Micron announced volume shipments of its 256GB SSD are delayed from Q4 2008 to March 2009:
This follows Samsung's announcement last week that it had begun mass-producing 256GB solid-state drives.
The Micron RealSSD C200 will read data at 250MBps (megabytes per second) and write at 100MBps. It is sampling to customers now. Samsung, by comparison, is claiming sequential read rates of 220MBps, with sequential write rates of 200MBps.
The Micron representative said that the company is slightly behind schedule in delivering the 256GB product, as it was originally targeted for the fourth quarter of this year.
