Capacity & Class

The Delkin SDXC card provides 256GB of storage in a full-size Secure Digital form factor. It carries a Class 10 speed rating and UHS-I U3 specification for sustained write performance. The card is suited for cameras, camcorders and other portable devices that require high-capacity removable media. It is not intended for buyers who need internal solid-state storage or larger capacities than 256GB.

Interface & Compatibility

The card uses the standard SD interface and fits any device with a full-size SDXC slot. No extra adapters or power cables are required for operation. The mechanical write-protect switch on the casing lets you prevent accidental data loss. Builders who need a microSD form factor or a different bus interface cannot use this card directly.

Rated read speed reaches 95MB/s and write speed reaches 80MB/s under the 633x rating. Solid-state construction with no moving parts helps conserve battery life in portable devices. The card weighs approximately two grams and operates silently. Users who require faster sustained throughput for professional video workflows should verify their device supports the necessary bus mode.
