ESP32 and external memory for FS

Hello,
I'm working on a project where I'm using ESP32S3 to retrieve data and store it on an SD card in a sqlite3 database. Everything works as it should, but I would like it if the data was stored in memory that can't be easily removed. So some sort of soldered chip. A memory size of maybe 512M/1G/2G would be enough for me. The question is what type would you recommend to make it work similar to an SD card and not cost too much.
Thank you for your help.

Easiest would probably to go with eMMC. You control those chips in more-or-less the same way as an SD card, so your current code will probably work un-changed.

And one more question. Is esp32s3 compatible with eMMC 5.1? I would like to use: eMMC04G-M657-K03U

I don't know exactly, but I'm pretty sure eMMC is backwards compatible, so it should work.
