First I want to start off by saying, that I am in the planning stages of this. I have bought no hardware, and everything is a possibility to ensure the success of this project while keeping convenience and portability in mind.
I am looking for a solution that will allow me to have 2 RAID arrays comprised of 2x 3Tb drives each. These will be my LTRS drives. Referred to as LTRS0, first array, and LTRS1, second array. These drives are meant to store my work, music, videos, and documents from system build to system build. I want to ensure their long term integrity by placing them within RAID 1. Basically, LTRS0 will have 2 HDD of 3Tb in RAID 1, LTRS1 will have 2 HDDs of 3TB in RAID 1, but they can contain different data.
I want to know what my best option is based on these requirements. Should I get a PCI(e) card that I can take from system to system as I build them, or should I get a NAS and put all of my data in that, or should I use the on board motherboard controller and just make sure I have the same controller from system build to system build?
- The issues that come with each are somewhat daunting as well, as for example the first option PCI(e) might get in the way of a Cross Fire or SLI setup.
The second option NAS might be slower then internal storage as it's going across a 1Gbps link and not say a 3Gbps SATA, or 6Gbps SATA interconnect.
The other option would be a light path / thunderbolt NAS but those tend to run expensive and I don't own a Mac, and I can't seem to find a Thunberbolt PCI(e) card on line, and that might have the same issues as the first option (getting in the way of an SLI / CX setup.
- The third option might not work as well because manufactures might change RAID controllers from motherboard to motherboard and that would reduce the LTRS lifetime.
So, I turn to you, of the options given, what's the best one to meet the goal of long term redundant storage. If you could provide product details that would be great, or information on your own in house solution.
