Overview
This is a passive plastic adapter that lets a microSD card plug into any standard SD card slot, such as a laptop reader, DSLR camera or card reader. It carries no memory of its own and simply extends the physical connector, with a sliding switch on the side to mark the card read-only.
SanDisk sells this mostly as a companion to its own microSD lines, but it works with any brand of microSD or microSDHC card. The write protection switch is a physical lock, not a software one, so it only helps if the host device actually checks it. At 1.25 x 0.9 x 0.1 inches it slides into a wallet slot or camera bag pocket without adding bulk.

- Works with any brand of microSD card
Who it's for
Anyone who bought a microSD card for a phone or action camera and now needs it to work in a laptop, camera or reader that only takes full-size SD. It also suits a second household adapter as a backup for when the one that shipped with a card gets lost.
Strengths and trade-offs
Drawn from this product's published specifications.
- Fits any microSD or microSDHC card into a full-size SD slot
- Physical write protection switch
- Small enough to carry as a spare
- Adds no storage or speed of its own
- Write protection only works if the host device honors it
Performance notes
There is no electronics inside; the adapter is a set of contact pins wired straight through to the card underneath, so read and write speeds are set by the microSD card, not by the adapter. The write protection switch physically holds a tab that many card readers check before allowing writes, similar to the lock switch on an older SD card.
