I have a very slow reboot of raspberry pi 4 (8gb ram). It wasnt always like this, but the last days i realized it's extremely slow. I use it for Home assistant (with Docker), pihole and plex, and i have a usb mounted for extra space. Is the SD card getting old and i should go for an SSD? Here are my results:
