Hi I am about to upgrade to something newer than my current workstation in the= next 3 months time, and was considering a raid 0 SSD for a system+programs= drive, a 4-6 raid 0 harddisk raid for scratch/proxy drive. But with the new cache system, is it then better to get 1 SSD drive for cac= he just for the better seek times on an SSD vs regular harddrive raid? What about the FusionIO ioFX "drives" that Steve Forde seemed to endorse at= NAB, is the seek times on that so much better that it is worth the price p= rimium. and how does that stack up to the intel SSD 910? (http://www.anandt= ech.com/show/5743/intels-ssd-910-400800gb-mlchet-pcie-shipping-in-1h-2012) my projects and mediafiles are on a server and/or local attached SAS raid-6= drives, depending on project size/speed reqirements. Robert Kjettrup / Grafiker / STV Mayday Mobil: 25 18 95 16 Mail: robert@stvmayday.dk 2012/5/18 Nathan Shipley > Quick version: +1 to the setup Chris describes. I use it and it's fast. = Get an extra small SSD if you can for scratch space. 64 GB ones are about = $80. Details version: My latest Mac Pro rig is basically set up like Chris desc= ribes: has a a 256GB SSD for system boot, a 64 GB SSD for scratch/temp/pre= views space, and a 1 TB drive for active projects. As Chris mentions, it w= ould be nice to drop another 1 TB drive and set up a RAID array on my proje= cts drive, but, overall, the system is really fast and I'm happy with the p= erformance. System startup and application startup times are an after-thou= ght. 32 GB of RAM keeps AE fast for multi-processor renders and a 9 TB RAI= D NAS does Time Machine backups and archives projects. I'm mainly using AE, Nuke, Maya, and a little bit of Premiere. If I only had one SSD, I'd make it the system drive and scratch space. Jus= t such a difference in interactivity starting programs. I'd use the same setup if I was using a PC. It's a good configuration and = worth the cost of more expensive SSDs. Both on the workstation and my lapt= op, installing SSDs has been the most impactful upgrade I've done in the la= st few years. - N On Fri, May 18, 2012 at 10:41 AM, Robert Houghton > wrote: I was leaning towards no 1 myself.

Regardless, SSD for caches. If you were going 3 drives, and almost exclusively AE, your first choice fo= r configuration was good, as AE is more serial in nature than Premiere. - Chris On May 17, 2012, at 10:32 PM, Robert Houghton wrote: Primarily After Effects although I have been working more Premiere Pro into= my workflow as of late.
