I have bought a Mac studio M1 max with 32 GB RAM and 512 GB SSD.
When copying 900 GB from one USB-disc to another it says it takes about 4 hours.. Why is this?
I use Mac OS Monterey 12.2
Mac Studio, macOS 12.2

The drives are Western digital passports with usb C and A connections (but should be 5-10 Gb/s due to USB 3.0). They are way quicker on my MacAir laptop (ca. 5 years old)… I think this is strange
The USB disks themselves are probably the bottleneck.
If they support only USB2, it will be slow, no matter which mac you use.
What are the drives, and also how are they formatted?
Some people have reported poor drive performance associated with formats like ExFAT on Ventura.
I have always formatted my disks «Mac os x extended». This has always been working well on my 5K Retina 27-inch late 2014
There are many fixes between Monterey 12.2 and 12.6.2 that maybe associated with this slow usb drives
Why so slow speed when copying on a new mac studio
