How to encrypt HDD with cache?

I have a HDD (2TB and 128MB cache). If I'm not wrong an HDD is better for veracrypt that is why I decided to buy the HDD. SSDs seem to have issues with veracrypt (TRIM, Wear Leveling).
I want to install Windows 10 on the 2 TB HDD. But I'm unsure how to encrypt the drive after I installed Windows. In the past I already encrypted an SSD (System Partition) with Veracrypt, and I could only encrypt the system partition and not the whole drive. Is this still the case if I use the HDD as the System Partition, and is it any less safe then the encryption of the whole drive? Also the HDD seems to have a thing called cache. I haven't used HDDs in ages. Is this anything I need to consider with Veracrypt? Can Veracrypt securly encrypt a HDD running Windows 10 that has a cache?
I also have an old external HDD that I would like to encrypt. Is there anything to consider there?
Does anyone know the answer?
Your questions regarding system encryption should be covered by VC's documentation:
https://veracrypt.fr/en/System%20Encryption.html
The cache of your HDD should not compromise security. Data read from and written to a VC volume is only decrypted on-the-fly in RAM. That's why your HDD would never see unencrypted data from within a VC volume.
