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


Sequential performance is measured similarly to the other two tests before. The drive is first secure erased to get it in a clean state. Next, we precondition the drive with a 128KB sequential write workload at QD256 until the drive is in a steady state. Finally, we cycle through QD1-256 for 5 minutes each for writes and then reads. All this is scripted to run with no breaks in between. The last hour of preconditioning, the average MB/s, and average latency for each QD is graphed below.

Unsurprisingly, the Intel DC P3520 delivers very good sequential write performance and consistency, except for a small blip see at just before the 18,000-second mark.

During sequential read the Intel DCP 3520 averaged 1,600MB/s after QD16, which is surprisingly lower than the rated spec of 1,700MB/s.

In contrast to its sequential read performance, during sequential write testing, the Intel DC P3520 performs magnificently. It averages 1,300MB/s from QD1 on, which is in line with its rated specification, and trails just behind the Techman XC100 1.6TB.

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