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.
Results: SSD Peak Speed
Tested with the run-sequential command of diglloydTools DiskTester.
Versus the 2019 iMac 5K, the 2019 MacBook Pro SSD is esssentially the same speed for writes, but about 10% faster for reads.
This performance ranks right up with the best for peak transfer speed, but see the speed vs transfer size graph.
These are real world figures through the OS X file system APIs, and thus reflect the performance available to applications.
