Samsung has been trying to squeeze as much storage as it can into its latest flash chips, and it's done a good job: these 128-gigabit chunks of silicon are, apparently, the industry's highest density memory storage available.
The new chips use super-compact three-bit multi-level-cell, 10 nanometer process technology to pack the storage in. Sounds awful, but really it just means that these chips manage to squeeze more memory into the same dimensions as usual flash storage.
The high density doesn't just make these things compact, either: they can swap data at a lightning fast 400 megabits-per-second. The new chips will feature in a range of new, high-capacity memory cards and SSDs in the coming months.
