Toshiba launches 1.8in 160GB hard drive

Increased storage for ultraportable laptops

Toshiba has launched two new 1.8in hard drives – one 80GB model, and a 160GB version – which it claims can reduce the storage footprint in ultraportables and mini laptops by as much as 40 percent compared to traditional 2.5in drives.

Toshiba said the single-platter 80GB MK8017GSG and dual-platter 160GB MK1617GSG drives will ship to mobile PC manufacturers and resellers in August. Patty Kim, product marketing manager at the Toshiba Storage Device Division declined to disclose pricing plans.

Kim said the single platter 80GB drive replaces Toshiba's two-platter 80GB MK8016GSG 1.8in drive that was unveiled in February. Toshiba upped the areal density on its single-platter 80GB drive to 246.8 gigabits per square inch, compared to the older model's 182.8 gigabits per square inch.

Further, the new 80GB device weighs 60g and has one head, as opposed to its two-head 62g predecessor, making it a better fit for mobile PCs.

Both of the new drives include a 3Gbit/sec serial ATA interface, have an average seek time of 15 milliseconds, 8MB of cache, and spin speeds of 5,400 rpm. Energy consumption is 0.0028 watts/GB for the 160GB model and 0.0056 watts/GB for the 80GB version, noted Kim.

IDC predicts advances in mobile processor and wireless connectivity technologies over the next few years will significantly boost demand for thinner and lighter mobile PCs. According to a report released last month., the research firm projects that shipments for thin-and light mobile PCs will climb to over 26 million units by 2012.

Kim said that Toshiba sees increased interest from consumers for more storage in convertible PC tablets and other small-form factor PCs including hinges with moveable screens and sleeker overall designs.
