Sequential transfer speed is the most critical metric for applications that work with large files. It also translates directly to performance elsewhere. However, transfers of smaller sizes can be critically important for some tasks so this is far from the only metric.
Tested with the run-sequential command of diglloydTools DiskTester.
Versus the 2017 iMac 5K, the 2018 Mac mini SSD is a little faster on read speed, and about 30% faster on writes. This helps explain the superior performance on the diglloydHuge benchmark.
These are real world figures through the OS X file system APIs, and thus reflect the performance available to applications.
