The bottom mannequin of Apple’s latest Mac mini and the 2023 MacBook Professional have has considerably slower SSD learn and write speeds due to engineering selections, in comparison with that of the earlier era fashions.
A teardown by Brandon Geekbit has uncovered the rationale on the Mac mini — the 256GB Mac mini comes with a single 256GB storage chip. Final era’s M1 Mac mini got here geared up with two 128GB flash chips in parallel, permitting for quicker speeds.
Because it seems, the 512GB M2 Mac mini additionally includes a single NAND chip, which means that it might nonetheless have slower learn/write speeds than a mannequin with two 256GB chips. Nonetheless, as there was no 512GB Mac mini with an M1 Professional chip, there is not any comparability to be made.
The scenario is analogous on the 2023 MacBook Professional as effectively, as found by 9to5 Mac. The decrease storage capability fashions have fewer Flash chips at a better density than the earlier mannequin. This cuts down velocity versus what it might be, versus what you get from parallelization of a number of flash chips.
