320 TERABYTES in a normal case!! - The DIY 4k editing NAS

The video demonstrates the construction of a 4K video editing NAS housed in a 320‑terabyte case, capable of supporting up to 18 hard drives. The builder selects Seagate IronWolf Pro NAS drives (16 TB each) and a Strix gaming motherboard that supports Ryzen 2600, two M.2 slots, and PCIe expansion. A modular power supply with a Molex cable powers the drives, which are connected via SATA and an HBA card; cable management is handled with ties and an extra SATA cable for future expansion. The system is configured to run Proxmox, with a RAID Z3 array and hot spares, and the presenter highlights the importance of proper mounting screws and vibration isolation. The build includes a 200‑GB tempered glass side panel and monitors disk usage with NetData. An Unraid array is created with one parity disk, allowing recovery from a single drive failure; adding a second parity disk would give up 32 TB of space and allow recovery from two drives. Unraid’s cache feature is used for fast SSD writes, and the presenter plans to run VMs on a RAID‑1 SSD set in the M.2 slots. A new feature automatically pauses parity sync during formatting, and the “turbo write” (reconstruct write) is enabled. The “most free” setting directs writes to the drive with the most free space, useful for ingesting 18 separate 100‑GB video clips. The chassis fans run at 700 rpm, and the network cable is moved from the onboard gigabit port to a 10‑gigabit Quantcha card. The system pulls over 3.5 Gbps, with write speeds around 350 MB/s and drive temps staying between 39–48 °C. The build includes a six‑core CPU, 16 GB RAM, 10 Gbps networking, 20 hard drives, two M.2 SSDs, and two SATA drives. The presenter compares the cost to an off‑the‑shelf NAS, noting the system is cheaper and more flexible. The video is sponsored by FreshBooks, an accounting solution for small teams.

Viewers praise the detailed build process and the cost‑effective approach, noting the use of Seagate IronWolf Pro drives and the Strix motherboard as key strengths. Comments highlight the clarity of the cable management and the effective use of Unraid’s cache and parity features. Some viewers suggest adding a second parity disk for extra redundancy, while others appreciate the 10‑gigabit Quantcha card for faster network throughput. Overall sentiment is positive, with high engagement reflected in the 3.5 million views and multiple likes on the top comments.
