256GB microSDXC for Android devices

The SanDisk Ultra microSDXC card provides 256GB of removable storage for Android smartphones and tablets. It carries A1, UHS-I U1 and Class 10 ratings with a maximum read speed of 100MB/s. A full-size SD adapter is included for use in card readers or cameras. The card is sold new in retail packaging.

Who this suits and who should look elsewhere

This card suits users who need extra space for apps, photos and Full HD video on Android phones or tablets. The A1 rating helps apps launch and run more smoothly from the card. Buyers who require sustained write speeds above 10MB/s for 4K video or professional workflows should consider a higher-specification card.

Deciding specification: A1 application performance

The A1 rating guarantees minimum random read and write IOPS for faster app loading on Android devices. Combined with U1 and Class 10 it also supports Full HD video capture. If your device or workflow does not need A1 app performance, a lower-cost card without that rating may be sufficient.

Questions about this item

Does the card come with an SD adapter or do I need to buy one separately?

The package includes a microSDXC-to-SD adapter so the card can be used in full-size SD slots without an extra purchase.

Which speed class should I choose for recording Full HD video on an Android phone?

The UHS Speed Class U1 and Speed Class 10 ratings guarantee the minimum sustained write speed needed for Full HD video recording and playback.

What does the "up to 100MB/s" read speed mean when the card is in my phone?

It is the maximum sequential read rate under ideal conditions; real-world app loading and file transfers will typically be lower depending on the device and workload.
