TechPowerUp reports Corsair has updated its Neutron GTX solid state disk lineup with 19nm Toggle-NAND flash memory chips made by Toshiba. The new disks have a numbering scheme like "CSSD-NxxxGBGTXB-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, but we're not sure if the same can be said about the drive's maximum programmed-erase cycle count (P/E cycles). When an SSD meets its P/E cycle limit, it typically switches to a read-only device. While you won't lose any data, you'd need to back-up and RMA the drive.
