This is not a new update, but I only found out about it recently.
A new BIOS update called 223 and something else. It seems that the “something else” part seems to improve the eMMC storage performance, but it needs BIOS 223 to work.
This is what I saw on the Asus Live Update application.
I wanted to see if it really improved the eMMC storage performance. So I ran Crystal Disk Mark before installing the updates. These are the scores that I got.
