Internals, Testing Methodology and System Setup


Comparing to P3700:

After noting that the PCB / layout of the P3520 was virtually identical to the compared P3700, I opted to not risk damage disassembling this one. Instead, here is the disassembled pic of the P3700:

Alright, so the only real differences here are some more DRAM to support the higher capacity and NAND packages containing IMFT 3D NAND operating in MLC mode. Same 18-channel controller with only minor firmware tweaks to support and optimize for the new type of flash.

Testing Methodology

This is our first review using a purpose-built enterprise testing suite. We will cover the methodology further into the review and welcome your feedback on our process and presentation.

Test System Setup

We have several storage testbeds, but for this piece we used the same setup used in our 5-way SSD 750 RAID testing. It is not server-class hardware, but it is a reasonable equivalent that allows us to push the CPU to higher clock speeds than server hardware would normally be capable of. This helps shift the burden / bottlenecks to the NVMe PCIe SSDs under test.

PC Perspective would like to thank Intel, ASUS, Corsair, Kingston, and EVGA for supplying some of the components of our test rigs.
