TechPowerUp published a review on the ADATA XPG Atom 50 2 TB
A quote from the article:
The ADATA XPG Atom 50 is now available in a 2 TB variant. Unlike the 1 TB model, which used an Innogrit controller, the 2 TB version is built using Silicon Motion's new SM2269 XT controller, which supports PCI-Express 4.0, and DRAM-less operation.ADATA XPG Atom 50 2 TB Review
