128GB SDXC card for portable devices
This SanDisk SDXC card provides 128GB of storage in a full-size Secure Digital form factor. It is suited to compact portable devices that require high-capacity flash memory in a small footprint. The card uses non-volatile solid-state technology with no moving parts to help conserve battery power. It targets users of digital cameras, camcorders, smartphones and similar handheld equipment.
Sustained write performance at Class 10
The card carries a Class 10 speed rating, guaranteeing a minimum sequential write speed of 10MB/s during continuous operation. This sustained throughput supports steady recording tasks such as Full HD video capture without frame drops. Read speeds can reach up to 80MB/s for faster file transfers to a host system. The 533x rating reflects this peak read capability rather than a sustained write figure.
Check host compatibility and write protection
Verify that your device accepts SDXC cards and supports the UHS-I U1 interface before ordering. The card includes a mechanical write-protect switch on its casing that must be positioned correctly for recording. Ensure the host's card slot accommodates full-size SD media rather than microSD only. No specific speed standard beyond Class 10 and U1 is declared for this model.

It needs a standard SDXC-compatible slot that supports UHS-I and the 128GB capacity.
