XQD Compact Flash

Compact flash is a removable mass storage device format used mostly in portable devices. It is a competing format to the more popular SD card format. The Compact Flash Association has adopted the new XQD format that is smaller than previous formats but still thicker than an SD card. XQD uses the PCI Express interface and is expected to have real world write speeds of 125 Mbps. The format is scalable and future cards can be faster, one of the driving forces of this new format. Some notes from their press release

The key features of the XQD format include:

Optimized form-factor
* Dimensions : 38.5 x 29.8 x 3.8mm
* Durable & Robust

Scalable High Performance Interface
* PCI Express: 2.5Gbps today and 5Gbps Future

Actual Write Speeds
* Target 125MB/sec and Higher

XQD cards will be shown at the CompactFlash Association booth at CP+ 2012, February 9-12 in Yokohama, Japan. Licensing for CFA members will start in early 2012.

My preference is the SD card format because that is what my devices support. I like interoperability. I dislike the proprietary formats and less popular formats. What's your opinion on this new CF format? Share with us in the comments below.
