Do You Need a NAS at Home in 2026?

Short version: most people don't need a NAS, and the ones who do usually figured it out the hard way after a drive died or a Google One bill crossed $200 a year.

I've run one in a closet since 2019. It has saved me twice and annoyed me roughly a dozen times. That's the honest ratio nobody puts in the vendor blog posts.

So before you spend $400 on a box plus another $300 on drives, here's the decision, laid out the way I'd explain it to a friend.

What a NAS Actually Is

It's a small, always-on computer with two or more hard drive bays and an ethernet port. It sits on your network, runs its own operating system, and every device in the house can read and write to it.

That's it. No magic. The reason it costs more than an external drive is that you're buying a computer, not a container for spinning platters.

The Three Questions That Decide It

1. How much data do you have, and is it growing?

Under 2TB and flat? Cloud storage wins on price and hassle. Google One gives you 2TB for about $10 a month, and it's offsite, encrypted, and somebody else's problem when a drive fails.

Above 4TB and climbing, the math flips. A 2-bay box with two 8TB drives runs roughly $700 all in, and that's a one-time cost against $240 a year in cloud fees for the same capacity. Break-even lands around year three.

2. Is it more than one person, or more than one device?

This is the question that actually matters, and it's the one everybody skips.

A NAS earns its keep when four laptops, two phones and a TV all point at the same storage. Automatic phone photo backup for the whole family, Time Machine targets for the Macs, one media library instead of four copies of the same movie. If you're a single person with one laptop, an external drive plus a cloud sync folder covers you for a fraction of the price.

3. Will you maintain it?

A NAS is a computer that lives on your network forever. It gets firmware updates, drives eventually fail, and if you expose it to the internet carelessly it becomes somebody's ransomware target.

If "I'll deal with it later" is your default with tech chores, buy the external drive. Seriously. An unmaintained NAS is worse than no NAS because you'll trust it with data it isn't protecting.

When an External Drive Is Genuinely Enough

You can skip the whole category if this sounds like you.

• One computer, one user, and backups you actually run
• Under 2TB of stuff you'd cry about losing
• No interest in remote access to your files
• You already pay for cloud storage and you're fine with it

For that person, a fast external SSD and a scheduled backup is the correct answer. Our external SSD picks cover that route and it'll cost you under $200.

When You Should Actually Buy One

These are the cases where I've seen a NAS pay for itself.

• Plex or Jellyfin. A real media library on a box that transcodes is the single most common reason people buy in, and it's a good one.
• Photo and video work. If you shoot RAW or edit 4K, you generate terabytes a year and you need versioned storage, not a drawer full of drives.
• Family photo backup. Every phone in the house backing up to your own hardware, no subscription, no scanning.
• Home lab. Docker containers, Home Assistant, a Pi-hole, an ad-free DNS setup. The modern NAS runs all of it.
• You've already lost data once. Nothing motivates like a dead drive.

RAID Is Not a Backup

I need to say this loudly because half the people buying a 2-bay NAS think they're done once it's mirrored.

RAID protects against a drive failing. It does nothing about ransomware, accidental deletion, a bad power supply cooking both drives, or your house flooding. Delete a file on a mirrored array and it's gone from both drives instantly.

The rule is 3-2-1. Three copies, two different media, one offsite. A NAS is one leg of that, not all three. Budget for a cloud backup tier on top, something like Backblaze B2 at roughly $6 per TB per month, or a rotating external drive you keep at work.

What It Costs to Run

Nobody mentions the power bill.

A 2-bay unit with spinning drives pulls around 25W to 35W in normal use. At 30W continuous and $0.15 per kWh, that's about $39 a year. Not scary, but it's not zero, and a 4-bay box with four drives roughly doubles it.

Noise is the other tax. Hard drives clatter when they seek. If the box lives in your bedroom you'll hear it, which is why mine lives in a closet with a piece of foam under it.

The Boxes Worth Buying

Two recommendations, because there are really only two shapes of this problem: "I want a private cloud and a Plex server" and "I do real work with big files."

Both ship diskless. Add drives to whatever you see above.

UGREEN NASync DXP2800

The N100 is the reason to buy this. It's the same chip in every cheap mini PC right now, and its QuickSync engine chews through 4K HEVC transcodes that would strangle an ARM NAS. Plex, Jellyfin, a few Docker containers, all fine.

UGOS Pro is the tradeoff. It's gotten a lot better over the past two years, and for backup plus media plus Docker it's genuinely fine now. But it's not DSM. If you want the most polished software on the market you want a Synology, and you'll pay more for less hardware to get it.

Worth knowing: Synology spent most of 2025 restricting third-party drives on its newest Plus models, then reversed course with DSM 7.3 and restored support for standard WD and Seagate drives. Older units like the DS224+ were never affected. The episode cost them a lot of goodwill anyway, and it's part of why UGREEN is suddenly everywhere in home lab threads.

TERRAMASTER F4-424 Pro

This is the one you buy when the 2-bay isn't the answer. Eight cores and 32GB of RAM is not NAS hardware in the traditional sense, it's a small server that happens to hold four drives.

Four bays also changes the storage math. With RAID 5 across four 8TB drives you get 24TB usable and survive one failure, versus 8TB usable on a mirrored 2-bay. If you're editing video off the box, that plus dual 2.5GbE is the difference between working from the NAS and copying files back and forth all day.

TOS is the weak point. It works, it's stable enough, but it feels a generation behind DSM and the mobile apps are basic. Plenty of people buy TerraMaster hardware and immediately install TrueNAS or Unraid on it, which tells you something about both the hardware value and the software.

Buying Guide

How many bays do you need?

Two bays gives you a mirror, which means one drive can die. That's the minimum I'd accept. Four bays gives you RAID 5, better capacity efficiency, and room to grow without rebuilding everything.

Buy for where you'll be in three years, not today. Migrating a full array is a weekend you won't enjoy.

Do you need Intel for Plex?

If you plan to transcode, yes. Intel's QuickSync does hardware-accelerated transcoding that a low-power ARM chip simply can't match.

If everything you watch plays natively on your TV and phone, called direct play, the CPU barely matters. Most modern TVs handle HEVC fine, so a lot of people never transcode at all. Worth checking before you pay for the faster chip.

Budget for drives separately

Nearly every NAS on Amazon ships diskless, and drives are usually the bigger line item. Two 8TB NAS-rated drives run about $300 to $360 depending on the week.

Use drives built for this. Desktop drives lack the vibration handling and firmware behavior arrays want, and they fail earlier in a multi-drive chassis. Our NAS drive picks go deeper on which models are worth it.

Does 2.5GbE matter?

A single spinning drive tops out around 150MB/s to 200MB/s, and gigabit ethernet caps you at roughly 110MB/s. So yes, on a multi-drive array you will feel the limit.

The catch: your router or switch has to support it too. If your whole network is gigabit, the faster NAS port does nothing until you upgrade the switch.

What about just building one?

An old desktop plus TrueNAS is cheaper and more flexible. It's also louder, bigger, less power efficient and entirely your problem when something breaks at 11pm.

I've done both. The appliance wins for anyone who wants storage rather than a hobby.

Frequently asked questions

Is a NAS worth it compared to cloud storage?

Above about 4TB, yes. A 2-bay box with two 8TB drives costs roughly $700 once, against around $240 a year for equivalent cloud capacity, so it pays back near year three. Under 2TB, cloud storage is cheaper and simpler.

Can I use a NAS as a Plex server?

Yes, and it's the most common reason people buy one. You want an Intel CPU with QuickSync, like the N100 in the UGREEN DXP2800, if you plan to transcode. If your devices direct play everything, almost any modern NAS handles it.

Does RAID mean I don't need backups?

No. RAID only survives a drive failure. It does not protect against ransomware, accidental deletion, power surges or theft. Keep a second copy somewhere else, ideally offsite, on top of the array.

How much power does a home NAS use?

A 2-bay unit with spinning drives averages 25W to 35W, which is about $39 a year at $0.15 per kWh. A 4-bay box with four drives roughly doubles that.

Do NAS units come with hard drives?

Usually not. Both units here ship diskless, so budget another $300 or so for two 8TB NAS-rated drives. Some bundles include drives at a small premium.

Is a NAS hard to set up?

The first hour is easy. Install drives, run the web setup wizard, create a storage pool and a shared folder. The parts that take longer are remote access, backup scheduling and Docker, and those are optional on day one.

The Bottom Line

If you're one person with one laptop and under 2TB of files, buy an external drive and a cloud subscription and stop reading buying guides. You'll save $600 and a lot of evenings.

If there are multiple people, multiple devices, a growing media library, or work files you can't lose, a NAS is a genuinely good purchase. Start with the UGREEN NASync DXP2800 at $369.99, since the N100 covers Plex and containers and two bays is enough for most homes. Step up to the TERRAMASTER F4-424 Pro only if you're editing video off the array or running virtual machines.

And whatever you buy, set up a second copy of anything that matters. The array is not the backup. If you want more options, our full home NAS roundup covers the rest of the field.
