In this review the reviewer looks at the Generic BASEQI UHS-II Aluminum microSD Adapter designed specifically for the 2021 M1 MacBook Pro 14' and 16'. The bottom line is simple: this adapter is for users who need discreet, easily expanded storage that sits completely flush with the MacBook body; it provides up to 2TB of extra space and supports both UHS-II and UHS-I microSD cards so you can choose capacity and speed independently. If you want a hidden, solid-feeling option to add storage without external dongles, this adapter delivers that single biggest benefit.

Key Features

• Hidden fit: The adapter is machined from aluminum to sit completely inside the MacBook Pro slot so there are no awkward protrusions when installed.
• High capacity support: It accepts microSD cards up to 2TB (SD specification), letting users expand their internal storage by the full card capacity.
• UHS-II and UHS-I compatible: Works with both generations of microSD cards so users can pick a faster or more affordable card to meet their needs.
• Simple installation: The adapter is easy to add and remove for most users, turning a microSD card into usable MacBook storage without complex steps.
• Time Machine support: The adapter can be used with MacBook's Time Machine backup system when a compatible card is installed.

Who It's For

This adapter is best for MacBook Pro owners who need discreet extra storage without carrying an external SSD or dongle, photographers who want to offload footage in the field, and anyone who prefers a low-profile permanent solution that fits flush with the chassis. It appeals to users who value a neat aesthetic and the convenience of inserting a microSD card as needed.

Those who should look elsewhere include users who need the fastest possible transfer speeds for heavy video editing, since real-world transfer rates depend on the chosen microSD card and some customers reported slower transfers. Also, if you expect perfect color matching to your MacBook finish, note that a slight color mismatch has been mentioned by some owners.
