Does anyone have the Lacie 5Big Network 2 in use? I'm planning on purchasing/building a NAS as a backup within my home network and remote access outside for my media center which is windows based. I won't be using any RAID configurations, as i will be doing the backups manually. If i did the Lacie, I was planning on installing a 500GB and 3TB first off with the diskless version, but Lacie said that the same size drives need to be installed in each slot. Is this true? Has anyone had any experience with this drive and the features it offers? Thanks
