Plex and Media

It depends on how your files are played. Direct play, where the original file is sent without conversion, generally requires less server processing than transcoding. Use the hardware transcoding guide to understand that distinction, then compare options in the Plex NAS buying guide. If you already own a NAS, begin with the general setup guide before deciding that replacement hardware is necessary.

It depends on the number of titles, their file sizes, desired growth room and whether the NAS will store anything else. Use the media-library storage guide for planning and the NAS Sizing Wizard for a starting estimate. Drive choices are covered separately in the Plex NAS hard-drive guide.

Both can organise and serve a self-hosted media library, but the better fit depends on the experience, device support and level of control you want. See the dedicated Plex versus Jellyfin comparison.

Buffering can come from the network, the playback device, the media file, server load or unexpected transcoding. Work through the checks in the Plex buffering troubleshooting guide before assuming the NAS is too slow.

Potentially, if the television offers a suitable Plex client and can play your media reliably. When the television lacks the required app or struggles with your files, compare client options in the streaming-device comparison or the Fire TV guide.
