Nikon, Sony, and Sandisk have announced that they’re teaming up to develop a set of specifications for the next generation of memory cards. The new format uses a new interface (PCI Express, previously Parallel ATA) that allows data transfer rates of up to 500MB per second. The theoretical maximum capacities of the cards would also be increased from the current 2 terabyte ceiling.
These future cards would allow photographers with future cameras to store a large number of RAW images captured with continuous burst shooting, and would also make transferring data off the card a snap. No word yet on when the future will arrive.

SanDisk just released its 64GB Ultra SDXC (extended capacity) memory card, the largest capacity for the Secure Digital format. It has a read speed of up to 15MB/second, stores up to eight hours of high-definition video, and costs $350. The new card uses the SD 3.0 specification, which allows capacities up to 2TB (2000GB).
It just so happens that today the CompactFlash Association also announced the CF5.0 specification, which allows memory cards up to 144PB (petabytes), or 150,994,944GB. Oh boy.
Sadly, the new Compact Flash specification only affords transfer speeds up to 32MB/s, meaning a full 144PB card would take about 153 years to transfer.
