The 64GB SF-UY3 Series UHS-I SDXC Memory Card from Sony features a storage capacity of 64GB and takes advantage of the UHS-I bus to support DSLR functions such as 4K and Full HD video, as well as RAW and JPEG captures. It can achieve maximum read speeds of up to 90 MB/s and maximum write speeds of up to 70 MB/s. Thanks to its U1 speed class rating, minimum write speeds are guaranteed not to drop below 10 MB/s. If your device does not support U1, this card is compatible with the Class 10 standard, which also guarantees minimum write speeds of 10 MB/s.
As with most Sony cards, this memory card is well-protected against water, dust, UV light, and static, while also being able to withstand temperatures from -13 to 185°F, allowing you to take this card with you into extreme environments, such as snow and deserts. Should the card's data become compromised, you also benefit from the option to download File Rescue software for free to help recover deleted content. Furthermore, a built-in write protect switch helps to prevent accidental deletions.
