Both put your files on the home network. One is free with hardware you already own; the other is a small computer built only for storage. The right choice depends on three things: how much data, how many people, and how much the data matters.
The video shows the router route working beautifully for office file sharing — and for many homes it is genuinely enough. But "enough" has limits, and honest ones. This comparison skips marketing and lines up the practical differences: speed, safety of your data, features and running cost, so you can decide with open eyes.
The four rows that decide it for most homes — speed, drive failure, features, cost.
Cost: zero. You already own the router, and most homes have a spare drive in a drawer. For sharing documents, keeping a family movie folder, receiving phone photo backups and light office file exchange, it does the job today, silently, using very little electricity. There is no second box to buy, configure, or listen to humming in the corner.
A NAS has a real processor and a gigabit-or-faster connection dedicated to storage, so it sustains around 100 MB/s and serves several people at once without slowing down. The router shares one small CPU between routing, Wi-Fi and your files — one big copy can make the whole house's internet feel sluggish. Two or three light users: router is fine. A family streaming, backing up and syncing all evening: NAS territory.
A router setup stores everything on one drive. When that drive dies — and all drives eventually die — the files die with it. A real NAS typically runs two drives in RAID 1, so one can fail completely while every file survives, and it adds scheduled backups, snapshots and recycle bins. If the drive holds the only copy of family photos or business records, this row alone justifies the NAS — or at minimum, a second backup of the router drive.
NAS software includes phone auto-backup apps, folder sync between PCs, media libraries with transcoding, user quotas and proper logs. Router sharing gives you folders, basic users and DLNA — enough for simple jobs, nothing more. Ask yourself which list describes your actual routine, not your someday plans.

▶️ Watch Full VideoYes, and it is a sensible path. Your files stay in normal folders on the drive; when the NAS arrives, copy them across the network and retire the router share.
For speed and features, yes — a PC share beats a router easily. The costs are electricity, noise and maintenance. Many homes use the router for light sharing and keep the PC off.
Yes. RAID protects against one drive failing, not against deletion, ransomware, theft or fire. Important data follows the same rule everywhere: at least two copies, one somewhere else.
