So I've found myself in a bit of a mess regarding file organization and hard drives. I have 5 hard drives attached to my 2011 iMac (USB 2.0 + Thunderbolt) at this point. I've purchased them over the years when I've needed more space for photos and such and have ended up here. All of the hard drives have different capacities: 2 2tb, 1 3tb, 1 4tb and my internal. Everything is backed up using Crashplan. Here's how it's setup currently: Internal: "Working" files (roughly half the year) 4tb Seagate Backup Plus USB 2.0: All photos (going back to 2007) 3tb Seagate Backup Plus USB 2.0: Partial backup of 4tb 2tb Seagate Backup Plus USB 2.0: Partial backup of 4tb 2tb Western Digital something or over USB 2.0: Music and videos I currently have roughly 3.4tb of photo files at the moment and thats going up. Its a mess. I can never keep track of where everything is. The 4tb will be full by the middle of next year (or sooner) so I'm going to have to figure something out then as well. Here's what I'm looking for: I want ALL of my photos somehow accessible via Lightroom. I want my current "working" photos on my internal hard drive for speed purposes. I want everything backed up twice (one of which is my crashplan setup). What should I do here? I don't want to invest a ton of money here, but am open to options.
