If you can fit more data onto a notebook hard drive, more power to you. Per PC World, hard drive manufacturer Seagate seems ready to launch a 7 millimeter high notebook drive as part of its Momentus lineup this January at CES.

Although Seagate has yet to release specifics, it’s thought that the drive will be spinning a single platter. Given that dual-platter 2.5″ disks currently max out at 640GB (or 320GB per platter), Seagate is expected to at least match this or even demonstrate an improvement in the amount of data that can be placed on each platter.

It’s anyone’s guess, but it’s cool stuff and we’ll be following this up until its release.
