WPCE - Toshiba debuts Bluetooth hard drive for PDAs

Toshiba has married its card-size hard disk drive with Bluetooth wireless technology to come up with a portable storage device aimed at PDA (personal digital assistant) users who need large-capacity storage. The Hopbit will be publicly unveiled at the World PC Expo show that runs in Tokyo from next Wednesday, Toshiba said.

The device contains a 5G-byte version of one of Toshiba's 1.8-inch hard disk drives and offers about 80 times the memory storage space offered by Toshiba:s Genio 550 PDA and 10 times the capacity of the largest memory card on the market. It will hold around 1,000 average-length MP3 audio tracks, 3,000 digital images from a 3-megapixel camera or 37 hours of MPEG4 video encoded at 320 by 240 pixels and 15 frames per second, said Toshiba.

A Bluetooth transceiver embedded in the Hopbit means it can be accessed from the PDA and also from other devices equipped with Bluetooth, such as desktop PCs. Bluetooth's device-linking function and proprietary software should ensure that data remains accessible only by approved users, said Toshiba.

The Hopbit B105H will go on sale in Japan from Nov. 1 and will cost ¥50,000 (US$410) making it an attractive option for PDA or mobile PC users that want extra storage space at a low cost. A similar investment in SD (Secure Digital) memory cards would buy around 768k bytes of storage, or around one-seventh the space offered by the Hopbit.

The device measures 110 millimeters by 70 millimeters by 22 millimeters and weighs 180 grams. A rechargeable Lithium-Ion battery should allow the Hopbit to run in standby for around 200 hours or in operation for six hours off a single charge.

Toshiba has no plans at present to put the Hopbit on sale overseas although the company will consider such sales should it be a success in the Japan market, said Midori Suzuki, a Toshiba spokeswoman.

World PC Expo, Japan's largest PC exhibition, runs from Oct. 16 to 19 at Tokyo Big Sight. More information can be found online at http://arena.nikkeibp.co.jp/expo/ .

Ultimately this laptop has achieved everything I would hope for in a laptop for work, while fitting that into a form factor and weight that is remarkable.

It really doesn’t get more “gaming laptop” than this.

Jack Jeffries

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
