  • 512 GB capacity stores hours of 4K footage
  • 170 MB/s read speed offloads large files quickly

512 GB microSDXC for creators and gamers

This Silicon Power Inspire card delivers 512 GB of microSDXC storage for drones, action cameras, tablets and handheld consoles. A2 application performance and UHS-I U3 V30 ratings make it suitable for 4K Ultra HD recording and fast app loading. An SD adapter is included for broader device compatibility.

Capacity and headroom

The 512 GB capacity holds extended 4K footage and large game libraries without frequent offloading. Sequential read reaches 170 MB/s and write reaches 150 MB/s, so sustained video capture and bulk transfers stay smooth. Workloads exceeding UHS-I bus limits or requiring faster random I/O will hit the interface ceiling.

Upgrade path and when it matters

The card replaces slower Class 10 or U1 media that stutter during 4K recording or app launches. The jump is worth it when your device supports UHS-I U3 V30 and you need A2 responsiveness for gaming or multitasking. Devices limited to lower speed classes or smaller maximum capacities will not benefit fully.

Questions about this item

Will the 512GB A2 microSDXC card run at its rated speed in my older UHS-I card reader?

The card reaches up to 170MB/s read and 150MB/s write when paired with a reader that supports the DDR200 specification; older UHS-I readers will operate at their own lower limits.

How can I verify the V30 and A2 performance after installing the card?

Run a sequential write test — sustained writes at or above 30MB/s confirm the V30 rating, while A2 benchmarks should show high random IOPS for app loading.

Does the package include the SD adapter or do I need to buy it separately?

The SD adapter is included in the box; no separate purchase is required.
