25 January 2011, Neuss – Toshiba Europe Storage Device Division, the world leader in high performance, small form factor hard disk drive (HDD) technology, today announced its largest capacity 1.8-inch (4.6cm) form factor HDD in a 5mm height to date. At 220 GB[1][1] the MK2239GSL single platter SATA HDD offers the highest capacity per space available in a 1.8-inch (4.6cm) form factor HDD. Its super slim frame of just 5mm makes the MK2239GSL ideal for use in compact mobile devices. These include digital video recorders (DVC), personal media players and compact external HDDs as well as media tablets, notebook PCs, mini-notebooks, thin-and-light, and ruggedised laptop PCs where high storage capacity coupled with sleek, slim line design is essential.
Toshiba is the market leader in the 1.8-inch (4.6cm) form factor HDDs and has shipped over 80 million 1.8-inch (4.6cm) HDDs to date. A recent report from IDC shows that in Q3 2010, Toshiba shipped over 92 per cent of the 1.8-inch (4.6cm) HDDs worldwide, retaining its number one market share position since entering the market in 2000. As the market leader in 1.8-inch (4.6cm) form factor HDDs, Toshiba is at the forefront of small form factor technology innovation.
The MK2239GSL is part of a new line of 1.8-inch (4.6cm) HDDs, which are the first to be developed with LIF SATA connector, enabling Toshiba to produce a drive up to 10 per cent smaller foot print than those with micro SATA connector. The MKxx39GSL HDD series has also been developed using long sector formatting, an advanced format technology that Toshiba has used since 2007 due to its ability to increase storage capabilities. This combination of both LIF SATA and long sector formatting enables Toshiba to produce HDDs that provide both a high quality performance and large capacity, yet are still portable and compact.
The MKxx39GSL line of HDDs includes the following products: the MK1639GSL, the MK2039GSL and the MK2239GSL, all with capacities of 160GB, 200GB and 220GB respectively. However, these large capacities do not mean a compromise on energy efficiency. With an energy consumption efficiency[2][2] of 0.0016W/GB, the MK2239GSL uses 30 per cent less power than previous models such as the MK1634GSL. It not only surpasses its 1.8-inch (4.6cm) predecessor in energy efficiency, but also in 2.5-inch (6.4cm) form factor as well. The lower power consumption of the MK2239GSL will increase battery life, essential for mobile multimedia devices such as notebook PCs or tablets, which are often used to view video and TV content and play music, requiring longer battery durability.
The MKxx39GSL line has been designed with portability in mind. Weighing just 48 grams, it can withstand up to 1,500 Gs of non-operational shock and 600Gs operational shock, a vibration robustness that surpasses even 2.5-inch (6.4cm) form factor durability. This means it can withstand tougher mobile conditions, for example when being transported from place to place, or if the device were to be dropped. Each HDD also has a high buffer memory of 16MB and interface transfer rate of 1.5 Gb/sec. This enables the fast transfer of media data, ideal in mobile consumer devices where quick access to high resolution images and AV is essential.
“In this digital age, access to media data on the go is increasingly important. The popularity of portable PCs and mobile devices has led to the development of increasingly compact devices,” said Martin Larsson, Vice President, Toshiba Europe, Storage Device Division. “The 1.8-inch form factor is ideally placed to meet the storage needs of this new generation of consumer electronics, delivering a high capacity in a slimline frame. As market leader in 1.8-inch HDDs, Toshiba is dedicated to the innovation of this form factor, the MKxx39GSL HDDs have been developed with leading-edge technologies, to provide OEMs with compact, high capacity storage solutions that won’t compromise on battery life.”
The environmental impact of the MKxx39GSL HDD line has been reduced by the elimination of halogen and antimony in its manufacture and all are RoHS compliant.
The MKxx39GSL will be readily available from February 2011.

Note: Toshiba defines a megabyte (MB) as 1,000,000 bytes and a gigabyte (GB) as 1,000,000,000 bytes. |

[1][1] [1][1] One Gigabyte (1GB) means 109 = 1,000,000,000 bytes and One Terabyte (1TB) means 1012 = 1,000,000,000,000 bytes using powers of 10. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB= 230 = 1,073,741,824 bytes and 1TB = 240 = 1,099,511,627,776 bytes, and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system and other factors.
[2][2] Energy consumption efficiency is calculated in accordance with the Law Concerning the Rational Use of Energy in Japan, which was enacted in 1979 to promote energy conservation and reduce energy consumption. The Law Concerning the Rational Use of Energy was most recently revised in 2009 with specific measurement criteria reflected in the specification indicated. Calculation of Energy consumption is dividing consumed energy by the capacity. The consumed energy and capacity shall be measured and specified by the Law Concerning the Rational Use of Energy.
