So the sample that has arrived in our secret test facility is the 240GB version of the drive. The 335 series will come with MLC NAND, flash memory from the 20nm node. Intel has not yet released a spec sheet on the memory though Intel's proprietary NAND flash used is labeled: 29F16b0bccmF2.
Now if you where hoping for a propyitary Intel controller, we'll have to dissapoint you. The SSD makes use of the LSI SandForce SF-2281 controller and SATA 6 Gb/s interface to deliver read speeds up to 550 MB/s and writes up to 450 MB/s depending on volume size of the SSD.

Initial tests straight away show us that the product is fast alright but enthusiast class performance, this product stays in vicinity of the latest Marvell, Indilinx and sure, Intel's previous latest and greatest as well.
The NAND merged with the LSI controller this has 20nm architecture and was produced with IM Flash Technologies (IMFT). Good to know is that Intel applies a customized firmware to the controller which, as far as we know, is as bug free.
There's nothing more trivial as pricing, Intel has set an MSRP (Manufacturer suggested retail price) of $184 for the 240 GB drive. This is what i was talking about on the previous page, the 20nm node allows for cheaper production NAND flash and thus pricing.
Intel 335 SSD review We review the Intel series 335 SSD with test and benchmarks. Intel has developed this product under codename Jaycrest and is the first SSD series that moves into 20nm Nand Flash memory production. We have lots to talk about alright.
