Dash for Flash: Seagate in NAND cash splash

You can't even afford to blink in the flash storage business without something big happening. Now Seagate's gone and invested in DensBits, the start-up that aims to make cheap slow NAND perform as well as fast flash. There are three kinds of flash: single-level cell or SLC, with 1 bit per cell, which is fast and long-lived; 2- …
