Dutch tech site Tweakers writes OCZ is working on two new solid state disks for the consumer market; the Vertex 3.20 for the mainstream market and the higher-end Vertex 450.
Both disks will use 20nm NAND flash memory rather than the 25nm one used by OCZ's previous generations. The Vertex 3.20 will have a SandForce controller and will ship in capacities of 120GB, 240GB and 480GB.
The Vertex 450 was already announced a couple of weeks ago but is now nearing retail phase. This model features a custom Indilinx Barefoot 3 controller, which is based on the M10 controller from OCZ's Vector, with support for 256-bit encryption and enhanced energy management. This model promises read speeds of up to 540MB/s, write speeds of up to 530MB/s and 90,000 IOPS.
Other than that, OCZ also showed a new Vector PCI Express SSD that uses two Barefoot 3 controllers. To be available in 240GB, 480GB and 960GB editions, this disk promises over 1000MB/s transfer speeds.
