New 256GB Mac Mini and 512GB MacBook Pro Have Slower SSD Speeds Than Previous Models
Recent evaluations reveal that the new Mac mini with 256GB storage and 512GB MacBook Pro feature slower SSD read and write speeds than earlier models like the M1. A teardown indicates the new 256GB model uses a single NAND chip, which significantly reduces performance, leading to speeds 30% to 50% slower. Users eyeing rapid file transfers are encouraged to select configurations of at least 512GB to ensure optimal performance. This trend indicates a concern regarding Apple’s SSD configurations in their latest products, as it could affect overall system efficiency under certain workloads.
