64 GB SDXC card for 4K video

The SanDisk Extreme SDXC card offers 64 GB of capacity for cameras and camcorders. It supports Full HD, 3D and 4K recording as well as raw photography. The UHS-I interface and V30 speed class sustain the write rates those formats demand. A built-in write-protect switch prevents accidental erasure.

Thermals, noise and power

Solid-state memory cards have no moving parts and generate negligible heat during normal operation. They operate silently and draw minimal power from the host device. No active cooling or special power considerations are required.

Upgrade path and when it matters

This card replaces slower SDHC or lower-class SDXC media that cannot sustain 4K or high-bit-rate 3D footage. The jump is worth it when your camera requires V30 write performance or when you need 64 GB capacity for extended shoots. It does not suit devices limited to UHS-I speeds below the card's rating.

Questions about this item

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

Insert the card label-side up until it clicks; the step people miss is sliding the built-in write-protect switch to the unlocked position before first use.

What maintenance or replacement will the card need later?

No scheduled maintenance is required; replace the card if sustained write speeds drop below the 60 MB/s rating or if the 64 GB capacity becomes insufficient.

What limit appears first during sustained 4K recording?

The 60 MB/s maximum sequential write speed is the first bottleneck under continuous high-bitrate capture.
