Not a good guess. To use DD you need a computer with dd and a fast
cpu. I did top while dd was working and it was taking 70% of the
cpu's time :-P
It's one of the oldest Unix programs: it will copy as fast as your
system can go. Yes, a fast system will copy faster.
(BTW, it is a good guess. You are copying straight off the device,
bypassing the filesystem.
Please explain. I am taking bytes off and putting them on file
systems. Both Hard Drives need to be running.
The primary problem I think is the
possibility of missing cached writes. Things like log files will
also be in an odd state, but that is unlikely to ever be critical.
However backups, and what you are doing is essentially the same
thing, are best done on unmounted systems.)
I can say that my success was with me sending and receiving emails
and additions to the web browser while dd on this computer was doing
it's thing. No problems.
