The new Sony cards are based on the XQD memory card specification, which the CompactFlash Association recently approved and licensed as an open format.
According to Sony, the new XQD memory card achieves stable continuous shooting of RAW images and blazing fast data transfer rates of up to 1Gbps/125MB/s write and read (based on Sony tests and dependent on host hardware) through the PCIe interface, a computer expansion card standard for serial interfaces.
A new controller and optimized flash memory enables high-speed data processing, resulting in faster write speed and performance that can't be achieved by conventional compact flash cards.
Sony is also introducing a USB 2.0/3.0 compatible XQD card reader (model MRW-E80) so users can easily transfer large quantities of very high capacity data to their PC. Also, an XQD ExpressCard Adapter (QDA-EX1) will be available for use with computers with an ExpressCard 34 card slot.
The new Sony products are planned to be available in February and are estimated to sell at the following retail prices:
QD-H16 card, 16 GB, $129.99
QD-H32 card, 32 GB, $229.99
Card Reader, MRW-E80, $44.99
ExpressCard Adapter, QDA-EX1, $44.99
