Flash

Flash camcorders refer to two different recording media that function
in similar ways. A flash camcorder could be one that records to
removable memory cards, of which there are many. The term can also
refer to camcorders with internal flash memory.

Memory cards are small, removable cards, usually the size of a postage
stamp or smaller. Secure Digital (SD and SDHC) cards are arguably the
most popular type of card. There are also smaller versions, miniSD and
microSD, though both typically include an adapter so they fit in slots
designed for full-sized SD cards. Sony has its own line of memory
cards, Memory Stick.

Memory cards are always getting a little cheaper and a little more
capacious, much like the rest of the computer industry, so keep an eye
out for deals.

Internal flash memory, to put it simply, is like a memory card
hard-wired into the camcorder. That might sound limiting, especially
compared to a hard drive camcorder, but there are definite benefits.
Flash camcorders have no moving parts, which means less power
consumption and, because there are no moving parts in the media, better
shock resistance. It also means faster access to data when you’re
searching for certain clips.

Many camcorders now include memory expansion with a slot for memory
cards. It’s always a good idea to toss a card or two in your camera bag
before a big trip.
