Raspberry Pi firmware since 2024 locks down RAM upgrades by validating module compatibility, preventing users from installing different RAM sizes or manufacturers. While designed to prevent incompatible changes, this restriction frustrates users who expect upgradeability on open-source hardware, contrasting with policies on other devices like GPUs and Apple computers.
Apple's new Mac mini models with M6 and M5 Pro chips have soldered, non-upgradeable storage, reversing the removable SSD capability of M4/M4 Pro models. Additionally, 256GB configurations use a single NAND chip resulting in roughly half the SSD speeds of higher-capacity models, though still faster than previous generations.
Apple's new M6 and M5 Pro Mac mini models return to soldered NAND storage, eliminating the upgrade capability that was available in M4/M4 Pro models. Additionally, 256GB configurations use a single NAND chip, resulting in slower SSD speeds compared to 512GB+ models, though still faster than previous generations.
