SDメモリーカード
Until 2010, Sony insisted on usage of its own memory card format - Memory Stick. Since 2010, Sony has allowed using both Memory Stick as well as Secure Digital cards in its consumer and professional camcorders. Panasonic as well as other manufacturers of AVCHD camcorders use Secure Digital cards as removable flash media. Most models accept Secure Digital High Capacity cards (SDHC), while some models are also compatible with Secure Digital Extended Capacity (SDXC) cards, which offer higher transfer speed and capacity.
