Hello WD Community,
I purchased the WD My Passport Ultra 5 TB drive. it cam pre-formatted for windows. I reformatted it to APFS in Disk Utility.
The drive works great – I’m trying to understand how fast it SHOULD run…
I want to use my M1 Mac Mini’s Thunderbolt port for maximum speed.
The Blackmagic Disk Speed Test app shows 120 MB/sec read and write speeds on my new 2020 M1 Mac Mini on USB 3.0. I was unable to connect the drive to the Mac’s Thunderbolt port with the included cable. After buying a USB-C Thunderbolt 3 cable on Amazon , I STILL see 120 MB/sec read and write speeds using the Thunderbolt ports.
Is this the expected speed of he drive? I have tried asking WD Support directly via email, but they have only provided “theoretical” max USB speeds, which is not what I am asking.
This is the USB-C cable I purchased on Amazon. The cable works, but is this the best speed I should expect??

I’ve never had any problems with any WD My Passport drives I’ve owned, so I’m happy to overlook the extra cost of buying a cable.
I appreciate any help I can get!
