Intel is set to replace its Larson Creek series (311 series) just in time for the Ivy Bridge processors with the Hawley Creek series (313 Series). The 313 series will use 25 nm SLC NAND flash memory and be designed for Ivy Bridge's new 7-series chipset, while maintaining backwards compatibility with current 6-series chipsets.
In addition to moving to 25 nm NAND flash from 34 nm NAND flash, Intel will now be offering two capacities of 20 GB and 24 GB with the 313 series (only 20 GB with the 311 series). We aren't exactly sure what the extra 4 GB will give you in a cache drive outside of the extra capacity, but Intel has added it for a reason, so we'll have to play the waiting game on its benefits. As with the 311 series, the drives will still utilize a SATA 3.0 Gb/s interface and will be based on either a 2.5-inch or mSATA form factors. The 2.5-inch drives will be 7 mm tall versus the 9 mm of the 311 series. This move continues the trend by most SSD manufactures to decrease the size of SSDs to allow the drives to be utilized in Ultrabooks.
As for pricing, it looks like Intel's MSRP for the 20 GB model is around $99 dollars and the 24 GB around $119 dollars. These new drives should be available for purchase around the time-frame of the Ivy Bridge and 7-series chipsets launch.
