with dd, use "bs=<bignumber>" to increase the block size dd reads and

good value to start with would be 1048576 (1MB).
Also, you may have "stopped" the command in an unintended way - Ctl-Z
doesn't terminate a command, merely "freezes" it in its tracks
(technically, pressing Ctrl-Z causes the shell to send SIGSTOP to the
process); you could let it resume at a later time by using either "bg"
(to have it continue in the background) or "fg" (... you get the idea
;-).

Ooh, good to know, thanks Michael.
Did dd again with bs=10478576b count=50000
It completed with 250~ records in/out - and it didn't write all the
blocks it expected to (about half, I didn't save the output).
Still panics though :(
