JVC Everio GZ-MG555 - CNET
CNET have published a review of the JVC Everio GZ-MG555 which records video to an onboard hard drive. 'Like all Everio camcorders, the GZ-MG555 records video to an onboard hard drive, rather than tapes or DVDs. The 30GB drive holds up to 37 hours of video, though that's only when shooting at the lowest quality setting. Most users will probably shoot at the Fine and Ultra Fine quality settings instead, at which the hard drive can respectively hold 10.5 and 7 hours of footage. If that's not enough storage for you, the camcorder also features an SDHC card slot so you can record both video and still photos onto flash memory. Since 4GB SDHC cards can be found for about $50, they present an inexpensive, convenient way to grab just a little more recording time.
