Without making much noise about it, Corsair retrofitted its Neuton GTX line of performance consumer SSDs with 19 nm Toggle-NAND flash chips made by Toshiba. The newer drives' model numbering scheme looks like "CSSD-NxxxGBGTX-BK," where "B" denotes 19 nm Toggle NAND flash, and "xxx" denotes the capacity (120/240/480 GB). The MTBF on Corsair website appears unchanged, so does the 5-year product warranty, and rated P/E cycle count of 3,000. The Corsair Neutron GTX line of performance SSDs were launched in September 2012, originally with 24 nm toggle-NAND flash.
