ADATA Technology is one of the world's leading manufacturers of high performance memory modules and data storage solutions. Founded in 2001 with a staff of 20, this Taiwanese company set itself apart from the competition early on thanks to its professionalism, industry know-how and eye-catching product designs. Today, ADATA continues to lead the way through constant innovation and development of products that exceed customer expectations. Backed by technical expertise, state-of-the-art manufacturing facilities and premium customer service, ADATA currently offers a variety of products including DRAM modules, USB flash drives, memory cards, solid state drives and portable hard drives.

This past fall, ADATA launched its XPG ATOM series SSDs. In addition to two new PCIe 3.0 drives, the ATOM 30 and 40, the company unveiled its latest PCIe 4.0 SSD, the ATOM 50. Designed for use in high-end desktops and Sony's PS5 gaming console, this M.2 form factor drive is powered by Innogrit's RainierQX (IG5220) controller and is available with 1TB of 176-layer 3D TLC NAND flash. The ATOM 50 also utilizes SLC Caching and HMB (Host Memory Buffer) to accelerate read and write performance as well as Low-Density Parity Check (LDPC) code technology and AES 256-bit encryption to ensure data security and integrity. To top it all off, the drive is equipped with a slim, aluminum heatsink as well as an ultra-fast PCIe Gen4 x4 NVMe 1.4 interface.

The ATOM 50 is currently available in a 1TB capacity and is capable of delivering up to 5,000 MB/s sequential read and 4,500 MB/s sequential write speeds as well as up to 650,000 random read and 600,000 random write IOPS.
