  • They already did: https://www.commanderx16.com/

    you just probably want something better.

    and that is the problem building higher performance requires more advanced lithography and that is expensive and until recently was not even an option for a hobbyist (without taking a mortgage on their house).

    Given current stagnation, you need only wait about 10 years for that viable option.

  • checksums at the filesystem level does nothing to protect against memory corruption which can overwrite everything on your disk with null values and a matching checksum; fail to write anything to disk and/or do nothing.

    But that is the gamble you take every day with every GB of RAM you have.

  • Raid stopped being optimal now that btrfs and ZFS exist.

    If you plan on doing matching drives ZFS is recommended

    If you expect mismatched disks, btrfs will work.

    If you are most worried about stability get a computer with ECC memory.

    If you are most worried about performance, use SSD drives.

    If you want a bunch of storage for cheap, use spinning disks (unless you exceed the 100TB capacity range)

  • Your ZFS backup strategy should be to follow one of the following rulesets:

    3-2-1 [3 copies of the data at 2 different locations for the 1 purpose of preserving the data]

    4-3-2-1 [4 copies of the data at 3 different locations in 2 different types of media for the 1 purpose of preserving the data]

    5-4-3-2-1 [5 copies of the data at 4 different locations across 3 different continents in 2 different types of media for the 1 purpose of preserving the data]

    The details of the backup is more if you have a second system to enable ZFS send/receive or if you have to transport deltas from ZFS send

  • Yes in a scenario, which you are in a cold climate which it is always cold outside. Then yes, thermal energy storage would be an extremely efficient option.

    It doesn't apply to most living humans but I grant you that special case.

    yes, I did look at your link and noted all of sites are those near mountain ranges; which I certainly grant you is near (within 100 miles of) most human population centers.
