Sure Lexar just launched a 128GB SDXC card, but that only transfers at a meager 20MB/s. SanDisk’s new Extreme Pro Compact Flash card announced today boasts the same 128GB capacity but has a write speed of up to 100MB/s. That extra 80MB/s is quite costly — unlike the $700 it costs to buy the Lexar SDXC card, this SanDisk one costs $1,500. But as they say, time is money… right?
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 has just announced that Japan’s police force has adopted its 1GB SD WORM memory card for collecting evidence. The Write Once, Read Many cards are tamperproof, can only be written to using a WORM-compatible device, and supposedly stores data reliably for 100 years. Practically speaking, this means that photographs and audio can be collected onto the cards, allowing those who access the data later on to be confident that it wasn’t tampered or edited in any way. The National Police in Japan have tested the technology extensively, and seem to be convinced of SanDisk’s claims.
We can’t really think of any practical application for ordinary photographers (can you?), but it’s interesting to know that this kind of technology is out there and being used.
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.
