64 GB SDXC card for 4K video and burst photography

The SanDisk Extreme PRO is a 64 GB SDXC card built for cameras that record Full HD, 3D and 4K video or shoot raw and burst stills. It uses the UHS-I bus and carries both V30 and U3 speed ratings, guaranteeing a minimum sustained write speed of 30 MB/s. Maximum read speed reaches 170 MB/s and maximum write speed reaches 90 MB/s. A built-in write-protect switch helps prevent accidental data loss.

Thermals, noise and power in normal use

As a solid-state memory card it has no moving parts, produces no audible noise and draws negligible power from the host device. The card is rated to operate from -13 °F to 185 °F, so it remains reliable in desert heat, freezing snow or humid poolside conditions. X-ray proof, shockproof and waterproof construction adds further protection during travel and outdoor shoots.

Upgrade path and when the jump matters

This card replaces slower SDHC or early SDXC cards that cannot sustain 30 MB/s write speeds, removing the bottleneck that causes dropped frames or paused bursts. The step up is worth it when your camera supports UHS-I, V30 or U3 and you regularly shoot 4K video or high-resolution raw sequences. It will not benefit devices limited to lower speed classes, as the card simply defaults to the host’s maximum capability.

Questions about this item

How do I install the SanDisk Extreme PRO 64GB card and what step is often missed?

Insert the card into your device's SDXC slot with the label facing up until it clicks; the step people miss is sliding the built-in write-protect switch to the unlocked position before first use, otherwise the camera cannot record.

What maintenance or replacement will the 64GB Extreme PRO card need later?

No scheduled maintenance is required; the card is X-ray proof, shockproof, waterproof and rated for -13 to 185°F, so replacement is only needed if physical damage occurs or capacity becomes insufficient.

What limit appears first during sustained 4K recording on this V30 card?

The V30 and U3 ratings guarantee a minimum write speed of 30 MB/s; if your camera's bitrate exceeds that sustained threshold, recording will stop or drop frames before the 90 MB/s peak write speed is reached.
