ADDLINK S68 256GB M.2 NVME Gen3 Internal Solid State Drive ( SSD )

The Addlink S68 256GB is a compact M.2 2280 NVMe solid state drive built on the PCIe Gen3x4 interface running NVMe 1.3 protocol. It uses four PCIe lanes simultaneously for data transfer, enabling sequential read speeds of up to 2000 MB/s and sequential write speeds of up to 1200 MB/s as measured internally by Addlink using CrystalDiskMark. Actual speeds vary by system configuration, interface, and workload. For random workloads the S68 delivers up to 220K read IOPS and 250K write IOPS at 4K block size, making it well suited to demanding desktop and laptop applications. The drive uses 3D TLC NAND flash, which stacks memory cells vertically to overcome density limitations of planar NAND while maintaining strong endurance. The S68 supports Host Memory Buffer (HMB), allowing the drive to leverage a portion of system DRAM as a cache buffer, reducing latency on lower-cost NVMe controllers. Additional data integrity features include end-to-end data path protection, dynamic thermal throttling, SmartZIP, SmartRefresh, and Drive Log diagnostics. Hardware-level security is covered by TCG OPAL 3 and TCG Pyrite specifications, providing encryption management compatibility for enterprise and prosumer workloads. In the standard M.2 2280 form factor (80 mm × 22 mm × 3.5 mm max, 8.2 g), the S68 fits slim notebooks, compact desktop systems, and builds with limited space where a traditional 2.5-inch or mSATA drive would not suit. The drive operates between 0°C and 70°C and stores safely between −40°C and 85°C. Addlink rates it at a mean time between failures (MTBF) of 1.5 million hours and an endurance of 200 TBW (terabytes written), reflecting a drive intended for sustained daily workloads. The S68 is compatible with Windows 10, Windows 8 and Windows 7 (both require additional drivers), and Linux kernel 2.6.31 or later.
