VM Disk speed test faster than host

Hi all,
I'm running a Windows 11 VM on my M1 Pro MBP 14" which is installed on an external SSD (Just a M.2 SSD in a 10 GBPS USB-C enclosure).
If I run a speed test via the BlackMagic tool I get about 980 MB's Read and Write respectively which is about the max supported by the enclosure. However, If I run a speed test from within the VM with CrystalDiskMark I get much higher speeds. Please see screens below.




One the other hand, I've got a Mac Mini M2 Pro, exactly the same setup; Win 11 VM on external SSD; just with a thunderbolt enclosure, which produces normal results, please see below.





Anyone can explain what's happening? How can the MBP VM disk be faster than the actual drive it's been installed on?

 

My instinct is that you're Actually testing the speed of the system memory, but beyond that, IDK.

 

Thanks for the reply, I was thinking the same, but why not on the Mac Mini? Both devices got 32GB of RAM.

 

Slightly different tech I guess. Apple is weird with how they choose to design things.
