We heard way back in January that ASUS' S121 would be the world's first laptop with a 512GB SSD, and now we've reason to believe that very drive could be coming from the labs at A-DATA. Here at CeBIT, the company has launched what it's claiming is the industry's highest capacity SSD (in the 2.5-inch form factor) with its 512GB XPG SSD. The drive promises to provide 230MB/s read and 160MB/s write rates while shuffling data around on the SATA II interface. As expected, it comes housed in a durable aluminum casing to shake off those occasional bumps and bruises, but there's sadly no word on price or availability. Next stop: 1TB. (Hopefully, anyway.)
