More memory or storage in an M1? Q When I choose my new M1 Mac, should I get more memory or a bigger SSD? by RODDY MARTIN

A Apple silicon models come with special high-speed memory mounted in the M1 chip carrier which can’t be upgraded or replaced, and their internal storage is soldered in, again for performance and security. While you can always add external storage, it’s essential to get both right when you order.

M1 Macs use memory differently from Intel models. They don’t have any graphics memory, as all parts of the chip including the GPU share main memory to deliver the best performance. This doesn’t mean that you have to add on an allowance for graphics use, like the dedicated memory in graphics cards, as they use memory much more efficiently. But you do want to avoid them using ‘swap’ space in storage. For most users, 16GB is a good minimum, rising with your need for more heavyweight apps.

Although it’s possible to put your Home folder on external storage, and some external SSDs make claims of speeds approaching those of M1 internal SSDs, unless they have active cooling systems with fans they’ll undergo thermal throttling when used hard.

Apple’s pricing may seem high, but its SSDs are high performance, and larger SSDs not only perform better but last longer too. What you save by skimping on internal storage could increase wear and shorten life, as well as being more work to manage. For most users, a minimum of 1TB is a good starting point.
