Disk is dead, screeches Violin – and here's how it might happen

Analysis And in a flash, disk is dead. Well, actually, not that fast. But flash array flogger Violin Memory is convinced disk is dying in the data centre, killed by a series of NAND acronyms: 2D MLC, 3D TLC and, the final blow, 3D QLC. Is this view realistic? Even remotely realistic? It starts from a pair of observations by Violin …
