512 GB microSDXC UHS-I U3 V30 A2 Card

This SanDisk Extreme Pro microSDXC card provides 512 GB of storage with UHS-I interface speeds. It carries U3 and V30 ratings for sustained video capture and an A2 rating for application performance. The bundled SD adapter allows use in full-size slots.

Built for 4K capture on phones.

The card suits creators who record 4K UHD video or shoot bursts of high-resolution photos on compatible mobile devices. It is not for hardware that requires UHS-II or UHS-III bus speeds. It is not for workflows that need sustained write performance beyond the stated 90 MB/s.

170 MB/s read and 90 MB/s write speeds

Sequential read reaches 170 MB/s and sequential write reaches 90 MB/s, enabling transfer of 1000 photos and 24 GB of 4K footage in roughly 3 minutes. These figures determine whether the card matches your device's required throughput.

Soalan tentang produk ini

Does the 90 MB/s write speed generate noticeable heat during long 4K recording sessions?

The card is rated for sustained 90 MB/s writes and carries the V30 video speed class, which is designed for continuous 4K UHD capture without thermal throttling under normal use.

My device only has a full-size SD slot — will the bundled adapter let me use this microSDXC card directly?

Yes, the package includes a microSD-to-SD adapter so the 512 GB card works in any standard SDXC slot that supports UHS-I speeds.

Will the A2 rating actually speed up apps on a phone that is three years old?

A2 performance requires host support for command queuing and caching; older phones without that support will still run apps, but they will not see the full A2 benefit.
