Intel DC P3520 Enterprise NVMe SSD Review (1.2TB) – With 3D NAND Comes Value


Our last set of profiles include both File Server and Web Server workloads. As mentioned before the last hour of preconditioning, the average IOPS, and average latency for each QD is graphed below.

The File Server profile is based on an 80% read/20% write mix. It’s made up of block sizes from 512 to 64K, each making up a different percentage of the access pattern. The pattern is: 512 bytes=10%, 1k=5%, 2k=5%, 4k=60%, 8k=2%, 16k=4%, 32k=4%, 64k=10%.

In the file server profile test, it maintained an average latency of under 2ms up to QD64 and delivered an average of 36K IOPS from QD64 on.

The Web Server profile is similar to the File Server profile, but has some additional 128K and 512K accesses thrown in for good measure. Additionally, the profile is 100% reads.

Finally, during the web server profile, we see that the Intel DC P3520 is, again, at the end of the pack. These results, however, are still more than triple and up to five times the performance of many of the enterprise SATA SSDs we have tested.

    Looks like solid piece. But I still wait for real optane.
