Toshiba has today launched four new 1.8in hard drives designed for use in portable media devices. The MK1634GAL family, available in 60GB, 80GB, 120GB and 160GB capacities, weighs less than 48 grams and measures approximately 5mm thick.
Toshiba's largest model is the industry's first to offer 160GB of storage on a single-platter 1.8in drive. The result is an areal density of up to 467 gigabits-per-square-inch. According to Toshiba, it'll keep noise levels at 14 decibels when idle and only 15 decibels when in operation, making it ideal for handheld devices.
All four drives are shipping now, and the largest 160GB model explains how Apple managed to yesterday up the maximum capacity of its revised iPod classic.
Each drive's complete specification, as detailed by Toshiba, is provided below.
