Toshiba Corp. has unveiled the world’s highest-density hard drive for mobile and small form-factor computers that can store up to 1TB of data. The novelty also uses the world’s highest-density platters, which allow the product to provide whopping capacity with three platters, thus, slightly increasing the height of the hard disk drive (HDD). The firm also launched dual-platter 750GB drive with standard dimensions.

MK7559GSXP and MK1059GSM hard drives use Toshiba’s own technology to improve the perpendicular magnetic recording technology head and disk and realize the industry's highest areal density of 839.1Mb/mm² (541.4Gb/in² or 67.6GB/in²) and capacities of 750GB or 1000GB, the industry's largest for double platter and triple platter 2.5” hard disk drives.

With the exception of the capacities, number of platters and heads as well as height (9.5mm vs. 12.5mm), the  MK7559GSXP and MK1059GSM have similar specifications: 5400rpm spindle speed, 8MB of cache, Serial ATA-300 interface, 12ms average seek time, etc. The 1TB model with higher amount of platters naturally consumes slightly more energy 2.2W in seek mode and 1.7W in read/write mode compared to 1.85W and 1.5W for 750GB model, respectively.

The new products offerings expand Toshiba's mobile HDD product line into the highest-capacity segment of the 2.5” HDD market and represent the company's first mobile HDD platforms developed with the combined engineering resources from the integration of Fujitsu's HDD business, which Toshiba acquired last fall.

Sample shipments will start from April, 2010.

Toshiba Unleashes World’s First Mobile 750GB, 1TB Hard Drive.


Somehow are we not missing a bit of research here? Just to set the record straight, there have been 640GB, 750GB, and also 1TB drives on the market now for a while already from Western Digital. So then, how isToshiba the world's, uh, 'First'? Give credit where credit is due. Granted the WD 1TB drives are 12.5mm versus 9.5mm, but nonetheless they are still 2.5" notebook drives. Besides, they are easily accommodated in the Unibody Macbook Pros without any hassle.

Well, I'm a reseller myself and I haven't seen ANY SAMSUNG or WD mobile drives larger than 500GB in my supplier's catalog. So ... these 12,5mm drives from WD are very scarce...
