When the time chain reaches 1TB in storage space, how easy is it to add another hard drive SSD?
Discussion
Depends what hardware you're running.
Samsung 1TB SSD hard drive. My node is Umbrel
Raspberry Pi 4GB model
IIRC Umbrel has a guide somewhere how to replace the drive with a bigger one. I would recommend against running two external drives on a RPi. If you move to 2TB, you'll be good for at least another 5, maybe 10 years.
