Cloud storage is expensive and slow when your internet drops. Here's how to build a reliable local NAS setup for engineers — covering enclosure selection, RAID configuration, drive choice, and network setup.

Standard FTC-compliant wording: "As an Amazon Associate, we earn from qualifying purchases made through links on this page, at no extra cost to you." -->The "put everything in the cloud" approach made sense for a while. It felt simple, scalable, and low-maintenance. But for engineers and developers working with large Docker containers, virtual machine images, and continuous system backups, the cracks in that approach show up quickly.
Pull a 50GB database backup over a standard home internet connection and you're watching a progress bar instead of writing code. Your internet goes down during a deployment and your entire local workflow stalls. Cloud storage bills scale with your data, month after month, with no physical asset to show for it.
This is why a growing number of engineering workspaces are adding a local Network Attached Storage (NAS) layer — not to replace the cloud entirely, but to keep frequently accessed data local, fast, and under your direct control. When your NAS is on the same local network as your workstation, data transfers happen at gigabit speeds with no external dependency.
This guide walks through the four decisions that determine whether a local NAS setup actually performs well: enclosure selection, drive layout, storage media, and network connection.
Quick Answer: The 3-Part NAS Setup
- Enclosure: Synology DS723+ — dedicated processor, runs its own OS, handles containers and backups
- Drives: Western Digital 6TB WD Red Plus — CMR technology, built for 24/7 NAS workloads
- Network: NETGEAR GS105 5-Port Gigabit Switch — hardwired local connection, eliminates Wi-Fi latency
Why a Dedicated NAS Enclosure, Not Just an External Drive
A spare external drive plugged into your computer is not a NAS. It goes to sleep when your computer sleeps, it's accessible to one machine at a time, and it can't run background tasks like automated backups or container registries independently.
A proper NAS enclosure is a small, always-on computing unit with its own processor, memory, and operating system. It sits on your local network, accessible to every machine in your workspace simultaneously, and keeps running whether your workstation is on or off.
For engineering environments specifically, the processor inside the enclosure matters — you need it to handle background encryption, network file synchronization, and container deployments without slowing down your actual work.
1. Synology 2-Bay DiskStation DS723+ — The Enclosure
Amazon rating: 4.7/5 stars from 4,769 reviews
The DS723+ is the enclosure most consistently recommended in home lab and professional NAS discussions, and the review base backs that up — nearly 5,000 ratings at 4.7 stars is a well-validated signal across a wide range of real setups.
It ships diskless, meaning you supply your own drives and install them yourself. That's actually the right approach for a technical workspace — you choose the drives that match your specific capacity and redundancy requirements rather than getting locked into whatever the manufacturer bundled.
The DS723+ runs Synology's DiskStation Manager (DSM) operating system, which handles everything from RAID configuration and automated backups to private Docker container registries and snapshot management through a browser-based interface. For engineers already comfortable with containers and scripting, DSM is genuinely capable — you can set up automated snapshot schedules, host a local package mirror, or run a private Git server on the same device.
The enclosure supports standard 3.5-inch drives, connects via Gigabit Ethernet (with optional 10GbE expansion), and has a USB 3.2 port for external drive connections and one-touch copy operations.

Understanding RAID: How to Arrange Your Drives
Once you have an enclosure, the way you configure your two drives determines how protected your data is from a physical hardware failure. This decision matters more than most people realise before their first drive failure.
A two-bay setup gives you three main options:
JBOD — Just a Bunch of Disks
Two 6TB drives become one 12TB pool. Simple, maximum capacity.
The problem: there is zero redundancy. One drive fails and the entire volume is gone — all your code, backups, and container images with it. This configuration is not appropriate for any workspace where the data has real value.
RAID 0 — Striping
Data is split across both drives simultaneously, which improves read and write speeds. Same capacity as JBOD (12TB from two 6TB drives), same fatal flaw — one drive failure loses everything.
The speed improvement from RAID 0 is rarely meaningful for the workloads a two-bay NAS handles. The risk is not worth it.
RAID 1 — Mirroring
Every byte written to Drive 1 is simultaneously written to Drive 2. Your usable capacity drops to 6TB (from two 6TB drives), but if either drive fails mechanically, the other keeps running without interruption. You pull the dead drive, slide in a replacement, and the system rebuilds itself in the background while you keep working.
For an engineering workspace, RAID 1 is the correct default. The capacity trade-off is the cost of not losing a week of work to a mechanical failure at the worst possible moment.
2. Western Digital 6TB WD Red Plus — The Drives
Recommended: new unit, not Amazon Renewed
Not all hard drives are built for NAS use. Standard desktop drives are designed to spin up when you need them and sleep in between — fine for occasional use, wrong for a device that runs 24/7 and handles constant background read/write requests from automated backup utilities.
Running a desktop drive in a NAS leads to connection drops, premature failure, and in a RAID 1 setup, a degraded array that defeats the entire point of the redundancy.
The WD Red Plus is specifically built for always-on NAS environments. The key spec to look for is CMR (Conventional Magnetic Recording) technology, which the Red Plus uses. CMR handles random, continuous write operations reliably — the kind a NAS sees constantly from backup utilities, container registries, and snapshot tasks.
The alternative, SMR (Shingled Magnetic Recording), is cheaper but writes data in overlapping layers that cause performance drops and connection instability under the continuous workload pattern a NAS creates. Always confirm CMR before buying any NAS drive.
A note on the Amazon Renewed listing: the refurbished variant of this drive shows on Amazon at a lower price. For a primary NAS in an engineering workspace, a refurbished drive is not the right call — you're buying this drive specifically because it runs 24/7, and the wear history of a renewed unit is unknown. Buy new here.

You'll need two of these for a RAID 1 mirror — one for each bay.
The Wi-Fi Problem: Why Your NAS Needs a Wired Connection
Even a fast NAS with well-configured drives will feel sluggish if the data travels over Wi-Fi. Wi-Fi introduces packet drops, signal interference, and variable latency — particularly during the large sustained transfers that define NAS workloads like pulling a database backup or syncing a container image.
The fix is straightforward: a physical Ethernet cable between your workstation and your NAS. If your main router is in another room or doesn't have enough ports, a small unmanaged network switch on your desk solves both problems simultaneously.
3. NETGEAR GS105 5-Port Gigabit Ethernet Switch — The Network Link
Amazon rating: 4.8/5 stars from 12,488 reviews — Overall Pick
The GS105 is the most reviewed and highest-rated small switch in this category by a wide margin, which reflects how widely it's used in exactly this kind of home lab and workspace setup.
It's unmanaged — meaning there's no configuration interface, no login, no setup. You plug in the cables and it works. Five Gigabit ports handle simultaneous local data transfers at full 1Gbps speeds, and the metal housing dissipates heat better than the plastic casing on cheaper alternatives.
In a typical desk setup, you run one cable from your main router to the switch, then individual cables from the switch to your workstation and your NAS. Local transfers between those two devices never touch your main internet connection at all — they go directly over the local network at full gigabit speed.
At 4.8 stars from over 12,000 reviews with an Overall Pick badge, this is one of the most straightforward buying decisions in this entire guide.

Automating Your Workspace Once the Hardware Is Running
With the enclosure configured, RAID 1 active, and a wired connection established, the useful work begins: automating the things you currently do manually.
Automated snapshots save the exact state of your system at scheduled intervals — hourly, daily, or weekly depending on how critical the data is. If a bad update breaks a local configuration, you roll back to the snapshot from two hours before rather than spending an afternoon reconstructing your environment.
Private Docker registry — the DS723+ can host a private container registry on your local network. Instead of pulling images from Docker Hub over your internet connection every time, your workstation pulls from the local NAS at gigabit speeds. In a team environment this is particularly useful — everyone pulls from the same local source rather than each person downloading from the internet independently.
Automated workspace backups can be scheduled to run at night, copying your active project directories to the NAS in the background without interrupting your work. Combined with RAID 1 mirroring, this gives you two independent layers of protection — a redundant drive and a versioned backup.
How This Fits Your Broader Setup
Local data infrastructure works alongside the rest of your workspace rather than replacing anything. See our guide on UPS and surge protection for home office setups for protecting this hardware during power instability, and our Terraform vs Ansible beginner's guide if you want to automate provisioning workflows that connect to this local infrastructure layer.
