512 GB microSDXC UHS-I card

This SanDisk Extreme PRO microSDXC card provides 512 GB of storage for cameras, drones and mobile devices. It uses the UHS-I interface and carries a Class 10 speed rating for sustained write performance. The card targets creators who need high-capacity removable media.

Thermals noise and power

Solid-state memory cards generate negligible heat and operate silently during read and write cycles. Power draw is minimal and scales with the host device's UHS-I bus activity. No active cooling or special thermal management is required.

200 MB/s maximum read speed

The quoted 200 MB/s read speed is the headline transfer rate that determines how quickly large files can be offloaded to a computer. Write speeds are lower and vary with the host device and workload. Buyers who need guaranteed minimum write speeds for professional video codecs should verify the card meets their specific sustained-write requirements.

Questions about this item

How do I install the SanDisk Extreme PRO 512GB microSDXC card and what step do people often get wrong?

Insert the card into a microSDXC UHS-I slot until it clicks; the common mistake is using a device that only supports microSDHC, which cannot address the 512 GB capacity.

What maintenance or replacement will this card need over time?

No scheduled maintenance is required; replace the card if write errors appear or after heavy write cycles exhaust the NAND endurance.

What limit appears first during sustained use of the 200 MB/s read speed?

The UHS-I bus caps continuous throughput, so sustained transfers will settle at the interface maximum rather than the peak 200 MB/s figure.
