Slow USB is Slow!

Just in case anyone is wondering just how long it will take an Atom based netbook to zero out a full 1.5TB HD using a USB 2.0 caddy:

root@neutron : time dd if=/dev/zero of=/dev/sdb
dd: writing to ‘/dev/sdb’: No space left on device
2930277169+0 records in
2930277168+0 records out
1500301910016 bytes (1.5 TB) copied, 282464 s, 5.3 MB/s

real    4707m44.060s
user    177m33.919s
sys     612m29.236s
