I think there is something very wrong with disk performance after encryption.

I start with the performance without encryption: (CRUCIAL P310 1TB NVME GPT )

Then the performance after the drive encryption using Veracrypt 1.26.20
I have a recent Ryzen 9700X . Veracrypt Benchmark:

Encrypted Drive Performance using AES SHA512:

These were the previous system drives encrypted with Veracrypt AND a very old Intel i7 6700k (2014) (SSDs, which should be much slower and are very close to nvme instead !!! ):

Current encrypted NON-System Drive (SSD) is somehow faster than System drive (NVME):

So my question is: How is it possible that SSD drives and a 10 year old processor are very close in performance with a NVME drive with a recent AMD processor whose performance is significantly superior to my previous one ? Did i waste my money buying a new processor and a nvme drive ? The main problem is the HUGE performance drop after the system drive encryption, and why the non-system drive, which is a SSD, is so much faster ?

according to veracrypt benchmark, i should be well within my nvme capabilities, since i used AES. Instead, it's a disaster !
