Ask HN: How do those eMMC Windows laptops work?
2 by brundolf | 0 comments on Hacker News.
I was just shopping around for a low-end Windows laptop and discovered a new trend: machines that have 64gb or 128gb internal storage on "eMMC", which research suggests is similar to what's used in phones, and then they have a micro SD card slot for expansion (also like phones). I take it the OS lives on the eMMC and not something even weirder like a ROM chip? Do user programs and files go there too or can they only go on the SD? How does it all affect things like partitioning? Presumably this is a response to the Chromebook-pocalypse but it still feels very strange and mysterious to me for now
