Sony 256GB SF-M Tough Series UHS-II SDXC V60 Memory Card

Overview

Built for people who shoot in rough conditions, the Sony 256GB SF-M Tough Series UHS-II SDXC V60 Memory Card pairs generous 256GB storage with UHS-II speed. Reads reach 277 MB/s and writes 150 MB/s, giving raw and JPEG burst shooting plenty of headroom and getting footage onto a computer fast. A V60 rating promises never to fall below 60 MB/s while writing, which suits 4K, Full HD and 3D video.

Toughness is the other half of the story. A single moulded body shuts out water and dust, shrugs off drops and flexing, and works from -25 to 85°C, with Sony quoting up to 18 times the strength of ordinary SD cards (180N against 10N). If files go missing, the free File Rescue download can bring deleted ones back, and the SD Scan Utility warns when the card is nearing the end of its life.

Hard-Wearing Design

• IP68 sealing lets the card spend up to 72 hours in 5 m of water and keeps dust out
• Takes drops from as high as 5 m
• Resists flexing far better than the SD standard, at 18 times the bend resistance
• No connector ribs or write-protect switch to snap off
• A one-piece moulded body protects against a cracked case

Other Cameras

Although it is designed for cameras that support UHS-II and V60, the card still works elsewhere by matching the host device's class: UHS-II with V30, or UHS-I with U3, each with a 30 MB/s minimum write speed. A device that only knows U1 and Class 10 gets a 10 MB/s guarantee, while UHS-I cameras see reads up to 95 MB/s and writes up to 90 MB/s.
