Capacity and use-case

The Silicon Power Superior Pro is a 64 GB microSDXC card rated UHS-I U3 and Class 10. It targets users shooting 4K or 1080p video on action cameras, drones or smartphones that need a minimum 30 MB/s sustained write speed. The card also works in DSLRs and camcorders via the supplied SD adapter.

Bundled adapter

An SD adapter is included in the package. It lets you use the microSDXC card in full-size SD slots found on many cameras and card readers. The adapter adds no extra speed; the card still delivers up to 90 MB/s read and up to 80 MB/s write when the host supports UHS-I.

Compatibility check

Verify that your device accepts microSDXC cards and supports UHS-I to reach the rated speeds. A UHS-I capable reader with USB 3.0 is needed for maximum transfer rates. The card is not suitable for hardware limited to microSDHC or non-UHS hosts.

Questions about this item

Will the write speed stay above 30 MB/s when I record 4K video for long periods?

The U3 rating guarantees a minimum sustained write speed of 30 MB/s, which is the figure the card is designed to maintain during continuous 4K recording.

What is the first limit I hit when writing large files continuously?

The sequential write speed tops out at 80 MB/s, so that ceiling appears before any other bottleneck during sustained transfers.

Does the card run hot or draw extra power during all-day time-lapse shoots?

The card is a passive microSDXC device with no moving parts; it generates negligible heat and draws only the standard low power defined by the UHS-I interface.
