Sonic Pro Plus microSDXC 256 GB

The Samsung Sonic Pro Plus microSDXC card provides 256 GB of storage with UHS-I Class 10 performance. Sequential read speed reaches 180 MB/s while write speed reaches 130 MB/s. An SD adapter is included for use in full-size slots. The card carries a yellow Sonic-themed design.

Suits gamers and creators needing fast portable

This card targets console owners, smartphone users, camera operators and tablet owners who want quick load times and lag-free gaming. The 256 GB capacity may not satisfy buyers who want more storage for large media libraries. Users requiring UHS-II or V90 write speeds should look at something else.

UHS-I Class 10 with 180 MB/s read speed

The single specification that decides fit is the UHS-I Class 10 interface delivering up to 180 MB/s read and 130 MB/s write. This determines whether the card meets the minimum speed requirement of your console, camera or mobile device. No other speed class or interface is supported by this model.

Questions about this item

Does my device need a microSDXC slot that supports UHS-I and Class 10 to use this card?

Yes — the card is a microSDXC UHS-I Class 10 device, so the host must accept that format and speed class for full 180 MB/s read and 130 MB/s write performance.

Will the included SD adapter let me read the card in an older laptop that only has a full-size SD slot?

The bundled adapter converts the microSDXC card to standard SD dimensions, allowing it to work in any full-size SD slot that supports SDXC capacity and UHS-I speeds.

How can I verify the card is delivering its rated 180 MB/s read speed after I install it?

Run a sequential-read benchmark such as CrystalDiskMark or Blackmagic Disk Speed Test on the mounted volume; a result near 180 MB/s confirms the card and host are operating at spec.
