			$this->bbcode_second_pass_quote('WarheadsSE', 'P')PV4 with linux-kirkwood, to a USB3 WD 3TB MyBook (probably not high speed disk), I get a sustained ~ 22MB/s write over samba, which we know is a bit of a CPU hog.
I just ran a write/read speed test on my PPv4.  Using a Hitachi Coolspin 4TB 7200rpm hard drive installed in a Datatale RS-M2QJ 2-Bay raid box configured for JBOD:
$this->bbcode_list('2')
 Plugged into USB 2.0 top port, achieved ~28.2MB/s read and ~30.1MB/s write over samba, HD drive formatted HFS+. Plugged into USB 3.0 back port, achieved ~37.2MB/s read and ~40.4MB/s write over samba, HD formatted HFs+.I was using the 'hdparm -t' to measure the read speed and the 'dd' command to measure the write speed.  Curious though, I would have thought the read speed would have been better then the write speed.
