Did you know that...
... SD [secure digital] memory cards are limited to a maximum capacity of 2GB? That's why a new standard had to be developed to extend the memory capacity -- called SD-HD [high density]. Initially you'll see 4GB SD-HD cards, but 32GB SD-HD cards are being promised. Warning! These new cards do not work with your digital cameras and other SD devices. They only work with new hardware built to the new specification.
...memory cards from Sony were even worse off. The initial spec allowed a max of 128MB. Sony has since had to twice re-engineer their MemoryStick cards to handle the boom in increased memory card size. Talk about short-sighted! I continue to use CompactFlash cards, which don't suffer from these limitations.
...the PNY and Dane-Elec brands are owned by Toshiba? Using different branding allowed the Japanese company to sell memory at lower prices without undercutting the Toshiba name.
