Consumers now have choices between SDXC (Extreme Capacity) and SDHC (High Capacity) cards for storing their digital images. Some cards also take advantage of UHS (Ultra High Speed) technology. Well it's June 2010 and if you want 64 GB SDXC you are going to pay from $200 to $500 for it.
Flash has become a highly profitable niche for a number of players such as Sandisk, Toshiba, and Samsung with third quarter 2009 global sales rising 26 percent over the second quarter of 2009. Incidentally, electronics research firm iSuppli noted that the average selling price of NAND flash climbed 40 percent sequentially in the third quarter.
While taking photos of big events, generally camera memory cards are used as they hold a lot of space and can easily store images from an event such as a festival or short trip. Canon's flagship SLR -- the 1Ds Mark III -- has memory slots for both SDHC and CompactFlash.
The most common type of memory card in use today is the SD card, which comes in capacities of up to 128 Gigabytes (2010). The xD Picture card was introduced in 2002 by Olympus and Fuji but it has largely been surpassed by SDHC and now SDXC.
SD Cards store up to 2GB.
SDHC Cards store from 2GB up to 32GB. Digital cameras are fine with 32GB storage, but if you are shooting high def with a camcorder then you will benefit from the new extreme capacity SDXC cards on the market.
SDXC cards store from 32GB on up to 2TB. You should look specifically for the SDXC logo. HD camcorders in particular really benefit from 2 TB of storage capacity. Canon's Rebel T2i (the 550D) camera uses SDXC flash memory.
