4K video editing NAS/DAS with data mirroring

I’m a freelance filmmaker and my current set up is currently all over the place. I work off an external SSD drive, then manually back that up to another external hard drive. I work from a Windows laptop, but still have my very old Mac Pro, which as about 4TB of old back ups. I need to get rid of this and have one main storage solution that can work with Windows and Mac.

NAS doesn’t seem necessary as I don’t need to share the footage, but I do want something that will create back-ups of my footage. Is DAS what I need? Can you create a system in which you use half the space for working from and the other half for backing that work up? I assume that is what Mirroring does. However I do need something that is fast enough, as I use 4k footage and it needs to be able to seamlessly edit like my current SSD external drive does.

I do have a thunderbolt 3 port, as well as USB 3.1 . I will eventually upgrade to a new desktop computer so I imagine that would have 10GbE port.

Thank you for taking the time to offer advice. I’m still trying to get my head around all the differences of RAID, NAS, DAS

AKiTiO Thunder3 Quad X is one solution I’ve been looking at, is this the right thing to be looking at?

AKiTiO Thunder3 Quad X is going to be a very manual way of doing things. You can use one drive for editing and then copy all that to other drives. But I would suggest NAS as this could be done automatically. You can either get 2 bay NAS which will automatically mirror the first drive to another one. Or you can get 4 bay NAS and use 1 or 2 SSD for editing and another 2 or 3 hard drives for backing up and storing old projects. You can either link aggregate two LAN ports for 2GbE speed or add a 10GbE card which is not very affordable upgrade. I would suggest getting TS-253Be or TS-453Be. If you prefer thunderbolt connectivity then TS-453BT3. But if you go for 10GbE upgrade- it can be connected to your PC without a switch to save some money.
