SECTOR SIZE is not optimal
Created by: fneddy
the SECTOR_SIZE ist currently set to 512 Bytes
pub const SECTOR_SIZE: usize = 512;
Current flash storage systems (SSDs/SD) use internally a minimal structure of 4k to 4mb.
Increasing the SECTOR_SIZE would probably enhance the speed. Through it might not be practical due to memory waste.
Perhaps there are other solutions for this problem. (additional translation/buffer level, or variable sector size).
