OCZ conquers Everest, flashes 3-bit NAND at world

OCZ is showing the first mainstream computer flash drive using 3-bit NAND at CES 2012. Flash comes in single-level cell (SLC) form, the fastest, longest-lived and most expensive, and also a 2-bit multi-level cell (MLC) variant which is slower, has a shorter working life but is less expensive than SLC. TLC is an extension of this …
