SSDs are picking up steam in the computer market (although there were some bad news), and so it comes as no surprise that today Toshiba announced the world’s first laptop featuring their self-developed 512GB SSD [JP]. The Dynabook SS RX2/WAJ went on sale in Japan today already and costs $4,000.

Spec-wise, buyers get a Core 2 Duo SU9400 CPU (1.40GHz), 3GB of RAM, a DVD super multi drive, a 12.1-inch WXGA LCD screen, Bluetooth 2.1+EDR, WiFi IEEE 802.11a/b/g/n, Gigabit Ethernet and 12 hours of battery life.

The SSD (which costs $1,500 by itself and is pictured above) features 230MB/s reading speed and 180MB/s writing speed. Toshiba says this is 2.5 to 3 times better than a comparable HDD.

The Dynabook weighs just 1095g and is sized at 283×215.8×19.5〜25.5mm. Toshiba is yet to speak about their plans to export the notebook to overseas markets.
