Addlink S68 256GB M.2 NNMe SSD

The Addlink S68 256GB NVMe SSD is a compact, high-performance storage solution designed for PC builders, gamers, and professionals who want to move beyond traditional SATA drives without stretching their budget. Built around the PCIe Gen3 x4 interface with NVMe 1.3 protocol, the S68 leverages four simultaneous data lanes to deliver sequential read speeds of up to 2000 MB/s and sequential write speeds of up to 1200 MB/s — figures measured using CrystalDiskMark in internal testing by Addlink. These speeds translate to noticeably faster OS boot times, quicker application launches, and reduced level-load times in games compared to SATA-based drives. The drive employs 3D TLC NAND flash, a technology that stacks memory cells vertically to overcome the density and endurance limitations of older planar (2D) NAND designs. This architecture supports a rated total bytes written (TBW) endurance of 200 TBW for the 256 GB capacity, making it suitable for sustained write-intensive workloads over the drive's rated lifespan. A mean time between failures (MTBF) of 1.5 million hours further underscores its reliability credentials. Addlink has equipped the S68 with several data-integrity and stability features. Host Memory Buffer (HMB) support allows the drive to use a portion of system DRAM as a cache proxy, helping maintain consistent performance without a dedicated DRAM chip on the drive itself. An ECC (error-correcting code) algorithm monitors and corrects bit-level errors in real time, while dynamic thermal throttling protects the drive from heat-related performance degradation. End-to-end data path protection, SmartZIP, and SmartRefresh round out the firmware feature set. TCG OPAL 3 and TCG Pyrite security standards are supported, enabling hardware-based encryption compatibility for enterprise and security-conscious users. Mounting in the industry-standard M.2 2280 form factor (80 mm × 22 mm × 3.5 mm max height, 8.2 g), the S68 fits thin-and-light laptops, mini-ITX desktops, and systems with limited internal space. It replaces legacy mSATA and mini-PCIe slots via the M.2 multi-purpose connector. Compatible operating systems include Microsoft Windows 10 natively, Windows 7 and Windows 8 with additional drivers, and Linux kernel 2.6.31 or later.
