The problem is that while flash memory is faster than a spinning platter, it is also much more expensive per gigabyte. Over the weekend details leaked about Intel's SSD roadmap, and what's most interesting about it is that the capacities of Intel's SSDs are going to increase in a big way. First off is a refresh to the high performance X25-M range of SSDs. Currently available in 80GB and 160GB models, these will be replaced by a new design, codenamed Postville, which will come in 160GB, 300GB and 600GB variants."
