TerraMaster touts the F4-425 as ideal for those who want a practically plug-and-play new NAS with Intel x86 architecture. It is rated to support up to 36% more storage than its immediate predecessor, and features a custom TRAID array that might deploy it up to 30% more efficiently than RAID5. The F4-425 is also rated to be fully compatible with apps such as Jellyfin, Plex and Google Drive, and to support two-way "millisecond-level" syncing with personal devices via TerraSync.
