Hello all,

I've recently replaced the optical bay of my macBook Pro with a second SSD, meaning that I have a pair of 120GB SSDs inside the machine (which are not identical).

My question is how best to use that space?

Drive 1 is the stock Apple one.
Drive 2 is the faster OWC one.

At the moment it's like this:

Drive 2 has OSX and applications (with 60GB to spare).
Drive 1 has two partitions:
a) 60GB Scratch Disk
b) 60GB Windows 7 in BootCamp

Because Drive 2, the OWC brand SSD is a much faster disk, should I move the scratch and render cache over to it instead of the slower drive?

I'm about to undertake a project in Premiere with over 4TB of video out of the 7D so I'm thinking I'm going to need an external scratch disk anyway. Am I right?

Thanks for your help,
-- John

John,

I doubt you will notice much of a difference between the two; but if you want to split hairs, choose the one with the best sequential read/writes for your media, and the one with the best random access transfer rates for your OS.

The more important consideration is that you seem to be serious about editing 4 TB of source material on a laptop with no mention of external data storage for source files, backups, rendered content, etc. All notebooks are a compromise between power and portability, and your is heavily weighted towards portability. All this is to say yes--you will need external storage, and a lot of it, and in multiple locations. And even once you have all that, you will still be struggling against the inherent limitations of your laptop.

In summary, I wouldn't recommend it...
