Because rsync backups in BackupPC is implemented in Perl, the speed of
your server is going to greatly limit your top speed no matter what
storage solution you choose.
USB 2.0 has a practical maximum throughput of 33MB/s. eSATA runs at
drive speed (I get 120MB/s out of my 1.5T drives before they fill up
50%). I converted to eSATA across the board a year ago.
