Introduction

ADATA is Taiwan's largest manufacturer of flash storage and DRAM memory for computers. They have been at the forefront of SSD development for many years, bringing us famous SSDs like the SX8200, SX900, and Gammix S70.

XPG is one of ADATA's sub-brands and creates products optimized for the needs of gamers.



Today, we are reviewing ADATA's new Atom 50 SSD, which is priced extremely competitively for a PCIe 4.0 SSD, just $120 for the reviewed 1 TB variant makes it the most affordable Gen 4 SSD by far. Under the hood, we found a brand-new Innogrit IG5220 controller paired with the newest 176-layer 3D TLC flash from Micron. A DRAM cache is not available for the mapping tables of the SSD—a reasonable cost optimization for a solid-state drive targeting today's consumer workloads.

The ADATA XPG Atom 50 is only available in one capacity: 1 TB, for $120 as mentioned before. Endurance is set to 640 TBW for this model, ADATA includes a five-year warranty with the Atom 50.
