Picked one of these up a few days ago from amazon, great fast shipping, high quality unit, loaded it up with 8 drives and it was online within 15 minutes.
It's still checking parity, but that hasn't stopped me writing to it @ 80-100MB/sec for the past 24 hours.
I wish that the underlying OS had better package management system, I use Duplicity for alot of backups, and its not available from what I can tell.
Now to see if my old drobo will work as a USB device on the Synology so I can use it for backups.
Also would be nice if they used ZFS or some sort of filesystem that allowed for easy versioning.
