Thank you all for your comments.
In an year from now, we will upgrade to HD so that again will change things.
The size of the HDs on the server can be anywhere from 4 to 10 TB.
So the box with the hardrives will connect to a mac which will be the server and from there we should be able to connect through fiber optic at least 3 but maybe 6 macs. We are using final cut pro 7, which is not really much into sharing, but we will work on different files which will be in the same place, on the server.
Is there something wrong with this picture?
Where can I see how much speed requires each stream for DV and HD or Prores?
If any of you has any suggestions on which rack for harddrives is the best in this situation, please give me a link 🙂
Thanks again!
