Raspberry Pi 4 with a usb3 ssd attached. The new Pi 5s have better support for NVME drives, so you don’t need the external drive anymore. I haven’t felt the need to update the hardware though - the 4 is powerful enough for personal use (I wouldn’t try running a public electrum server on it, but for private use it works fine)
How many gb ram and ssd disk?
8G ram and 480G SSD. I use a second 3T spinning drive to store the blocks since they don’t need to be on a fast drive - only the indexes and chainstate. The blocks folder is a symlink to the slower (and larger) drive.
This works because core doesn’t do random I/O on the blocks - they are written and read sequentially, so a regular hard drive works fine.
