For weeks, I’ve been putting the Extreme PRO SDHC And SDXC UHS-I Card Memory Card 64.0 GB (SDSDXXU-064G-GN4IN) through its paces. From shooting high-resolution stills in rapid burst mode to recording extended 4K video footage, I’ve pushed this card to its limits to see if it lives up to its “Extreme PRO” name. This in-depth review will cover its performance, durability, and overall user experience.

The Extreme PRO SDHC And SDXC UHS-I Card boasts impressive specifications. It’s designed for professionals and serious enthusiasts who demand high-speed performance and reliable storage. Key features include its UHS-I interface for fast data transfer speeds, its compatibility with 4K UHD video recording, and its robust build designed to withstand the rigors of daily use. The promise of data recovery is also a significant selling point for those who have accidentally deleted precious files.

My testing involved several scenarios: shooting RAW images in burst mode with my high-end DSLR, recording 4K video footage, and transferring large amounts of data to my computer. The write speeds were consistently impressive, minimizing buffer clearing time during burst shooting and allowing for seamless 4K video recording without dropped frames. Read speeds were equally fast, making post-production workflows significantly smoother. I was particularly pleased with how well it handled prolonged recording sessions, maintaining consistent performance throughout. The data recovery feature, while I didn’t need to actively use it during the review, is a reassuring bonus.

While the card performed exceptionally well in most tests, I did notice a slight performance dip under extreme heat. This was during an extended outdoor video shoot on a particularly hot day. While not a significant concern for typical usage, it’s something to keep in mind for professional users working in challenging environments. However, even under these stressful conditions, it did not fail or lose any data.

Pros:

• High read and write speeds
• Excellent performance with 4K video
• Reliable and durable build
• Data recovery software provides peace of mind
• Great value for the storage capacity

Cons:

• Slight performance degradation under extreme heat
• Price might be slightly higher than some competing cards

Overall, the Extreme PRO SDHC And SDXC UHS-I Card (SDSDXXU-064G-GN4IN) is a high-performing memory card that delivers on its promises. While the slight heat sensitivity is a minor drawback, the speed, reliability, and included data recovery features make it a worthwhile investment for both professional and enthusiast photographers and videographers. I highly recommend it for anyone needing reliable and high-speed storage for their demanding projects.
