New Mac Mini Has Modular Storage, 256GB Model Will Have Faster SSD

Apple has returned to using two 128GB storage chips in the new Mac mini with 256GB of storage, according to a partial teardown video shared on social media today. This means the base-model Mac mini with the M4 chip will not have significantly slower SSD speeds compared to higher-end configurations of the computer with 512GB, 1TB, or 2TB of storage, as multiple NAND chips allows for faster SSD read and write speeds.

The teardown video also reveals that storage is modular in the new Mac mini, meaning that it can be easily removed since it is not soldered down. As we saw with the Mac Studio, however, replacing the modular storage is complicated.

The previous-generation Mac mini base model with the M2 chip has a single 256GB storage chip, resulting in 30% to 50% slower SSD read and write speeds compared to higher-capacity models. The slower speeds led to criticism from some customers.

Apple returned to using two 128GB storage chips in 256GB configurations of MacBook Air models with the M3 chip earlier this year, while the 13-inch MacBook Pro line was discontinued last year and replaced with an entry-level 14-inch MacBook Pro that starts with 512GB of storage.
