Toshiba today announced 80 (single platter) and 120 GB (dual platter) 1.8" hard disk drives that use the Serial ATA (SATA) interface and operate at 5400 RPM.
Currently, Apple's MacBook Air and iPod Classic utilize 80 GB single platter 1.8" hard drives running at 4200 RPM over a Parallel ATA (PATA), though the Air has a solid state drive option. By incorporating the SATA bus and increasing the rotational speed, the performance should elevate to that of standard 2.5" drives used in larger laptops such as Apple's MacBook or MacBook Pro.
