How much RAM and storage you actually need in 2026
Windows 11 will install on 4 GB of memory and a 64 GB drive. Both of those numbers describe a computer that boots, not a computer you would want to use — and on most laptops sold today, you only get to choose once.
There are two numbers on a laptop listing that decide how the machine will feel in three years, and neither of them is the processor. Memory determines how much you can have open before everything gets sticky. Storage determines whether you spend your Sundays deleting things.
Both are now soldered on most thin laptops and fixed for life on every phone. The decision you make at checkout is the decision you live with.

The short answer
| What you do | Memory | Storage |
|---|---|---|
| Browsing, email, streaming, documents | 16 GB | 512 GB |
| Office work with many tabs and video calls | 16 GB | 512 GB–1 TB |
| Photo editing, light video, design | 32 GB | 1 TB |
| Software development, virtual machines | 32 GB | 1 TB |
| Serious video work, 3D, local AI models | 48–64 GB | 2 TB |
| A second machine that only browses | 8 GB (grudgingly) | 256 GB |
If one line matters more than the rest: 16 GB is the floor for a main computer in 2026, and 8 GB is a machine you will replace early. Memory is also the cheaper of the two to overspend on relative to the regret.
Why official minimums mislead
Microsoft's published system requirements for Windows 11 are 4 GB of RAM, a 64 GB or larger storage device, a 1 GHz processor with two or more cores, TPM 2.0 and UEFI with Secure Boot. Those are real numbers, and they are genuinely the point at which the operating system will install and run.
They are also a compatibility floor written for manufacturers, not shopping advice. A minimum specification answers "will this boot", never "will this be pleasant in year three, with a browser open".
Apple made the opposite argument with hardware rather than documentation. In late 2024 it doubled the base memory across the MacBook Air line to 16 GB at the same price, quietly ending the 8 GB era for new Macs. When the company with the most control over its own software stack decides 8 GB is no longer a sensible starting point, that is a useful signal.
What actually eats memory
People imagine memory is consumed by big applications. Mostly it is consumed by many medium ones, and by the browser above all.
- Browser tabs. A modern browser isolates each site in its own process for security. That is the right design and it costs memory per tab, especially on sites running heavy scripts.
- Chat and productivity apps. Slack, Teams, Discord, Notion, Spotify and many others each bundle their own browser engine. Four such apps is four browsers running at once.
- Video calls. Encoding, decoding and background blur together are one of the heaviest things an ordinary laptop does.
- On-device AI features. Assistants and image tools that run locally hold models in memory while active — a genuinely new line item compared with a few years ago.
- The operating system's own cache. Free memory is wasted memory, so the OS fills it. High "memory used" is normal; sustained swapping to disk is the symptom that matters.
The number to watch is not "memory used"
On Windows, open Task Manager and look at the disk activity when things feel slow. On a Mac, look at Memory Pressure in Activity Monitor rather than the memory total: green is fine no matter how full it looks, and persistent yellow or red means the machine is short.
Macs and unified memory
Apple silicon uses one pool of memory shared by the processor and the graphics unit, which is why the spec sheet says "unified memory" rather than RAM. It is genuinely more efficient — data does not have to be copied between separate pools — but it also means anything graphical draws from the same 16 GB or 32 GB your applications are using.
The practical consequence is that memory on a Mac is doing more jobs than the equivalent number on a PC with a discrete graphics card, and it cannot be upgraded afterwards under any circumstances. Buy the tier above the one you think you need if the price difference is bearable.

The storage number you actually get
A "1 TB" drive is one trillion bytes, and operating systems count in binary units, so the same drive reports as roughly 931 GB before anything is installed. Nothing dishonest is happening — the two systems simply count differently — but it means the usable figure is around 7 % below the number you paid for, and that is before the operating system, recovery partition and applications take their share.
Why a nearly-full SSD gets slow
This is the part that surprises people, because hard drives did not behave this way. An SSD cannot overwrite data in place; it writes to empty blocks and erases old ones in the background. It also uses a portion of unused space as a fast write cache, and spreads writes evenly across the chips to make them last.
All three of those need spare room. As a drive approaches full, the controller has fewer free blocks to work with, the fast cache shrinks, and write speed can fall dramatically — on a drive that tested beautifully when it was new.
Keep 10–20 % free
Not as a superstition — as the working space the drive needs. If you routinely run a 512 GB drive at 490 GB used, you do not have a slow computer. You have a drive with nowhere to put things.
Soldered versus upgradeable
Thin laptops overwhelmingly solder their memory to the board, and many now solder the storage too. Some manufacturers use the newer compression-attached memory modules that can be replaced by a technician, but that is the exception rather than the rule, and it is never the cheap tier.
So the sequence to follow when buying is:
- Find out whether memory and storage are upgradeable on the exact model — not the product line. Configurations differ.
- If they are soldered, buy one tier above your estimate. The upgrade at checkout is expensive; the upgrade later is impossible.
- If they are upgradeable, buy the base and upgrade yourself. Manufacturer memory pricing is typically several times the retail price of the same module.
- Prefer more memory over a faster processor if you have to choose. Running out of memory slows everything; a slightly slower processor slows one thing at a time.
- Use external storage for archives. Adding a portable drive is easy; adding internal storage to a sealed laptop is not.
Phones are a different calculation
Phone memory is not something you choose or manage — the manufacturer sizes it and the operating system decides which apps stay resident. The symptom of too little is not an error message but apps reloading from scratch when you switch back to them.
Storage is the one you do choose, and it is fixed forever, since almost no flagship still takes a memory card. The practical guidance:
- 128 GB works only if your photos live in the cloud and you accept that.
- 256 GB is the sensible default for most people keeping several years of photos and video.
- 512 GB and above is for people who shoot a lot of video, keep offline music and maps, or simply refuse to manage storage — a legitimate reason to spend money.
The cost of getting this wrong is not really the inconvenience. It is that a phone or laptop that ran out of room gets replaced early, which is by far the most expensive way to buy storage.
