Your 4 drive R6 would benefit noticeably from an extra disk, or if that is not possible, you may consider a R3 or R5 configuration. It will give you better performance than a R6 array with more storage capacity at the loss of a parity disk. For the rest I have no remarks, it looks good.
Thanks Harm. I do like the security afforded by R6 so will look to add more drives.
Regarding what bits of a project go where, I'm very interested in your views on combining Projects and Media Cache on a single volume versus combining Projects and Media. I see both configurations recommended but cannot seem to locate a rationale for one choice over the other.
Lee, the reasoning behind it is that you want to spread the load across as many disks as you have available, taking into consideration speed and storage capacity. A two disk R0 on the mobo often has a high burst speed, so that would be ideal for many small files like media cache. A R3/5/6 on an Areca controller will usually have the higher transfer rate but lower burst rate, so that would be ideal for large files like media. Export is not really important, because it is a one time action.
I know this is not a direct answer to your question, but there are so many factors influencing this, there is no clear cut answer. For example your editing style. Editing documentary movies (few effects/transitions, longer shots, longer timeline, few preview files) or music clips (lots of effects/transitions, short shots, short timeline, many tracks, lots of preview files, etc.) impact that decision.
""""Export is not really important, because it is a one time action.""""
i have to disagree with this Harm. for many (pro level) time is money if the export disks are not the same speed as the Capture (media) drive
then your exports(render) are going to be slower and take more time.
i think you work from 1 big drive array dont you?
which is the other option (600-800Meg/s)
Of course export time can be an important factor, but if you have just spent days or even weeks to edit and tweak the final timeline, a 60 minute or 70 minute export makes it a pretty irrelevant factor and at best secondary in comparison to editing time IMO.
Consider that in the broadcast industry there is a rough rule that says to edit 8 minutes of footage takes about one day. If you have a final movie of 60 minutes that equates roughly to 7.5 working days to edit. In that light 10 or even 20 minutes extra export time is negligent. It is even less than a single extra coffee break during those 7.5 days of intensive editing.
very valid point
considering most are not doing long play, render times are/can be critical.
frankly thats one of the biggest complaints we hear. "my renders are talking too long!"
