Overview
A camera bag on a shoot day is where this SDXC card earns its place. It stores photos and ultra high definition video from cameras that accept full-size SD media, and the QuickFlow feature speeds offloading through a compatible reader.
Sustained write ratings suit ultra high definition recording, and the quoted read speed shortens the wait when copying files to a computer. Peak speeds are tied to compatible hardware, and the reader that reaches them is sold separately.
Who it's for
A shooter who offloads large video files and wants a rated sustained write speed in the card. A camera user with a basic reader will not see the headline read speed. Phone and action camera owners need a different card format.
Pros and cons
- High sustained write rating for video
- QuickFlow offload with compatible reader
- Rated for water, shock and X-rays
- Lifetime limited warranty
- Peak read needs a separate reader
- Full-size SD format only
- Speeds depend on the host device
- Dimensions suit standard slots only
Performance notes
Real transfer speed is set by the weakest link: the card, the host device and the reader. The headline read figure goes beyond the normal UHS-I limit through the proprietary QuickFlow feature, and only compatible readers can use it. Write speed is rated for continuous video capture on devices that support the UHS standard.

Frequently asked questions
Is the SanDisk Extreme PRO 64GB a microSD card?
No. It is a full-size SDXC card with a listed size of 1.26 by 0.94 inches, so a device with only a microSD slot will not take it.
Do I need a special reader for the 200 MB/s read speed?
Yes. The description says the top speed needs compatible devices and pairs it with the SanDisk Professional PRO-READER SD and microSD, sold separately.
Can the SanDisk Extreme PRO record 4K video?
The listing says UHS Speed Class 3 and V30 support 4K UHD recording, though it adds that support may vary by host device.
How long is the warranty on this SanDisk card?
A lifetime limited manufacturer warranty is listed.
