M.2 B Key to SD 4.0 adapter

This Vszerda adapter converts an M.2 B key slot that carries a USB 2.0 bus into an SD 4.0 card reader. It accepts UHS-II cards and fits 3042 or 3052 form-factor modules. The device is aimed at laptop users who want to add removable SD storage through an available WWAN or similar M.2 B key opening.

Who this suits, who should look elsewhere

The adapter suits owners of laptops with a free M.2 B key slot wired for USB 2.0 who need a built-in SD 4.0 card reader. It is not for systems whose M.2 B key slot provides only PCIe lanes, nor for users who require the faster transfer rates of a USB 3.0 or PCIe-connected reader. Builders needing an M.2 storage drive or a second wireless card should look at other options.

  • USB 2.0 bus interface keeps installation driver-free
  • Fits 3042 and 3052 form-factor modules

Questions about this item

Should I choose the 3042 or 3052 length for my laptop's M.2 B Key slot?

Match the adapter length to your slot: use the 3042 version in a 3042 socket and the 3052 version in a 3052 socket; both fit M.2 B Key USB interfaces.

What does the USB 2.0 label mean for SD 4.0 UHS-II card speeds in practice?

The adapter connects through a USB 2.0 bus, so UHS-II cards operate at USB 2.0 throughput rather than their full UHS-II potential.
