ETA: I have reformatted the new Samsung T5 to APFS. As always the test file was a 1.07GB .mov video file created using a command line in the Terminal app on my MacBook Pro. However, I also included the results from the Blackmagicdesign app and the ATTO Disk Benchmark app for the MacBook Pro speeds. Here are the results from the APFS and ExFAT tests. The WRITE speed using the iPad Air 2020 was significantly increased, but the other tests were about what they were with ExFAT.
IPad Air 4 with Samsung T5 2TB USB-C 3.1 Gen 2 External SSD Drive (APFS format)- READ speed = 195 MB/s
- WRITE speed = 195 MB/s
IPad Air 4 with Samsung T5 2TB USB-C 3.1 Gen 2 External SSD Drive (ExFAT format)- READ speed = 214 MB/s
- WRITE speed = 134 MB/s
MacBook Pro with Samsung T5 2TB USB-C 3.1 Gen 2 External SSD Drive (APFS format)- READ speed = 357 MB/s
- WRITE speed = 357 MB/s
- Blackmagicdesign: READ = 426 MB/s
- Blackmagicdesign: WRITE = 417 MB/s
- ATTO Disk Benchmark: READ speed = 419 MB/s
- ATTO Disk Benchmark: WRITE speed = 435 MB/s
MacBook Pro with Samsung T5 2TB USB-C 3.1 Gen 2 External SSD Drive (ExFAT format)- READ speed = 357 MB/s
- WRITE speed = 356 MB/s
- Blackmagicdesign: READ = 421 MB/s
- Blackmagicdesign: WRITE = 418 MB/s
- ATTO Disk Benchmark: READ speed = 419 MB/s
- ATTO Disk Benchmark: WRITE speed = 435 MB/s
