Slow write TB3 EVO+ speed on iMac 2019 i9 vs 2018 MBP i7
What is the reason that the write speed with a TB3 Orico TCM2T3-G40 enclosure with a Samsung 970 EVO Plus 1TB installed is much slower on 2019 27” iMac i9 8 core (64GB, 2TB SATA SAMSUNG SSD, 128GB Blade SSD) than 2018 15” MacBook Pro i7, 6core, 32GB?
- MacBook Pro: Write: 2200MB/s, Read 2550MB/s
- iMac Write only 850MB/s, Read: 2500MB/s
Tried with APFS and EXFAT too - with same results.
