Chip Component Analysis

SSD Controller

The eight-channel flash controller is a completely new model that looks to be an in-house design by Micron, possibly a result of their acquisition of Tidal Systems in 2015. Not a lot is known about the controller, and Micron is trying to keep details under wraps. Based on the details of the Crucial P5, we know it supports pseudo SLC caching and TLC, and has eight channels.

SSD Flash Chips

The two flash chips each have a capacity of 512 GB. They are 96-layer 3D TLC made by Micron.

SSD DRAM Chip

A Micron DDR4-4266 chip provides 1 GB of fast DRAM storage for the controller to store the mapping tables.
