Toshiba Envisions 512GB SSD Drives by 2009

Toshiba is planning to ship 512GB solid state drives by 2009 when it expects these storage devices to claim one-fourth of the market, according to Japan-based reports.

The market for SSDs used in notebook PCs will surge on average 313 percent per year through 2011, according to a report from Nikkei Business Publications. The report referred to a speech given by Toshiba Semiconductor Company’s President Shozo Saito at an International Disk Drive Equipment and Materials Association (IDEMA) function in Japan on the 18th.

By 2010, SSD-based notebooks will be about 10 percent of the market, then jumping to 25 percent in 2011, Saito said.

The increase in capacity will be accompanied by sharp reductions in cost per bit, the biggest barrier to SSD adoption this year. An oft-cited example is the Apple MacBook Air. The Air model with a 64GB SSD is about $1,200 more than the model with a larger capacity 80GB hard disk drive. The price difference is largely attributed to the premium a buyer must pay for an SSD.

If the price for NAND flash memory is reduced by 50 percent per year, the price gap will shrink (by 2011) to 1.4 and 3.2 times the price of 1.8- and 2.5-inch hard disk drives, respectively, Saito said.
