly show Intel hit the nail on the head.
