I was leaning towards no 1 myself. I do editing about 10% of the time so that would make sense. The only downside is that I will have to keep that system drive lean and clean since space is so limited on SSDs. The one I'm getting will be about 120GB decisions, decisions. Thanks for the insight Chris.

The thread others in Adobe pointed me to on this issue is here:


The advice there is Premiere-centric, but in short, for 3 drives, one for OS and programs, one for media and projects, and the SSD for previews, cache, and exports.

Four drives is preferred, with 2 of them in a RAID 0. Then the advice is a solo drive for OS and programs, the SSD for cache, and the RAID for media, projects, previews, and exports.

Regardless, SSD for caches. 

If you were going 3 drives, and almost exclusively AE, your first choice for configuration was good, as AE is more serial in nature than Premiere.

Primarily After Effects although I have been working more Premiere Pro into my workflow as of late. I will be adding a GTX580 to the system which helps both applications.

When you say "for CS6", are you talking just After Effects, or multiple programs in the suite?

So what would be the ideal arrangement for CS6 then if there were 2 7200rpm drives and one 120GB SSD?

SSD System disc/Cache
2x 7200 HDD Raid 0 for Media?

or

7200 HDD for System
SSD all by itself for cache
7200 HDD for media?

Or would it be worth it to buy a fourth drive (either SSD or 7200rpm drive) The former for System and the latter for striping with the other 7200rpm drive for media?

Agreed.  You might be able to scrub around a little more smoothly, but I'd skip it unless you're doing stereo 4K work or something similarly bandwidth intensive.

A single 6g SSD is orders of magnitude faster than a comparable 7200rpm drive. I'd skip RAID, but I tend to avoid complexity when I can.

> I'm starting to spec out a new machine and an SSD for the cache is definitely in order. It'll be 6G SATA-connected at minimum, but I'm actually considering perhaps RAID-0 stripe of two 6G SSD's to improve performance and reduce latency all-the-more. Anyone have any thoughts on how much of a difference that would make in AE? Worth doing? Assume fully modern mobo/chipset machine.

One thing that would make it even better is the ability to clear the cache based on a particular project. I'm always juggling several projects at once and when I finish one I would like to clear the cache of that project.
