Chip Component Analysis

SSD Controller

The eight-channel flash controller is made by Marvell. Once a leader in SSD controller chips, seeing one of their chips on a modern SSD is quite rare. Their 88SS1092 was released around 2018. Internally, it uses a triple-core ARM Cortex R5 controller running at up to 500 MHz.

SSD Flash Chips

The two flash chips each have a capacity of 512 GB. They have been rebranded by Longsys, Lexar's parent company, which buys up bulk unpackaged flash chips, tests them in their facilities, and packages them.


A Nanya DDR3-1866 chip provides 1 GB of fast DRAM storage for the controller to store the mapping tables in.
