Basically we have hq scans of thousands of old family photos. Plus tons of family video. We want to host them where we can still have total control over the content and restrict access. I'm a php programmer, so the security is not an issue. What is an issue is finding a host to store 10 TB of data and not be paying a ton of money.
We really are not planning on a lot of traffic. Maybe 1-10 visitors a day; family only. Kind of like an online library.
