Ultra 2 Plus USB NTFS Performance?

I found a faster way to back up my NV+ to a USB drive and that was to connect the USB drive to my PC and use copy/paste to back it up. I would start the backup and go to bed. That worked for me when I had about 60GB of data, but I then moved to eSATA connected drive, and then to backing up via rsync and now back up 1.8TB every night in just a few minutes. If you are considering a new unit, keep the Duo and use it for a back up target when backing up the new unit. No USB connection even USB3 can compete with the speed of rsync in backups between ReadyNAS units. (All ReadyNAS units support rsync, but not all competing units do).
