Hi,
I just found an old RPI 3 b+ and wanted to make a little media center to watch some movies and tv shows on it.
I connected a SSD with an usb to sata adapter, but when I try to play a video it just doesnt work, its hardcore lagging and not buffering at all.
I used LibreElec for this, and the files are mostly 1080p.
Im a total noob at this RPI stuff and have no idea how to fix this.
