M.2 SATA and mSATA to 2.5" Adapter

This adapter converts M.2 SATA NGFF and mSATA solid-state drives into a standard 2.5 inch SATA form factor. It supports B-key and B-plus-M-key modules in 2280, 2260 and 2242 lengths. The board includes a toggle switch to select between the two installed drives, but only one operates at a time. Builders upgrading laptops or desktops with legacy SATA bays can reuse existing drives without an external enclosure.

Sustained transfer limited by SATA III

The SATA III interface caps sequential throughput at 6 Gbps, so real-world speeds plateau around 500 MB/s regardless of drive rating. The aluminium casing acts as a passive heatsink, keeping the controller and NAND within safe temperatures during long cloning or backup sessions. No active cooling is required, and the compact dimensions of 3.94 by 2.75 by 0.275 inches fit tight drive cages without airflow obstruction.

B-plus-M key SATA only — no NVMe support

The single specification that decides compatibility is the keying: only M.2 SATA drives with B or B-plus-M keys work. Any drive labelled NVMe, PCIe or M-key is electrically incompatible and will not be detected. The adapter does not translate protocols, so NVMe SSDs from Samsung 980 series, WD SN series, Crucial P3 series and similar models cannot be used with this board.

Questions about this item

Does the adapter generate noticeable heat or noise when an M.2 SATA SSD runs continuously?

The compact black casing is designed to dissipate heat quickly and has no moving parts, so it operates silently during all-day use.

What host connection must my system already provide for this adapter to function?

A standard 2.5-inch SATA port and a SATA power connector are required; the adapter itself does not add a USB or PCIe interface.

Can I keep using my existing 2.5-inch SATA drive alongside an M.2 SATA SSD in the same drive bay?

Only one drive works at a time — the switch selects either the M.2 SATA or mSATA slot, so both cannot be active simultaneously.
