Blu-Ray data Storage Questions

[kt515]

I am working on a way to switch my company's long term storage from paper to blu-ray. I have several questions and concerns and I am not an expert at blu-ray. Please any personal experience, knowledge or any insight will be greatly appreciated.

1.) What are the benefits to having the blu-ray drive internal as opposed to external? Does external BD burners function at a level not as high as internal drives?

2.) Will a high powered CAD station be meet the requirements for a Blu ray burner to be used on the computer?

3.) If only new data is being added to a BD-RE disc (no information is being recorded over) will the disc wear out and affect the data?

4.) Is there a way to lock the data on a BD-RE disc after the final burning has been made so no data can be altered or deleted (so data can only be read) ?

5.) Is there a way to have a time key that cannot be altered for data that is burned onto the disc (authentication) ?

6.) Once I have filled a 25 GB disc and I want to make a duplicate of it- What is the best way to do this with only having one blu-ray burner? (for data storage reasons there needs to be two copies- one on site one off site)


Thank you so much for your responses
