Our partner Designtechnica reviewed the JVC GZ-MG70U digital camcorder with 30GB hard-drive.

JVC introduced the GZ-MG camcorders in June.

Quote from the JVC GZ-MG70U review:
"Hard disk drives are taking over the world! At one time, HDDs were safely ensconced in PCs and laptops. Then they moved to outboard drives, satellite and cable boxes, combination DVD/HDD recorders, iPod digital audio players…the list goes on.
Now the engineers at JVC have created a series of Everio ultra-small, super lightweight camcorders with built-in 20GB or 30GB drives that record up to seven hours of MPEG2 video.

This is many times the capability of wildly popular DVD camcorders like the Sony DCR-DVD203 that record 20 minutes of best-quality video on single-sided 3-inch 1.4GB disks. And in keeping with the trend of combining digital still cameras and camcorders, the new GZ-MG70U has a 2.12MP CCD so it takes 1600 x 1200 pixel stills. It's not the 12-megapixel Canon EOS 5D but it can satisfy your need for a photograph or 10,000."
