Im using a nano every and nrf radio to monitor my garage. Because of loud sirens that could be set off upon break ins, I want to monitor it for a few weeks first and log what it’s doing before connecting the sirens. It will just be a few strings of text on certain events. Not much. Can I do that within the nano or do I need to buy an SD card adapter or something else with more memory?
Nano Every (Arduino Nano Every — Arduino Online Shop) only has 256 bytes of EEPROM... if you are only expecting a small amount of data you could use that.
If not, then SD card.

The Sparkfun OpenLog works very well and is a real bargain!
I've collected arbitrary amounts of serial data for months at a time.

I am a fan of FRAM, 8Kx8 for under $5.00 US. They can be gotten in SPI or I2C and they are nonvolatile and will read and write as fast as the interface will allow, no delays and trillions of r/w cycles. They work fine with Nano and all of the others.
Agree here, like that it`s so easy to use.
