The card is built to withstand water, temperature extremes, X-rays, magnets and shock.

Any device with a microSDXC slot can accept the card directly, while the supplied adapter lets it work in standard SD readers. No extra power or drivers are required. The 512GB capacity frees internal storage for system files and lets you keep large media libraries on removable media. Compatibility extends to MIL cameras that support the microSDXC format.

Questions about this item

Will the 120MB/s read speed hold up when I record Full HD video continuously?

The card is rated Class 10 and U1, guaranteeing a minimum 10MB/s sustained write speed for uninterrupted Full HD recording.

Does the card run hot or draw enough power to drain my phone battery faster during all-day use?

Memory cards have no active components, so they generate negligible heat and consume very little power during typical operation.

My phone only has a full-size SD slot — what do I need to use this microSDXC card?

The package includes a microSD-to-SD adapter so you can insert the card directly into any standard SD slot.
