According to In-Stat, SSD prices have been dropping 60% year over year. Currently, the price of consumer-grade SSD costs from $2 to $3.45 per gigabyte, with hard drives going for about 38 cents per gigabyte, according to Gartner Inc. and iSuppli Corp.
"Two years ago, SSDs cost $17.50 per gigabyte, so it's obvious that consumer NAND flash memory will soon be a true contender to hard disk drives -- it's just not there yet," Gartner analyst Joseph Unsworth said. "I think you need to get to 128GB for around $200, and that's going to happen around 2010. Also, the industry needs to effectively communicate why consumers or enterprise users should pay more for less storage."
