VeraCrypt has been tried and tested but it appears to perform poorly on modern NVME devices due to inherent limitations in its TrueCrypt based architecture. As a Windows FOSS alternative, you can consider DiskCryptor. However, unlike VeraCrypt, it has not been audited (to my knowledge) and lacks many QoL features. Use at your own discretion.

So the same shit. The only difference is that besides Microsoft, you also have the key.
