64 GB microSDXC for everyday capture

The SanDisk Ultra microSDXC card provides 64 GB of removable storage for phones, tablets, action cameras and drones. Its UHS-I interface delivers read speeds up to 48 MB/s, letting you offload photos and Full HD video quickly. The compact form factor fits any device with a microSD slot. It suits users who need reliable capacity without premium write performance.

Thermals noise and power in normal use

As a solid-state memory card it has no moving parts, produces no audible noise and generates negligible heat during read or write operations. Power draw is limited to the host device's card slot supply, so battery impact on phones or cameras is minimal. The card operates silently and stays cool even during sustained file transfers.

Build fit and system impact

The card requires only a microSDXC-compatible slot or a standard SD adapter for larger slots. It adds no cabling, mounting hardware or driver installation to a build. Because it draws power directly from the host, it frees up USB ports and internal drive bays for other components. Buyers who need faster sustained write speeds or larger capacities for 4K recording should consider other options.

Questions about this item

How do I install the SanDisk Ultra microSDXC card, and which orientation mistake is common?

Insert the card with the gold contacts facing down and the notched corner aligned to the slot; forcing it upside down is the frequent error that bends the contact pins.

What maintenance or replacement will the 64GB UHS-I card need over time?

No scheduled maintenance is required; replace the card if read speeds drop well below the rated 48MB/s or if the host device reports write errors.

What limit appears first during sustained reads on this UHS-I card?

The 48MB/s maximum read throughput is the first bottleneck; the UHS-I bus cannot exceed that rate regardless of workload duration.
