Description
Part numberSGAMMIXS55-1T-C
The ADATA XPG GAMMIX S55 1TB (SGAMMIXS55-1T-C) is a compact high-performance PCIe Gen4 NVMe SSD designed for modern laptops, handheld gaming devices, mini PCs, and compact desktop builds. Built using the PCIe Gen4 x4 interface, it delivers sequential speeds of up to 5,000 MB/s read and 3,700 MB/s write, offering roughly three times the performance of standard PCIe Gen3 SSDs.
The drive uses 3D NAND flash memory with intelligent SLC caching, helping improve data throughput and responsiveness when launching applications, transferring files, or loading games.
One of the standout features of the GAMMIX S55 is its ultra-compact M.2 2230 form factor (30 × 22 mm). This small footprint makes it ideal for handheld gaming consoles, ultrabooks, mini PCs, and other space-constrained devices where larger M.2 2280 drives cannot fit.
The SSD supports NVMe 1.4 and integrates advanced reliability technologies including LDPC error correction and wear-levelling, ensuring stable performance and long-term durability. With endurance ratings around 250 TBW and an MTBF of 1.5 million hours, the GAMMIX S55 offers dependable performance for everyday computing, gaming, and mobile productivity workloads.
Whether you’re upgrading a handheld gaming device, expanding storage in a compact laptop, or improving performance in a small-form-factor system, the XPG GAMMIX S55 delivers excellent speed and reliability in an ultra-compact design.
