Capacity & Format

The Delkin CYT microSDXC card provides 64 GB of removable storage in the microSD form factor. It suits photographers, drone pilots and mobile-device users who need high-capacity media for 4K video or large image libraries.

Speed Class & Write Rate

Class 10 rating guarantees a minimum sustained write speed of 10 MB/s, while the manufacturer specifies up to 20 MB/s typical write and 40 MB/s read. Devices that require UHS-I U1 performance will meet their minimum throughput with this card.

Thermals & Power

Solid-state construction means no moving parts and negligible heat output during normal read or write cycles. Power draw is limited to the low levels defined by the UHS-I bus, so the card adds no measurable thermal load to phones, cameras or action cams.

Questions about this item

What does the 40 MB/s read speed mean when the card is in a device?

The 40 MB/s figure is the maximum sequential read speed the card can deliver under ideal conditions; actual transfer rates will vary with the host device and file sizes.

How does the UHS-I U1 rating affect write performance?

U1 certifies a minimum sustained write speed of 10 MB/s, and the card is also rated for up to 20 MB/s maximum write on the UHS-I interface.

What size slot and adapter does this 64 GB microSDXC card need?

It fits a microSDXC slot directly; a microSD-to-SD adapter lets it work in full-size SDXC slots, but older SD or SDHC-only devices will not recognise the 64 GB capacity.
