Sony's newest XQD high-speed memory cards give users more options for shooting and working within 4K and file-based workflows. The new S Series of XQD cards is designed for professional 4K shooting with its ultra-fast data transfer speed of up to 180MB/s (read/write) and supports stable workflows at XAVC 4K Intra 4:2:2 (4096x2160/60p, 600Mbps). Each series includes a 32 GB and 64 GB capacity card.

The S Series features a Wear Leveling Function, Error Correction Code, Data Refresh Function and other new features to enable secure and stable recording of 4K content.

The XQD S series' fast transfer speed is achieved through the combination of a new controller, the use of high speed flash memory and a speed degradation avoiding function that promotes efficient data-writing. The new cards also support the burst mode and high definition (HD) video shooting capabilities of DSLRs.

The XQD N and S series are planned to be available in October and November, respectively, at the following retail prices:

XQD N Series - 32 GB $109; 64 GB $219
XQD S Series - 32 GB $229; 64 GB $369
