The image shows a close-up of an authentic SanDisk Extreme PRO SDXC memory card with a capacity of 256 GB. The black body of the card clearly displays its key technical specifications: a stated read speed of up to 200 MB/s, UHS Speed Class 3 (U3), and Video Speed Class V30, making it suitable for 4K UHD video recording. The card features a standard mechanical write-protect switch on the left edge and the signature red-and-white SanDisk logo at the bottom.
