ADDLINK S90 1TB M.2 NVME Gen4 Internal Solid State Drive ( SSD )

The Addlink S90 1TB is a high-performance M.2 2280 internal solid-state drive built on the PCIe Gen4 x4 interface with NVMe 1.3 protocol. It is designed for users who demand fast sequential throughput without compromise — whether building a gaming PC, a creative workstation, or a high-demand desktop system. At the core of the S90's performance is its PCIe Gen4 x4 interface, which uses four lanes simultaneously to deliver sequential read speeds of up to 5,000 MB/s and sequential write speeds of up to 4,400 MB/s. For workloads that depend on small-file access patterns, the drive achieves up to 750,000 IOPS random read and 700,000 IOPS random write, making it well suited for multitasking, game loading, and intensive file operations. The S90 uses 3D TLC NAND flash and is supported by an external DDR4 DRAM cache (dual channel), which helps maintain consistent throughput during sustained transfers and improves the efficiency of SLC caching. The SLC caching mechanism provides a fast-write buffer that absorbs burst workloads before committing data to the main NAND array. Reliability is addressed through a RAID engine paired with LDPC (Low-Density Parity Check) error correction coding. Additional protective features include wear leveling, bad block management, over-provisioning, Garbage Collection, S.M.A.R.T. monitoring, TRIM support, DEVSLP power states, and RAID Protection — all working together to extend the usable life of the drive. Endurance is rated at 1,800 TBW (terabytes written) with an MTBF of 1.8 million hours, and Addlink backs this drive with a 5-year warranty (subject to the 1,800 TBW limit). The drive operates between 0°C and 70°C and has a storage temperature range of -40°C to 85°C. The S90 is backward compatible with PCIe 3.0 platforms, though full Gen4 speeds require a compatible Gen4 motherboard and CPU. AMD Ryzen 3rd-generation or later processors paired with an X570 or newer chipset motherboard are referenced in the product documentation as confirmed compatible configurations.
