For an extended period, Apple has been known to charge a substantial premium for storage and memory upgrades on its devices. This pricing strategy leaves users, who lack the soldering expertise to handle NAND storage modules, with no option for independent upgrades. The latest video disclosure highlights that storage expansion for the iPhone Air is severely restricted. New chips of various capacities fail to be recognized during the iOS system refresh process. One video uploader made an attempt to upgrade the iPhone Air's ROM storage from 256GB to both 512GB and 1TB. However, the iOS system failed to recognize these chips during the flashing process. Interestingly, even another 256GB module went unrecognized. The uploader speculated that these NAND modules might not have originated from common suppliers. Instead, they could have been sourced from Yangtze Memory Technologies' inventory, a company that is no longer part of Apple's supply chain. Ultimately, the uploader managed to find a high-speed NAND hard drive that is fully compatible with the iPhone Air. This drive not only works seamlessly but also delivers benchmark scores that significantly outperform those of the original hard drive. The expansion can be achieved without the need for motherboard modifications. Currently, the expansion supports up to 512GB, but the possibility of offering 1TB options in the future has not been ruled out.
