Right, I have done it, spent a bit more than I was going to, but it is done,
i have gone for a Terramaster F4-210
at £189, it is a four bay, so expansion for later if I need it and the difference in price between that and the 2 bay was very little
2x6TB toshiba N300
drives, they use CMR, thanks to Mick sharp for info about that, they cost £159 each
Also got an Ethernet switch as I am, putting the unit up here, even if i did put it downstairs, I want a switch up here anyway to stick the printer onto in total it is £529 as there is also some data storage insurance for £7 for three years, normally I would not bother, but for £7 it is fine.
I don't have to pay rent for 2 months as I am in advanced, so that will pay for it, but i now really have to make use of it, and my Camera, I spent all this money on updating computer, getting a decent camera and done very little with it and that is the reason why I thought a NAS would be good to store the data.
Must get some more energy in me and do this.
