First-Time NAS Setup: A Beginner Walkthrough

The box that showed up on my porch was smaller and heavier than I expected. A bare two-bay Synology DS224+ weighs about 1.3 kg empty, and the moment you slide two 3.5-inch drives in, it suddenly feels like a real machine that could eat your photo library if you get the next hour wrong.

That fear is normal, and it is also mostly unfounded.

A first-time NAS setup is really just five ordered decisions, and if you make them in the right sequence you almost never have to undo anything. Below is the exact path I walk every nervous friend through, in the order the hardware and software actually want you to do it.

What you need on the table before you touch anything

Do a quick inventory first. Rushing to power-on before you have all the parts is how people end up with a half-built pool and a drive sitting in a static bag for three days.

Here is the short list I lay out every single time.

• The NAS unit itself and its power brick (check the wattage label, most 2-bay units ship a 60W or 90W adapter)
• Two matching drives, ideally NAS-rated models like a WD Red Plus 4TB or Seagate IronWolf 4TB
• The little bag of drive screws (3.5-inch drives usually do not need them on tool-less trays, 2.5-inch ones do)
• An Ethernet cable, plugged into your router, not a random switch you are unsure about
• A laptop or phone on the same network

Step 1: Install the drives

Power the unit off and unplugged while you do this. Slide out each tray, seat the drive so its connector points toward the back of the bay, and either clip the tool-less rails on or drive in four screws.

Push the tray back until it clicks. It should sit flush.

The first time I did this I did not push the second tray fully home, and the NAS reported only one drive. Ten seconds of re-seating fixed a problem I had blamed on a dead disk for twenty minutes.

Handle the drives by their edges and set them on the box, not the bare tabletop. A hard drive is a precision instrument, and a knock while it is out of its anti-static bag is exactly the kind of small mistake that shortens its life.

A quick note on drive counts

Two drives is the sweet spot for beginners. It lets you run a mirror, so one drive can die and your data survives, and it keeps the math simple.

Four-bay units exist and are tempting, but they roughly double the cost and add layout decisions you do not need yet. Start with two, learn how the system behaves, and expand later once nothing about the process scares you.

Step 2: Power on and find the box on your network

Plug in Ethernet, then power. Give it two to three minutes. The status light will blink amber while it thinks and settle to a steady green or blue when it is ready.

On Synology, open a browser and go to the official device finder, which locates any Synology on your local network. QNAP users can use Qfinder, and TrueNAS users read the IP straight off an attached monitor.

If nothing shows up, the cause is almost always the cable or the port. Swap the Ethernet cable and try a different router port before you assume the hardware is faulty.

Step 3: Install the operating system and create your account

The web wizard walks you through installing the system software, called DSM on Synology or QTS on QNAP. This takes about ten minutes and the unit reboots once in the middle. Do not unplug it during this part.

Then you create the administrator account.

Pick a real username, not admin, and a password you store in a password manager. A mistake I see constantly is people using a throwaway password on a device that will eventually hold every family photo they own. Treat this login like it guards a safe, because it does.

The wizard usually offers to disable the default admin account and enable automatic security updates. Say yes to both. That single toggle blocks the most common automated attacks that target NAS boxes exposed by accident, and it costs you nothing.

If you are asked whether you want to create an online account, that is optional. You can run the whole NAS on your local network without ever signing up for a cloud service, and for a first setup I suggest keeping it local until you are comfortable.

Step 4: Choose a storage layout and build the pool

This is the one decision that is genuinely hard to change later, so it deserves a minute of thought. With two drives you are really choosing between two options.

Pick the mirror. Yes, you give up half your raw capacity, but the whole point of a NAS is that a single failed drive is a shrug and a replacement, not a disaster. Synology calls its beginner-friendly flexible option SHR, and it behaves like a mirror on two disks.

The system then builds the storage pool and a volume on top of it. On 4TB drives this parity build runs in the background for several hours, sometimes overnight. You can keep working while it churns, so do not wait on it.

Step 5: Create users and shared folders

Now the fun part, because this is where the NAS starts acting like the file server you actually wanted.

Create a shared folder first. Give it a plain name like Photos or Documents, and if the option appears, leave encryption off for your first one so you do not lock yourself out.

Then create a user account for each person in the house, and assign permissions per folder.

The pattern I recommend for a family: give each person read-write on their own folder, read-only on shared archives, and no access at all to anyone else's private space. It takes five minutes and it saves the awkward conversation where someone deletes a folder they did not know was important.

Connecting from your computer

On Windows, open File Explorer and type the NAS address like 192.168.1.50 into the bar, then log in with the user you made. On a Mac, use Finder, choose Go then Connect to Server, and enter smb://192.168.1.50 instead.

Map it as a network drive so it reappears every time you boot, and you are done.

Where this leaves you

An hour of careful clicking gets you a mirrored, always-on file store with real user accounts, and the only genuinely irreversible choice you made was the mirror layout, which is the safe one anyway.

Spend your next session setting up an actual backup and a photo-sync app, because those are what turn a box of spinning drives into something your whole household quietly relies on. The setup you just finished is the foundation everything else sits on, and you built it in the right order.
