SanDisk 64 GB SDXC Ultra Card

This SanDisk SDXC Ultra card provides 64 GB of storage for cameras and other devices that accept the SDXC format. It carries a UHS Speed Class 10 rating and a 320X speed designation. The manufacturer lists a maximum read speed of 48 MB/s. It was first listed by the manufacturer in 2019.

Suits photographers needing basic capacity

The card suits photographers who need a straightforward 64 GB card for everyday shooting. It is not for users who require faster write speeds for continuous burst photography or high-bitrate video recording. Buyers who need more storage capacity should look at higher-capacity cards.

Simple drop-in installation

Installation is a simple matter of inserting the card into a compatible SDXC slot until it clicks. What usually goes wrong is using the card in a device that only supports the older SDHC standard, which cannot address 64 GB. Another common issue is a write-protected switch left in the lock position.

Questions about this item

What device slot is required to use this 64 GB SDXC card?

The card fits any SDXC-compatible slot in cameras, laptops or card readers that accept the SDXC form factor.

Will this UHS Speed Class 10 card work in an older camera that only supports standard SDHC?

The card is SDXC, so it requires an SDXC-capable host; an SDHC-only device will not recognise the 64 GB capacity.

How can I verify the card delivers the rated 48 MB/s transfer speed after first use?

Run a sequential-read benchmark such as CrystalDiskMark or Blackmagic Disk Speed Test and confirm sustained reads near 48 MB/s.
