When Apple announced Fusion Drive, we expected it to be quick. But TLDToday has performed some speed tests, comparing a new Mac mini to its predecessor, and the results are pretty amazing.
Despite the fact that the new Fusion Drive uses a 5,400rpm hard disk as its bulk storage, it doesn't seem to hold things back. Boot times are half what they used to be—perhaps not too surprising as the OS is almost certainly installed on the SSD—but copying files is just so. Much. Quicker.
