Intel will be transitioning its SSD lineup to the 25nm manufacturing process by Q4 2010 according to a leaked Intel SSD roadmap slide.

A joint venture between Intel and Micron earlier this year has resulted in Intel-Micron Flash Technologies (IMFT) 25 nm MLC NAND flash memory  that will be used in the “G3″ version of Intel branded SSDs.  It is expected there will be three X25-M drives, listed as 600GB, 300GB and 160GB models, along with an X25-V 80GB all available by the end of 2010.

The lineup is still a part of the “Postville” series, however, along with the chip shrink, the SSDs will bring a new controller,  data encryption, S.M.A.R.T support and of course enhanced performance.

Intel also looks to expand its X25-E extreme lineup with new a Lyndonville series, boasting the same features as its other models, but with better write performance. Release is expected at the start of 2011 with 400GB, 200GB and 100GB models.

The one glaring omission on these highly anticipated drives, no SATA III 6Gbps support
