Video Description

I built a custom 4-bay NAS using a Raspberry Pi 5, full-size 3.5" drives, and a fully 3D-printed enclosure. It features swappable drive trays, RAID 5 with OMV, and surprisingly fast performance, especially with a 2.5G Ethernet adapter. Everything from design to testing is covered!
