Toshiba has announced its new family of 1.8" hard drives which are 10% smaller than its first generation perpendicular magnetic recording (PMR) HDD's.

The two new models introduced - the 40GB MK4009GAL and 80GB MK8009GAH - are both 4200RPM units which feature an areal density of 134 gigabits per square inch. Given their reduced footprint, the 40GB and 80GB drives now measure 54x71x5mm and 54x71x8mm respectively and weigh in at 48 grams and 59 grams respectively. The cache size was also increased to 8MB.
