Capacity and interface

This SanDisk Extreme PRO microSDXC card provides 512 GB of removable storage in the UHS-I format. It is built for devices that accept microSDXC media and need sustained write performance for continuous recording.

Who this suits and who it does not

The Class 10 rating and 200 MB/s read speed support 4K video capture and fast file offloads for photographers and drone operators. Buyers whose host device only supports the older microSDHC standard or requires a Video Speed Class rating beyond Class 10 should look at a different specification.

Deciding specification

The 512 GB capacity combined with the microSDXC UHS-I format determines whether the card will be recognised and deliver its rated throughput in a specific camera, action cam or laptop slot.

Questions about this item

Will the microSDXC 512 GB card fit my device's microSD slot?

Yes, the card uses the standard microSDXC UHS-I form factor that fits any microSDXC, microSDHC or microSD slot.

What is the correct way to insert the card so the contacts seat properly?

Hold the card with the label facing up and the gold contacts toward the slot, then push gently until it clicks; forcing it upside-down bends the contacts.

When should I replace the card to avoid data loss from wear?

Replace it if write speeds drop noticeably, files become corrupted, or the card fails to mount — typical endurance lasts years of daily 512 GB cycling.
