Samsung has launched a raft of products that lend weight to the notion Apple may reveal a Flash memory-based subnotebook Mac next week at Macworld Expo in San Francisco.

The announcements include the world's first 128GB Flash memory card to be made available for mass-market implementations. These drives will be launched later in the year in 1.8-inch and 2.5-inch versions.

It is worth noting that the hard drive-based iPod classic hosts a 1.8-inch drive, so this news sparks possibility of an all Flash memory iPod range in the not-too-distant future.

Samsung's 128GB SSD will be demonstrated in a notebook PC at CES 2008 in its Semiconductor Product Showcase, Room N236, at the Las Vegas Convention Center. It offers a write speed of 70MB/s and a read speed of 100MB/s. It also offers a 3.0 gigabit-per-second SATA II interface and low power consumption (c.0.5-Watts in active mode).

Web-Feet Research predicts the market for solid state drives will reach $570m in 2007, climbing to a value of $6.6bn by 2010.

With a view to mobility, Samsung also confirmed that it is now shipping Compact Flash card-sized hard disk drives (HDD) for use in mobile devices, initially in 30GB and 40GB models. These are called Spinpoint A1 hard disks and boast significantly higher storage capacity than conventional memory cards, the company claims.

"Samsung is leading the blockbuster demand for portable consumer devices that offer greater capacities for storing information, music, videos and games," said Andy Higginbotham, director of hard drive sales and marketing, Samsung Semiconductor. "This new drive will fit within the dimensions of the already widely adopted Compact Flash type II card form factor."

The company also unveiled a 31-inch OLED screen, and recently confirmed a 500GB hard drive for laptops. The latter consists of three 166GB platters in a 2.5-inch hard disk drive frame measuring just 9.5mm in height.
