Our take on the A-Data Technology XPG SX8100 Internal SSD 4TB

The ADATA XPG SX8100 is a PCIe Gen3 x4 NVMe M.2 SSD that uses 3D TLC NAND and a DRAM cache buffer to reach sequential read speeds up to 3500 MB/s and write speeds up to 3000 MB/s. It is aimed at gamers, content creators, and DIY builders who need fast storage for large files and applications. The 4TB capacity is generous for its class, but the drive lacks a heatsink and its Gen3 interface trails newer Gen4 drives in peak speed. Reviewers generally praise its performance and endurance for the price, though some note it runs warm under sustained loads.
