The M4 Mac mini is a huge upgrade from its predecessors in a lot of obvious ways, with a faster processor, a tiny form factor and 16GB RAM as standard. Now some teardowns are showing that it’s also improved on the inside.

On X, L0vertodream also posted on X a Mac mini teardown. L0vetodream states that “it is indeed a 1-slot dual-slot with a maximum particle size of 1TB. It uses a BGA315 hard disk and the maximum upgrade capacity can be up to 2T” [translated].

Before we get ahead of ourselves, it's worth pointing out that the Mac Studio (M2 Ultra) has a similar storage setup, but custom upgrades are difficult to do: the computer uses Apple 's own bespoke SSDs, you can't just slot in any off-the-shelf replacement.
