Behind the scenes, Intel's 40GB X25-V is known as the Glen Brook drive. In order to meet its $120 price-point, the drive will use MLC NAND flash memory. It's currently shipping to system makers in sample volumes and should be widely available in January.
Meanwhile, Intel's less cost-prohibited enterprise SSD series will use SLC NAND flash chips, and should bring a 40% price cut (or about $6.50 per gigabyte), over the X25-E series. For instance, the upcoming 50GB enterprise drive is planned to have an MSRP of $350. Samples of the new lineup should ship in April and are expected to be available in July, 2010.
