Apple is poised to introduce the ASIF disk image format in the upcoming macOS 26 Tahoe system. This innovative format dramatically enhances disk image read and write speeds, closely rivaling the performance of native SSDs. In rigorous tests, the MacBook Pro powered by the M3 Pro demonstrated remarkable read speeds of 4.8GB/s and write speeds of 4.6GB/s, even with encryption enabled. The ASIF format not only accelerates performance but also optimizes disk space utilization. However, the creation and modification of ASIF images are currently exclusive to macOS 26 and involve a somewhat intricate process.
