Intern Mini-SAS-adapter DeLOCK 63918

The DeLOCK 63918 is an internal Mini‑SAS adapter that allows connection of NVMe storage devices (for example U.2 SSDs) with an SFF‑8643 interface to a system M.2 slot. The adapter uses an M.2 2242 form factor with a 67‑pin M.2 Key M connector on the host side and a 36‑pin SFF‑8643 Mini‑SAS connector on the device side. It supports a maximum data transfer rate of 32 Gbit/s and comes in a compact black design. Made in Taiwan, the adapter is intended for reliable internal use in desktop or server systems.

Advantages

The adapter provides a simple internal conversion from M.2 to Mini‑SAS (SFF‑8643) without external power or complex cabling. With support for up to 32 Gbit/s it enables high‑speed data transfer for NVMe devices while keeping a compact M.2 2242 footprint. The integrated 67‑pin M.2 Key M connector and SFF‑8643 connector ensure compatibility with standard M.2 slots and Mini‑SAS NVMe storage modules.

Suitable for

• Connecting U.2 or other NVMe drives with SFF‑8643 interface to an M.2 Key M slot
• Internal upgrades in desktop PCs and workstations
• Server environments requiring compact NVMe connectivity via M.2

How to use

Install the adapter into a free M.2 Key M slot on the motherboard, ensuring correct alignment of the 67‑pin connector. Secure the M.2 module per the motherboard’s mounting method. Connect the NVMe device using a compatible Mini‑SAS (SFF‑8643) cable or connector to the adapter’s SFF‑8643 port. After installation, power on the system and verify that the drive is detected in firmware/OS. Follow the NVMe device manufacturer’s instructions for initialization and formatting if required.

Recommendations

Use the adapter only with compatible M.2 Key M slots and SFF‑8643 NVMe devices. Ensure your motherboard supports the necessary PCIe lanes for NVMe operation and that the system firmware is up to date. Avoid excessive mechanical stress on connectors during installation and confirm cooling is adequate for high‑performance NVMe drives.
