Apple has reintroduced modular storage to its latest Mac mini lineup, allowing customers to upgrade individual components rather than replacing the entire unit. The new base model features two 128GB NAND chips, which enables faster SSD read and write speeds compared to a single 256GB chip used in previous models. This change is particularly notable in configurations with higher-capacity storage options.
The modular design allows for easier removal of the storage components, but replacing them can be complicated as seen in the Mac Studio. The move away from a single 256GB chip improves performance and satisfies customers who prioritize speed over storage capacity.
The revised design comes after criticism received by Apple regarding its use of a single 256GB chip in some base models. However, with the new configuration, customers who opt for the highest storage capacities will not notice significant differences in everyday tasks. This update provides flexibility for users seeking faster SSD speeds without compromising on storage options.
