Capacity and use case

The SanDisk Ultra microSDXC card provides 256 GB of storage for Android smartphones and tablets. It records Full HD video and stores large photo libraries without running out of space. The A1 rating helps apps launch faster on mobile devices.

Speed class and transfer benefit

Class 10 and UHS-I ratings guarantee a minimum sequential write speed for smooth Full HD capture. Read speeds reach up to 100 MB/s, letting you offload up to 1200 photos in a minute. Faster transfers reduce waiting time when moving files to a computer.

Installation notes

Insert the card into the device's microSD slot until it clicks; most phones and tablets recognise it instantly. If the device formats the card as internal storage, it cannot be read elsewhere without reformatting. Handle the small form factor carefully to avoid bending the contacts.

商品問答

How many write cycles can the 256 GB Ultra A1 microSDXC card sustain before cells wear out?

SanDisk does not publish a TBW or cycle rating for this Ultra A1 card, so a precise endurance figure is not available.

What is the minimum sustained write speed the Class 10 rating guarantees during long recordings?

Class 10 certifies a minimum sequential write speed of 10 MB/s, which is the floor for continuous Full HD capture.

Does the card run hot or draw extra power when transferring at the 100 MB/s read peak all day?

The microSDXC UHS-I interface limits bus power to a few hundred milliwatts, so the card stays cool and draws minimal current even at peak read throughput.
