The built-in write-protect switch adds extra security by preventing accidental data loss. The card does not come with a reader, so you’ll need a compatible SDXC reader to connect it to your computer.

Its UHS-II interface ensures quick data transfer, making it suitable for professional photographers and videographers who demand speed.

Beyond speed, this card stands out in durability.

Sony is a trusted brand in memory products, and the card comes with data recovery software, which can be helpful if files are accidentally lost.

While it’s fast and durable, the price is usually higher than standard SD cards, which might not be necessary for casual users. Also, to get the full speed benefit, your camera or device must support UHS-II; otherwise, speeds will be limited. This card suits users who need top speed and rugged durability in demanding environments, although casual photographers may not require all its features or associated cost.

It is also waterproof (IPX8) and dustproof (IP6X), ensuring reliable performance in harsh conditions.

Sony’s reputation in the electronics industry is strong. However, users should note that while it’s backward compatible with UHS-I devices, the highest performance is achieved only with UHS-II compatible cameras. This may limit its utility for some older devices. Moreover, despite its rugged construction, the cost might be higher compared to other standard SD cards. This card is best suited for professionals and enthusiasts who prioritize speed, durability, and reliability in demanding environments.
