64GB microSDXC UHS-I Card

This SanDisk Ultra microSDXC card provides 64GB of removable storage for Android smartphones and tablets. It carries UHS-I, U1, Class 10 and A1 ratings for app performance. Maximum read speed reaches 120MB/s for fast file transfers. The card is sold without an SD adapter.

Who this suits and who it does not

Ideal for users expanding phone or tablet storage for photos, Full HD video and apps. The A1 rating helps launch apps quickly from the card. Buyers needing sustained write speeds for 4K recording should consider a card with a higher video speed class. Devices limited to the original microSD format cannot use this 64GB XC capacity.

UHS-I U1 Class 10 A1 specification

The UHS-I bus with U1 and Class 10 ratings guarantees a minimum write speed of 10MB/s. A1 certification adds random read and write performance for Android apps. These combined ratings determine whether the card meets your device's speed requirements. No adapter is included in the package.

Questions about this item

Does my phone need a microSDXC slot to use this 64GB card?

Yes, the host device must support microSDXC; older slots limited to microSDHC (32GB maximum) will not recognise this 64GB capacity.

Will the U1 speed class sustain Full HD recording on an older camera that only requires Class 10?

The card meets both U1 and Class 10 minimums, so it will maintain the required write speed for Full HD on legacy cameras.

How can I confirm the 120MB/s read speed after inserting the card?

Run a benchmark tool such as CrystalDiskMark on a UHS-I reader; sequential read results should approach 120MB/s.
