[ovirt-users] Vdo based storage domain

Hi everyone, I have read and tried to understand how vdo works, and it seems pretty impressive, but i feel like i am missing something. At the end of the day, my question is: Can I entirelly rely on the 10 times increased usable space ? As and example, I have created a 4.8tb volume based on 3x480gb samsung sm863a enterprise ssd devices. (full replica 3). Should I be confident that I can use 4.8tb for my storage domain (vms data store) without concerning about data repetabilitty in the future ? I am just trying to think as an end-user consumer that cannot predict if data that will be written to the device will be compresable or not, and only see 4.8tb as trully usable space. Any thoughts, any experience to share ? Im sorry if my question sounds noob, but i'm just trying to get under end user's hat. Thank you very much, Have a good day ! Leo
