 SDXC memory cards : Last year, the specifications of a new generation of Secure Digital flash (SD) memory cards were made public. And these were, to put it lightly, impressive. With SD as base and SDHC (SD High Capacity) for higher storage capacities of a maximum of 32GB, a heavy specification requirement was set for every new type of card that would take over after SDHC. However, anyone taking a look at the SDXH (Secure Digital eXtended Capacity) roadmap, and sees a storage capacity of 2TB and a bus interface speed of 104MB/sec to 300MB/sec in a later phase, will soon be convinced. Panasonic starts off this year with the introduction of the first 48GB and 64GB SDXC memory cards.

2TB SDXC memory cards
During our visit to the CES 2010 show in Las Vegas, we talked to one of the employees of the SD Association, during which became obvious that we can expect an increase in storage capacity each year for the coming years, with a maximum of 2TB. In practice, this will mean that a 2TB SDXC memory card will be introduced around 2015, so we still have a bit to go. To get an idea: about 100 High Definition films or 480 hours of High Definition video, or 136,000 high-resolution photos fit onto a 2TB SDXC card.
Panasonic 64GB SDXC memory card
The first SDXC memory cards are thus a fact; we just need to wait for a wide assortment of devices. Canon and Panasonic introduced several new compact cameras with SDXC support during the CES show, but we will still have to wait for the DSLR manufacturers such as Canon and Nikon. Especially professional digital SLR cameras are exceptionally suitable to work with SDXC cards. Speed, high resolution and storage capacity are features that the professional photographer goes for. And thereby, in terms of price, it all fits better in this segment, as the Panasonic 64GB SDXC has a price tag of $599.95 / Euro 499.
