Storage.read vs Flash.read ? bangle Storage based the extranal flash

So, I confused about require("Storage").read RAM less or RAM more

It's as the docs say - it doesn't use RAM, it just returns a memory-mapped String pointing to flash.

I believe that comment was about Tensorflow. Tensorflow is unable to work directly from the flash memory so in Tensorflow's case you have to load from Flash into RAM.

returned data between require("Storage").read with A string of data and require("Flash").read with A Uint8Array of data

require("Flash").read actually loads straight into RAM, but require("Storage").read doesn't.

Realistically there's not really much of a case where you should be using require("Flash") now, unless you're doing something very low level
