I have been convinced that NAND chips have been price-fixed for years now, similar to how the exact same companies (Samsung a big one) involved in their production price-fixed RAM chips and then LCD panels. A few years ago, there was an investigation launched into exactly this. South Korea, however, closed that investigation. Has anyone heard whether that investigation was closed as one of the 'political favors' the bribes facilitated? Given the production processes involved, the materials involved, and the sheer titanic scale of the number of products which include NAND chips, it is absurd that we do not yet have SSDs which are significantly larger, and significantly cheaper, than any mechanical hard drives.
