Multiply your monthly storage plan by thirty-six, then compare that total with the one-time price of a NAS plus the drives that go in it. That is the whole test. If the thirty-six-month figure is smaller, keep paying. If it is bigger, replace iCloud with NAS and stop renting space you could own.
The sum is worth re-running this month for two reasons. Immich, the self-hosted photo library most people run on a NAS, shipped v3.3.0 on 8 October 2026 — the project’s release page lists the version in full. Apple, meanwhile, still runs iCloud+ as a monthly plan, with the free tier stopping at five gigabytes.
Here is the part most guides skip. The arithmetic decides this, not enthusiasm. A small library on a free tier should stay put. A household where two people in different cities share folders daily should also stay put, because that is the job hosted services do well. Everyone else is usually paying for capacity they could have bought outright.
Key Takeaways
- The test is three years: a paid plan bills roughly thirty-six times in that window and never hands you hardware at the end of it.
- A two-bay unit with two 8-terabyte drives holds more than the tier most households pay for, and keeps serving files with no plan attached.
- The real running cost is a drive replacement, not electricity. Budget for one inside five years and the comparison stays honest.
- Migration is a weekend job, not a project — but only if you copy data first and cancel the plan last.
The Short Answer: Should You Replace iCloud With a NAS?
Yes — replace iCloud with NAS if you already pay monthly for capacity and your library keeps growing. No — if everything you own still sits inside a free allowance, or if shared albums with relatives in other countries are a weekly habit.
A NAS is a box with drives inside it, joined to your own network, holding files your household can reach from anywhere but which nobody else administers. Same access pattern as a cloud drive (reachable from anywhere), different owner (you).
The crossover arrives when your monthly plan stops being a rounding error. Add it up over three years. Then ask what the same money buys in drives — and remember those drives still exist at the end of year three, while the plan is a receipt.
Worked through with an example, it looks like this. Put your own monthly charge where the ten sits: at ten a month you are billed 360 across three years, and the hardware has to beat that figure. The plan side is the easy half to pin down, because Apple publishes every iCloud+ tier — read your own rate off that page rather than guess at it. On the hardware side a two-bay unit with two 8-terabyte drives is a one-time number, not a monthly one, and it keeps working afterwards. Both figures are illustrative: the plan price is yours to read, and the hardware price moves by market and by month, so treat the ten as arithmetic rather than a quote and swap in real numbers before you decide.
Why Does the Same Move Look Like a Bargain to One Household and a Waste to Another?
Because the two costs grow in opposite directions, and nobody tells you which curve you are on. A subscription prices capacity, and capacity is the one thing a photo habit never stops consuming. Hardware prices a fixed box, and the box does not care how many pictures you take next year.
Three patterns decide it:
- Library growth. A library adding real volume every month pushes the plan upward, and each upgrade resets the price. The box does not move.
- Who needs access. One household, one location, a handful of devices: local wins easily. Colleagues or relatives in three time zones: hosted wins, and that is not a defeat.
- How much admin you will tolerate. A NAS needs drives monitored and firmware updated. That is minutes a month. If that sounds like a burden, the subscription is the honest answer.
What Did We Actually Check?
Two things, both public, both linkable. First, the current release notes and feature list for Immich, because the photo library is the piece people worry about losing. Second, Apple’s own published plan structure, because the comparison only works against real tiers.
What we did not do is benchmark anything. There is no lab in this article and no measured throughput figure. Storage advice that invents test numbers is worth less than advice that shows its arithmetic, and our arithmetic is on this page for you to argue with.
Which Costs Show Up in Year Three That Nobody Mentions?
The ones that break the comparison are rarely on the invoice. Here is how the two options behave when you stop looking at the sticker.
| What you are comparing | A monthly storage plan | A NAS you own |
|---|---|---|
| How the bill behaves | Recurs every month, and rises when tiers change | Paid once; then electricity only |
| What happens when it fills | You buy the next tier, permanently | You add or swap a drive |
| Failure mode to plan for | Price changes and plan restructures | A drive dies; you replace it |
| What you hold at the end | A receipt | Hardware and your own files |
Two lines in that table deserve a warning. “You add or swap a drive” assumes you left a bay free — a two-bay unit with a mirrored pair is already full, and going bigger later means replacing both drives with larger ones. And “a drive dies” is not a scare story, it is a service interval. Treat the replacement as a scheduled cost and the three-year sum survives contact with reality.
The other hidden line is time. Moving a library is not hard, but it is not instant either, and the first sync of a large photo collection over home broadband takes longer than people expect. Start it before you cancel anything.
How Do You Move a Library Without Losing Anything?
The safe order matters more than the tools. Follow it and the worst case is having paid for one extra month.
- Export before you cancel. Download your originals from the provider while the plan is still active. Do not attempt a partial copy and top it up later.
- Set up storage first. Get the box running on the network and confirm a phone can see it. A two-bay unit covers most families — one drive for the library, one mirrored copy — while camera-heavy homes need more bays than that. If you want a named starting point, the A3 Lightweight Terminal is the compact family model we point people to, and we confirm bay count and drive compatibility against your own library before you order.
- Copy, then verify. Check the file count and a few dates against the original before touching the plan settings.
- Point the phones at the new library. Photo backup is a per-device setting, and it is the step people forget on the second phone.
- Cancel last. Keep the plan for one more month as a fallback, then close it deliberately.
Most of the effort sits in step one, and there is no way around it. Downloads from a large library are slow because they are large.

Where Do Migrations Go Wrong?
Three mistakes account for almost every bad experience, and all three are avoidable.
Cancelling first to “force the move”. It does not speed anything up. It removes your fallback on the day something fails, and it turns a routine copy into a rescue.
Sizing for today’s library. Whatever you have now will not be what you have in two years. Buy for the current library plus one growth step, not for an imaginary archive.
Forgetting the second device. The main phone gets configured; the tablet and the partner’s phone quietly keep uploading to a plan you thought you had closed.
Five things are worth confirming with whoever supplies the hardware before you order, because each one changes the price or the plan: how many bays the unit has now and whether any stay free for later; which RAID level you will run, since mirroring halves usable capacity; whether your chosen drive models sit on the vendor’s compatibility list; how phones and laptops reach the box from outside the house; and what the warranty actually covers — the enclosure, the drives, or both.
Our Take: When I Would Stay on the Plan
If it were my money, I would move a growing family library and I would skip the move for a small one. That is the plain version. The cases against moving are not close. A tiny collection does not justify a device that wants the odd firmware update (a few minutes a month), and anyone whose work runs on shared folders across several countries is better served by a hosted plan at that specific job.
The counter-intuitive part is where the money sits. People assume the savings come from the drive purchase. They mostly come from breaking the upgrade ladder — every time your library grows, a plan charges you again for capacity, while a box charges you once and then asks only for a replacement drive years later. The NAS storage range is built around that idea: pay once, own the hardware, no plan attached.
There is one more case worth naming, because it is where this decision usually starts. If the same house is also recording security cameras, the storage maths changes shape entirely — camera footage is continuous, bulky and the data people least want on someone else’s servers. A camera and storage setup sized once tends to beat two separate monthly bills, which is why so many households end up here through the camera door rather than the photo door.
What We Don’t Know
We cannot tell you which drive is best value in your market this quarter, and we are not going to guess: drive pricing moves constantly and a figure written today would be wrong by the time you read it. We also cannot promise a rebuild time for your specific capacity — rebuild duration depends on the drives, the RAID level and how much data is on them, and any site quoting a single number for all of that is quoting an average that will not be yours. The substitution is straightforward. Ask your supplier four questions instead: price per terabyte today, whether the drive is rated for continuous NAS use, the warranty length and what it covers, and how long a rebuild takes at your capacity. Those four answers turn a guess into a specification.
Frequently Asked Questions
Should I replace iCloud with NAS for photos alone?
For a growing library on a paid tier, usually yes — the recurring fee is what you are replacing, not the convenience. For a collection that still fits in a free tier, no. Run the thirty-six-month sum with your own numbers before buying anything.
How much capacity do I need if I replace iCloud with a NAS?
Match the tier you pay for now, then add headroom. A family archive commonly starts in the low single-digit terabytes, and a two-bay unit holding two 8-terabyte drives gives you more room than the tier most households actually pay for — with room to grow, though mirroring halves the usable figure.
Can I replace iCloud with a NAS if I am not technical?
Yes, with one honest caveat. Setup is appliance-simple: plug it into the router, run setup in a browser, install the phone apps. The ongoing work is small but real — watch drive health and take the occasional firmware update, a few minutes a month. The genuinely technical decision is how many bays and which RAID level, and that is a sizing conversation you can have before you order.
What happens to my files if the NAS fails?
They stay on the drives rather than vanishing, which is the point of owning them. A failed drive in a mirrored pair is replaced without losing data; a failed box usually means moving the drives to a compatible unit. Off-site copies are still your responsibility.
If you want the comparison run against your actual library rather than a general rule, tell us how much you store now, how fast it is growing and whether cameras share the same box. We size the configuration and come back with a quote within 24 hours — no account needed, just the numbers.
