Right now I'm done with almost 20GB download from the BSD machine to my lap=
top by ftp, and 5GB to the BSD from http, in the mean while I've done almos=
t 40GB of torrentflux's checking existing data and I do a make install to a=
 port, all in the same time and everything is working great. I hope it will=
 continue to work just like this.=0A=0AThe hdd temperatures are:=0A# smartc=
