Hi guys, I am coming to the point where I am filling my 500GB that is on my hard drive. Most of this is due to the fact that I take a lot of photo's both for pleasure and for money so it has come to the point where I will need to offload some. At the moment I have one copy of my lightroom catalogue on my computer and another clone on a 1tb portable drive that I carry around with me. Is the best suggestion to buy a Raid 1 array (looking at this WD 2x2tb) and then offloading the archived photo's, say everything shot at least a year ago and therefore not needed now to this drive. This will mean that I will have a Raid 1 copy of the archive photos and still have a backup of my current photos through the portable drive. The Raid 1 backup will also stay at my parents house which I visit a few times a month. Just to point out once the older photo's are offloaded onto the Raid 1 drive I will delete them from my computer and therefore they will be removed from my portable back up drive as it just copies exactly what is in my lightroom folder. Does this sound alright?
