Sony is expanding its lineup of memory card options for professionals to include newer and faster XQD and SD media, as well as card readers for the XQD and SD formats, and an XQD USB adapter, all designed to support the latest high-performance DSLR cameras like Nikon D5 or D500.

Sony’s XQD-M series provides users ultra-high data transfer speeds of up to 440MB/s (read) and 150MB/s (write) for stable burst shooting, and the ability to backup 64GB of data in approximately 3 minutes, when using Sony’s newest card reader technology. The XQD format’s unique and robust structure, featuring card thickness and pin protection, and a tough, reinforced outer case is made for reliable use.

Both new media offerings are extremely dependable and durable, dust-proof, X-Ray proof, anti-static and magnet proof to protect the most sensitive photo and video content. Downloadable File Rescue Software aids in the recovery of photos and videos that may have been deleted, including RAW images, MOV files and 4K XAVC-S video files.

Whoa, that's a WAY better price, less than half that of the previous models
