Hello. I just upgraded to Ibex 64 bit and still have this problem.
Transfer speeds are typically 7-8 MB/s between drives. Really annoying.
Both drives are ext3, mounted with noatime,nodiratime. I did NOT have
this problem with Ibex 32 bit. Write caches are both enabled, and the
problem is only when moving files sda => sdb, not the other way around.
