iPhone Air restricts third-party storage expansion! Technology Up master successfully breaks through the limit

　　Overy pursuit of thin and thin design is often accompanied by technological compromise. According to reports, Apple has imposed restrictions on the expansion of third-party storage capacity of iPhone Air. It is still unclear whether the policy will be extended to the iPhone 17 series.

　　Up owner "Director Feng Mobile Phone Repair" has tried to expand the capacity of the iPhone Air by welding and upgrade 256GB of storage to 512GB or 1TB. However, when flashing into the iOS system, the device cannot recognize the new capacity; replacing another 256GB module still encounters the same failure. In the early stage, it was speculated that it might be that Apple used the inventory components of Yangtze Storage, which has withdrawn from Apple's supply chain, resulting in abnormal system compatibility.

　　But the blogger later updated and stated that the core crux of the failure of capacity expansion is the compatibility of high-speed hard disks - the 256GB/512GB/1TB NAND equipped with iPhone Air are all high-speed hard disk types, while most of the circulating on the market are low-speed hard disks. After many tests, he finally found an adapted high-speed NAND hard drive from a supplier. The actual test score of Antutu storage reached 153,000 points, far exceeding the performance of the original hard drive, and the capacity expansion can be completed without modifying the motherboard layering, perfectly solving the compatibility problem.

This technological exploration reveals the hidden limitations of ultra-thin models in hardware design, and also shows the innovative potential of third-party repairs to break through official restrictions.
