HDD supply may be less than demand in 2010, ASPs could increase as a consequence

December 16, 2009

Analysis of:Supply of 3.5-inch HDDs tight until March 2010, say Taiwan PC makers | www.digitimes.com

Taiwan PC makers report that 3.5-inch drives are in short supply and may remain so until March 2010. HDD inventory for almost all products is very low coming out of 2009 supporting smaller than usual supplies in 2010. HDD companies and key component suppliers have held capital spending to a very low level in 2009, this restricts the ability to make components to meet HDD demand in 2010. Tighter supply will lead to higher ASPs leading to higher revenue and profitability in 2010

Google Jumping Gun on SSD Support

November 30, 2009

Analysis of:Google Chrome OS will not support hard-disk drives | www.computerworld.com

Google announced that the upcoming release of the Google Chrome operating system will not support products with hard disk drives. Google believes that solid state drives are the key to a seven-second boot time on a PC. Applications will be run from the web with the Chrome OS and only the OS and user data will be stored locally. Because of the growth in user data on computers, including netbooks, it is unlikely that SSD-only computers will be highly successful anytime soon.

Optical disc drives being replaced by flash memory in computers?

November 4, 2009

Analysis of:PC makeover: slimmer profile, no DVD drive | www.mercurynews.com

Many PC makers are not including optical drives, especially for laptops and netbooks. Leaving out optical drives is being done not to reduce cost but to allow slimmer laptop and netbook computers. Flash memory with built in programs and entertainment content are now on the market in USB as well as memory card formats. Downloading content and applications has become more common, replacing one of the big uses for optical drives in computers. As flash memory $/GB declines and as write speeds for flash devices improve will these devices replace current optical disk physical distribution formats?

Rare earth metals ban by China could impact hard disk drive production
