not tested purely linear writes, but writing large files result in 
slowdowns too. maybe smaller.

Ask someone to test speed with

dd if=/dev/zero of=/dev/seagate-archive bs=1m


and check speed AFTER 20-30GB got written.

in theory it should be fast.

in theory there is no difference between theory and practice. In practice 
it is ;)

Actually it should be OK if firmware is well written. In my opinion it is 
usable but not really well written.
