I'm upgrading from Windows to my first Mac in a couple months, and I figured in the meantime I might as well upgrade my storage solution. I need some real advice though because I'm new to the idea of an NAS solution and I could use some real help. I currently use two 2TB external hard drives to back up my data. Every month or so, I make identical changes on both of them so that they mirror each other. I understand this is a time-consuming way of doing things, but I'm paranoid about my data and I never knew about RAID so this is how I'm doing it. I've recently learned about RAID, and RAID1 specifically. For my usage, it makes a lot of sense for me to have a setup with two hard drives (at least 4TB each) running a RAID1 configuration. So basically, I'm looking for advice on what the best device to use is. Obviously, it needs to be compatible with Mac. It doesn't need any fancy backup software, I prefer to manage what gets backed up on my own. I want something where I can drag and drop onto the hard drive from my Macbook. The only requirement software wise is that I need to be able to password protect the entire drive, or at least parts of it. The other thing that does confuse me is this concept of NAS. I understand that this means I can read/write to the hard drive over the internet, but is this a time efficient process? I have approximately 20 Mbps internet connection in my house, and I feel like I wouldn't be able to transfer data wirelessly as quickly as I would with a wire. I wouldn't be transferring data often (every month or so), so I would be perfectly fine with a device that allowed me to plug my laptop into it when I wanted to do major data transfers. I'm guessing USB3? Finally, do these devices constantly run? I'd like one that I'd be able to turn off because I may go weeks at a time without using it. Would appreciate any advice anyone could give on what I should buy. I've seen brands like Synology and WD, but it's very overwhelming for a newbie. Thanks!
