Solid-state drives are extremely fast and efficient, yet users generally complain about their minimal storage capacities that barely reach 64 GB in mainstream notebooks. Laptop PC vendors are usually reluctant when it comes to packing large capacity offerings because they have to increase the selling price for the device, which makes it less appealing to the customers.

However, Toshiba decided that it's time to bring in the big guns and released a capacity update to its 12.1-inch Dynabook SS RX1, that will hit the Japanese market in 128 GB SSD versions. The RX1/TAE model boosts the notebook's previous performance with 128GB of solid state disk and an internal, KDDI EV-DO data module.

The impressive SS RX1 was introduced back in June last year, and the rest of its features remain unchanged. Under the notebook's sleek hood, the user will find an Intel Core 2 Duo U7600 processor running at 1.2 GHz, 2GB of memory, Intel 945GMS Express graphics, a LCD display running at a maximum resolution of 1,280 x 800, powered by a 6.2 hour or 12.5 hour battery pack.

However, even though the update aims at introducing both the 128 GB solid-state drive option and the WIN 1x CDMA module from KDDI, users won't be able to get both of the SSD and the CDMA card on the same laptop PC. The CDMA-enabled version comes with a standard 80 GB of conventional hard-disk drive, but promises to unleash wireless wide-area networking (WAN Wireless) capabilities.

The Dynabook SS RX1/TAE models will be available for sale on the Japanese market only starting next month, and come with an impressive price tag of ¥400,000 or more than $4,000 for the basic options only. The full-options version will punch a hole of $6066 in your budget, which makes the update useless, given the fact that users would pay the same for purchasing a stand-alone 128 GB SSD and swap it in their own garage workshop.
