Buffalo has added a new 512GB SATA III solid state drive to their range this week with the immanent launch of their new SSD-N512S/MC400 on to the Japanese market. The new SSD-N512S/MC400 is capable of a 405MB/s of data transfer rate (reading speed).
The new Buffalo SSD-N256S/MC400 256GB SSD was released last week in Japan for 72,200 Yen or around $883.
However no information on pricing or worldwide availability has been released as yet, but as soon as it becomes available we will let you know. But I would expect the new double capacity drive would be in the region of 140,00 Yen $1,600.
