The Drive

SSD Front
SSD Back

The drive uses the M.2 2280 form factor, which makes it 22 mm wide and 80 mm long.

SSD Interface Connector

While most other M.2 NVMe SSDs transfer data over the PCI-Express 3.0 x4 interface, the ADATA XPG Atom 50 connects to the host system over a PCI-Express 4.0 x4 interface, which doubles the theoretical bandwidth.

SSD Teardown PCB Front

On the PCB, you'll find the controller and two flash chips. The other side of the PCB is empty.

Inside the package, you'll find this metal heatspreader heatsink. It's not preattached, but installation is super easy. Just peel off the tape and stick it onto your SSD. Our thermal testing later in this review shows that the heatsink isn't required at all, as there is no throttling even without the heatsink.

Chip Component Analysis

SSD Controller

This is the first time we're testing an SSD with the Innogrit IG5220 RainierQX controller. This controller is optimized for low-cost Gen 4 designs without DRAM and manufactured on a 12 nanometer production process.

SSD Flash Chips

The two flash chips are Micron 176-layer 3D TLC NAND. They have been rebranded by ADATA. Each chip has a capacity of 512 GB.
