In 2015, Huaqiangbei, a powerful company in China, launched a third-party iPhone upgrade storage service, which can upgrade the poor 16G storage to 64 and 128G for iPhone 6/6 Plus and other models. Although there was an upsurge of upgrading iPhone storage in China for a while, and Apple did not block this method officially, these machines can still upgrade the system normally.

Last year, GeekBar changed an iPhone 7 to 512G storage. On April 23, another foreign netizen manually upgraded the storage of iPhone 7 Plus to 512G and uploaded experience videos.

Theoretically, when other conditions are consistent, the larger the capacity of flash memory, the faster the speed. For this iPhone with doubled capacity, the continuous read speed of flash memory has not improved much, while the continuous write speed has increased from 340MB/s to 437MB/s, and the random read speed has slightly increased, but the random write speed has not changed significantly. However, compared with the iPhone 8 Plus, the continuous reading speed and random writing speed still lost.

In fact, the first official 512G flagship on the earth is designed by Huawei Mate RS Porsche. Before the release of iPhone X, everyone thought that there would be a 512G version of the Emperor, but Apple disappointed everyone. Otherwise, you might see the top iPhone with an extremely high price. In addition, the only thing that can be upgraded to 512G storage is the iPhone 7/7 Plus with A10 chip. The iPhone 8/8 Plus/X can also be upgraded to 512G theoretically, but there is no way to handle it for the time being.
