"iVDR is another storage format unlikely to get outside of Japan, which reminds me of Iomega's Jaz series. But the capacities are much better -- we go up to 80GB this time. Though there are three possible sizes of iVDR, these discs are 80 x 110 x 12.7mm, or about 3" wide and 4.3" tall. IO Data Device Corporation will release 40GB and 80GB iVDR standard media, as well as a USB 2.0 iVDR adapter, in late January. The price of the 40GB "iVDR-H40" media is 20,790 yen, the 80GB "iVDR-H80" media 31,290 yen, and the "USB2-iVDR" supporting adapter 10,290 yen...The equipment complies with standards set forth by the iVDR Hard Drive Consortium, and is usable as a removable disc by the PC. The media body uses reinforced plastic, and is rated for up to 900G of shock impact when not operating."Cool concept, but we'll probably never see it here. I use a portable 2.5" 40 GB hard drive as a second level backup, but something like this would make it easier for me to do rotating data backups. I'm a big fan of external drives - how about you?
