Intel has officially announced its first consumer solid-state drive (SSD) to feature 20nm NAND flash components: the 335 Series.
Based on a SandForce SF-2281 controller, the Intel 335 Series uses 20nm multi-level cell (MLC) flash components to provide a claimed 500MB/s sequential read and 450MB/s sequential write device, along with claimed 42,000 read and 52,000 write input-output operations per second (IOPS.)
Developed as part of the Intel-Micron Flash Technologies (IMFT) joint project, the device was originally announced as in development back in April but today marks its first availability at retail in the UK.
The first Intel 335 Series SSD will be a 240GB model based on 64Gb 20nm planar cell components, designed in such a way as to match the performance and endurance characteristics of 25nm parts while packing more components onto a wafer and theoretically reducing the cost correspondingly.
'The Intel SSD 335 uses high-K metal gate [HKMG] planar cell technology, which overcomes NAND process scaling constraints to deliver the smallest-area NAND cell and die in the industry,
' boasted Intel's general manager for non-volatile memory Rob Crooke at the announcement. 'By pushing technology constraints and using process innovation, Intel can continue to progress SSD technology and pass along savings to our customers.
The Intel 335 Series uses the usual 2.5" form factor, measuring 9.5mm thick and weighing 78g. A SATA-III 6Gb/s interface is included, while the first parts will boast a low pwoer draw of around 350mW active and 275mW idle.
The Intel 335 Series 240GB SSD is available from Overclockers UK
for £161.99 immediately, with other retailers expected to follow shortly with similar pricing. Thus far, Intel has not confirmed pricing or details of any other parts in the range.
