Is the UHS-II SD Memory Card Reader compatible with UHS-I and standard SD cards?
Yes. While it is designed for UHS-II SD cards like Sony's SF-G and SF-M series, it is backward compatible with UHS-I and standard SD, SDHC, and SDXC cards. You will only reach UHS-II speeds when using UHS-II cards.
What connection does the UHS-II SD Memory Card Reader use?
It uses a SuperSpeed USB (USB 3.1 Gen 1) Type-A connector for fast data transfer to your computer. It is also backward compatible with USB 2.0, though at reduced speed.
Which operating systems are supported?
The reader is compatible with Windows 7 (SP1), Windows 8.1, Windows 10, and macOS 10.9 or later, working as a standard USB mass-storage device.
Is this reader good for transferring 4K video and large RAW photo files?
Yes. It is optimized to get the most from UHS-II SD cards' speed performance, saving transfer time when backing up large photo libraries or 4K video so you can return to editing faster.
Does the reader work with microSD cards?
It has a single standard SD card slot for SD, SDHC, and SDXC cards only. MicroSD cards would require an adapter, as there is no dedicated microSD slot.
Is the UHS-II SD Memory Card Reader suitable for travel?
Yes. It features an ultra-compact, lightweight housing measuring approximately 57 × 31 × 11 mm and weighing about 20 g, making it easy to carry in a bag or pocket. A removable snap-on cap protects the USB connector during transport.
Which Sony cards work best with this reader?
Sony recommends the reader for its SF-G and SF-M series UHS-II SD cards, allowing these cards to perform near their maximum read speeds for the fastest possible file transfers.
What warranty comes with the UHS-II SD Memory Card Reader?
The reader comes with a 1-year warranty. You can also access manuals, firmware, and support directly through Sony's product support pages.
How much does the UHS-II SD Memory Card Reader cost?
