The notebooks of tomorrow will feature more storage than ever before, so long as companies like Toshiba continue to push the areal density and capacity envelopes of 2.5-inch drives. Such is the case today, as Toshiba announced two new 2.5-inch HDDs: MK7559GSXP (750GB) and MK1059GSM (1TB).
Toshiba says its MK7559GSXP is the industry's highest areal density and capacity drive, which crams 750GB into a standard 9.5mm high, two-platter design. It's also easy on the environment, consuming 14 percent less energy than the previous generation MK6465GSX (640GB) drive.
The 1TB drives sports a three-platter, 12.5mm high design with 6 heads. It consumes a bit more power than the 750GB at 2.2W (seek) and 1.7W (read/write), compared to 1.85W and 1.5W, respectively. But like the other drive, the 1TB model sports a 12ms seek time, SATA II interface, 8MB of cache, and spins at 5400RPM.
No word yet on price or availability.

I was really tempted to get the 1TB Western Digital Passport 2.5" portable HDD. It's a dream come true.

I don't know about areal density, but you can buy 12.5mm 1tb 2.5" drives from Western Digital already at Newegg. I think they came out a few months ago. Now somebody just needs to release a 9.5mm 1tb drive.
