At the ongoing CeBIT show in Germany, Taiwan's A-Data showed off a 2.5-inch, 512GB solid state drive (SSD), the XPG. A-Data says the 512GB XPG is capable of reading data at 230MBps while write speeds are as high as 160MBps, though these have to be verified in real-world testing. The drive features a standard SATA II interface.
