How much storage do you need in a MacBook Pro?

Take 1TB if your work is documents, browsing, photos and the odd video, and 2TB if you edit video, keep a large photo library or work in big project folders. Go beyond that only when you can name the files that need it. The choice is easier than it used to be: 1TB is now the smallest drive in every current mini-LED MacBook Pro, and the M5 Max starts at 2TB.

Unlike memory, storage has an escape route. A fast external drive over Thunderbolt adds space with a cable, not a new Mac. So the target is enough room for the files you work on every day, not for everything you will ever keep.

What each MacBook Pro offers

From Apple's tech specs pages:

On the 14-inch M5 Pro, Apple's page lists 1TB or 2TB as standard depending on the configuration, while the 16-inch M5 Pro starts at 1TB. The 8TB option is only on M5 Max.

Apple counts 1TB as one trillion bytes and notes that the formatted capacity is less, and macOS itself takes a share. Plan on a little less room than the number on the order page.

Choose the internal drive with the same care as memory: Apple offers the sizes when you configure the Mac, so plan as if that is your one chance. How much RAM you need in a MacBook Pro covers the other number to get right at the start.

Why the internal drive is worth having

Apple says the SSD in the M5 Pro and M5 Max MacBook Pro reaches read and write speeds of up to 14.5GB/s, which it puts at up to twice the previous generation. Its test used a 16-inch M5 Max with an 8TB drive, so read that as the top of the range. For the M6 model, Apple calls the storage superfast but gives no figure.

That speed is the reason to keep your current projects inside the Mac and move archives out. The files you open every hour benefit most from the fastest drive you have.

What actually fills a drive

Most people have a feel for what is big on their Mac. A few things are bigger than they feel.

• Video. Footage is the largest thing most people keep. One project with high-resolution clips, proxies and exports can take a large share of a 1TB drive.
• Photos. A library built up over years is large, and raw files are larger still.
• Apps and their data. Creative and development tools keep caches, libraries and downloaded components that build up quietly.
• Virtual machines and containers. Each virtual machine is a file the size of a whole operating system, plus whatever you install in it.
• Local AI models. Models are big files, and people tend to download several to compare.
• Messages, mail and phone backups. Years of attachments, and old iPhone or iPad backups, add up more than anyone expects.

To see where yours has gone, choose Apple menu > System Settings, click General, then click Storage. The breakdown by category is the quickest way to learn whether you are a documents person or a video person, and Apple's own store suggests the same check before you pick a size.

A simple way to choose

1. Documents, browsing, email, streaming, some photos: 1TB. Enough for years, and the smallest drive on any current model.
2. Photographers, light video editing, developers with several projects: 1TB to 2TB. If you already keep archives on an external drive, 1TB is enough. If you want everything on the Mac, take 2TB.
3. Video editors, music producers with big sample libraries, anyone running virtual machines: 2TB to 4TB. This is where the M5 Pro and M5 Max configurations fit, and where the fast internal drive pays off every day.
4. Heavy work above 4K, large local models, big archives you must carry: 4TB to 8TB. Make sure an external drive would not do the job first.

External drives do more than people think

Every M5 Pro and M5 Max model has three Thunderbolt 5 ports, rated by Apple at up to 120Gb/s. The M6 model has three Thunderbolt 4 ports at up to 40Gb/s. Either way, an external SSD can hold an archive, a library of finished projects or the footage for a current job.

That makes a plan like this sensible: enough internal storage for the system, your apps and the projects in progress, and the rest on a drive that stays on the desk. Thunderbolt 5 vs Thunderbolt 4 on the MacBook Pro explains when the faster ports make a difference.

Two cautions. An external drive is one more thing that can be lost or fail, so keep a second copy of what matters, with Time Machine or another drive. And if you travel and need the whole archive on the road, an external drive is one more thing in the bag, which is a fair reason to buy more inside.

Where iCloud fits

In General > Storage, Apple's Store in iCloud recommendation keeps your Desktop and Documents folders in iCloud Drive, your photos and videos in iCloud Photos and your messages in iCloud. When space runs short, the Mac then keeps only recently opened files on the drive.

That helps a lot with documents and photos, and not at all with video projects or local models, which need to sit on a fast drive. It also depends on your connection and on how much iCloud storage you have. Treat iCloud as a way to stretch a drive by a margin, not as a reason to buy a much smaller one.

Keeping a drive from filling up

A nearly full startup disk causes trouble before it stops you saving. Apple's own advice for a full disk starts with not having room to download, install or copy, and a macOS update needs room to install. Leave yourself a margin.

• Open General > Storage every few months, and use the More Info button next to a category to see what is inside it.
• Turn on Empty Trash Automatically there, which erases items that have been in the Trash for more than 30 days.
• Clear out the Downloads folder and old iPhone or iPad backups you no longer need.
• Move finished projects to an external drive, and keep a second copy.

Notchpals can keep an eye on this from the notch, which every MacBook Pro in this post has. Once less than 10 percent of the startup disk is left, a Tech care character such as Juice, the battery who faints dramatically, says so, at most once a week. Notchpals reads only how much space is left, never what your files are.

JuiceYour disk is a crowded stage. Send the extras home. Old files first.

Then open General > Storage and start with the largest category. That is usually where the space went.
