Fourth: exfat (needed or big files) does not have a journal like ext3 or ext4, so data may be going corrupt on the harddrive and could not be restored.
That's not what a journal is for, and if the copy completes and the disk is unmounted the data is fine. The journal is there for cases when the filesystem isn't shut down properly, as in a loss of power or a system crash. Some implementations will journal data, but most only journal metadata. A metadata journal's main purpose is to avoid having to run fsck; the filesystem will end up in essentially the same state whether using a journal or using fsck, but the journal is much, much faster.
Sixth: USB3 is (IMO) very slow against gigabit.
This is incorrect: USB 3.0 is 5Gb/s, and various implmentations of USB 3.1 or 3.2 can run at 10Gb/s or 20Gb/s. Copying a large amount of data via an external drive can be many times faster than copying via the network, depending on the speed of the drive and the speed of the network.
