VR-Zone (who seem to have got their hands on an Intel roadmap!) have announced the availability of a new range of high-end Intel SSDs. The replacements for the current X25-M Postville (the 320 series) are still slated for March and will use 25nm flash memory. The 320 series drives will be available in models from 40 to 600 GB.
In terms of the Intel range overall, the new series (510) falls between the forthcoming 320 series range and the current X25-Es (based on SLC memory), still using 34nm MLC NAND (like the current Postvilles). It will have a Serial ATA 6 Gb/s interface and an extensively modified memory controller, with read speeds announced at 470 MB/s and writes at 315 MB/s. VR-Zone is announcing launch of these products for March 1st. The 120 and 250 GB models will cost 280 and 580 dollars respectively.
