PCIe Gen3 x4 NVMe SSD · 512GB · M.2 2280
addlink S68 512GB NVMe SSD
Upgrade a compatible desktop or laptop with an M.2 NVMe drive built around PCIe Gen3 x4. The S68 combines a compact 2280 form factor with rated sequential speeds of up to 2,100MB/s read and 1,700MB/s write.
Designed for: everyday computing, faster system and application loading, game libraries and general storage upgrades on supported NVMe systems.

What the S68 offers
Uses four PCIe 3.0 lanes with the NVMe protocol for compatible M.2 storage slots.
Manufacturer-rated sequential read and write performance. Actual results depend on the host system, workload and available PCIe bandwidth.
Supports HMB, using a portion of system memory for drive-management tasks rather than relying on a dedicated DRAM cache.
3D NAND architecture with thermal-throttling control and error-correction features specified by addlink.

Compatibility before you buy
- Confirm that the motherboard or laptop has an M.2 2280 slot that supports PCIe NVMe storage.
- An M.2 connector alone does not guarantee compatibility: some M.2 slots support SATA only, while others support PCIe NVMe.
- The drive uses PCIe Gen3 x4. It may operate at a lower negotiated link speed if the host slot provides fewer PCIe lanes or an older generation.
- Check available physical clearance, heatsink requirements and the system manufacturer’s storage support list.

Frequently asked questions
Will this SSD work in any M.2 slot?
No. The slot must support PCIe NVMe and the 2280 drive length. An M.2 SATA-only slot is not compatible.
Is the S68 a PCIe Gen4 SSD?
No. The S68 is a PCIe Gen3 x4 NVMe SSD. Its actual link speed depends on the host slot.
Does it have a dedicated DRAM cache?
The 512GB S68 uses an HMB design rather than a dedicated DRAM cache.
Where can I check the manufacturer’s information?
Review the official addlink S68 product page for product-family information and specifications.
