Hey everyone. I think this is my first post here. I've been using AE fulltime for motion graphics and recently have bought a new Macbook pro 15" retina.
The MBP has a REALLY fast SSD (read write 1000+ MBPS on black magic tests) however it is only 250gb and gets filled up with media cache from AE quite fast ( can only allocate about 70gb to it).
I'm also using a USB3.0 HDD for most of my stock footage/sound library as well as archived projects. What I do right now is create the project on my mac's desktop, then move it to the HDD later once it's finished.
Now here's my question. I've been needing more portability lately and the 3TB HDD is too big and heavy to haul around, especially with it's own power supply.
I'm now thinking to purchase an external SSD over USB3.0. The one I'm looking at is a MyDigitalSSD OTG 250gb and is advertised to have speeds up to 480MBPS on read and write.
Do you guys think this would be fast enough for mediacache usage? Or should I keep my projects on it along with the stock footage library that I need, and use the 70gb media cache on my Mac SSD?
I'd really like to elminiate the big HDD out of my everyday workflow. Trying to figure out which way would yield the fast workflow too so all the help is welcome!
PS. one more question about the Media Cache, what happens if it fills up? Does it get overwritten or does it start slowing things down? Can't seem to find an answer to that.
Appreciate your response.
Is there a way to disable Media Cache all together? I wasn't aware of that, so I'd appreciate if you could give me a link on this topic.
If it turns out to be unnecessary for my work (as I mostly work with motion graphics and rarely use footage, although this isn't always 100% true). I guess I could even go with lower media cache limit, and use the SSD to hold all my project files and stock library that I use on daily basis.

Let's back up. There are two separate caches: the After Effects disk cache (which stores rendered frames of rendered layers and composites), and the Adobe Conformed Media Cache (which stores processed caches for some multimedia formats to improve performance).
My comments above were related to the disk cache, which automatically fills as you work, because it is constantly saving partial renders of your work to disk. This is the cache for which you can set a size limit.
If you're talking about the media cache, which is used only for comforming assets you import, then what I said above does not apply. You cannot set a size limit, and the Adobe apps which share this cache do not automatically prune it. You would have to manually clear this from time to time to reclaim disk space.
