I have downloaded Core Version 23.
The Blockchain size is 500G as expected,
Still - the total amount of storage on the disk is more than 800G (which includes only this software).

I should note that I use VM on a specific 1TB SSD to run the Node.
I used Ubuntu since I have found a very good Tutorial on Youtube (although I do not have any experience with Linux...).

Looking forward to your insights,
Nir
