Frequently Asked Questions
How much storage do I need for a Plex server?
A 4K movie averages 30-60 GB, while a 1080p movie is 5-15 GB. A 4TB drive holds roughly 80-100 4K movies or 300+ 1080p movies. Start with a 2-bay NAS and two 4-8TB drives in RAID 1 (mirrored) for both capacity and data protection.
Can a NAS transcode 4K video for remote streaming?
Yes, if it has hardware transcoding support. NAS units with Intel CPUs and QuickSync can transcode one or two 4K streams simultaneously. For remote playback where clients can't direct-play, transcoding converts the video on-the-fly to match the client's bandwidth and format requirements.
Synology or QNAP NAS for Plex?
Synology is generally preferred for Plex due to its more polished software, easier setup, and better community support. QNAP offers more hardware power per dollar, which benefits heavy transcoders. Both run Plex natively. For most home users, Synology's simplicity wins.
