Hitachi is working on packing an insanely large amount of storage into an incredibly tiny space by way of their iVDR technology. We speak with Hitatchi about iVDR in this clip, where they mention squeezing 760 GB into a 2.5-inch sized drive. iVDR is expected to launch in April over in Japan, and a 160 GB module will likely cost around $300 USD. We get a look at a couple of prototype ideas as well, all in this clip.
