2.5 TB as the Next Step for 3.5" HD?

Currently 3.5" HDs offer up to 2 TB of storage space. They are composed of 4 discs of 500 GB each. If in theory 5 discs could fit in the enclosure, to reach 2.5 TB, no manufacturer made this choice so far. Indeed, with the heat released by mechanical operations, it would impact reliability and life time. However, we should see 2.5 TB HD models soon according to a roadmap from TDK, one of the main manufacturers of HD heads. They have in development a head able to push capacity of each disc to 640 GB. Once ,assembled by four of such disc, it would storage space of 2.5 TB. For 2.5" HD, their storage capacity could reach 750 to 800 GB splitted on 2 discs.
