CNET has not reviewed the JVC Everio GZ-MG630. However, it is primarily the same as the JVC Everio GZ-MS120, which has been reviewed.
The only differences between the two models are size and storage media. The slightly smaller MS120 has no fixed internal memory. Instead, it has two SD/SDHC memory card slots, but no included memory cards. Buyers must purchase an SD/SDHC card up to 32GB separately.
The JVC Everio GZ-MG630 has an internal 60GB hard drive for storage as well as a microSDHC card slot for expansion.
