    I’m sorry but I’m too lazy to dig up links to back up my claim. But you are correct in that electric vehicles pollute far more being produced than combustion engine cars, however the electric vehicles gain that back over it’s lifetime if your charge from mostly non-fossil sources. The figures I have read says that over the lifetime of a car, electrics output 70% less CO2 than combustion cars, and that includes the production of each of the cars.




  • ZFS doesn’t really support mismatched disks. In OP’s case it would behave as if it was 4x 2TB disks, making 4 TB of raw storage unusable, with 1 disk of parity that would yield 6TB of usable storage. In the future the 2x 2TB disks could be swapped with 4 TB disks, and then ZFS would make use of all the storage, yielding 12 TB of usable storage.

    BTRFS handles mismatched disks just fine, however it’s RAID5 and RAID6 modes are still partially broken. RAID1 works fine, but results in half the storage being used for parity, so this would again yield a total of 6TB usable with the current disks.












    • 1TB NVMe SSD
      • 512 MB EFI
      • BTRFS partition for / filling up the rest
    • Ancient 128 GB SATA SSD
      • Swap
    • 1TB SATA SSD
      • 500 GB Windows installation for VR games
      • 500 GB BTRFS partition mounted at /mnt/games

    Since both my root and home are on the same BTRFS partition they share space.

    I have made sure to create sub volumes for the Steam and Game install directories, to avoid taking snapshots of them.

    Steam has 2 “libraries” registered, one in my home directory and one in /mnt/games
