1. Re: Can PS app AND its scratch disk be put on the same SSD?
Noel Carboni Aug 2, 2012 10:44 AM (in response to *Rich*)Actually, that can work very well indeed.
The high throughput of SSD coupled with the zero seek times makes SSD a good choice to host everything.
I have a RAID array of four SSDs that I use for everything that's running - Windows, the swap file, all apps, and Photoshop scratch. I also have some spinning drives on the system, but they're just for archival and are spun down (power saving state) most of the time.
I can barely notice when Photoshop goes to its scratch files.

*Rich* Aug 2, 2012 10:49 AM (in response to Noel Carboni)Thanks Noel. For a single dedicated SSD containing both PS and its scratch disk, would you assign each its own volume?

Noel Carboni Aug 2, 2012 10:49 AM (in response to Noel Carboni)One thing to keep in mind... You'll want to over provision your system with SSD storage, as Photoshop can chew up a couple hundred gigabytes of free space pretty easily. Yes, I know that's expensive, but it's the price one has to pay for the highest possible performance.
Overprovisioning is also a good idea from the perspective of allowing a modern SSD to do its internal maintenance efficiently as well.

Noel Carboni Aug 2, 2012 10:51 AM (in response to *Rich*)No, there's no advantage to partitioning the disk. It will just fragment your free space.
Plus I think Photoshop likes using drive C: best for scratch, from the perspective of seeing the least number of unexpected things go wrong.

*Rich* Aug 2, 2012 10:55 AM (in response to Noel Carboni)Thanks. So, let's say for photo editing 40 - 60 MB files with up to 20 layers, would a 240GB SSD be adequate, or could I squeek by with a 120GB?

Noel Carboni Aug 2, 2012 11:20 AM (in response to *Rich*)Well, I built a 2 TB array and have 700 GB filled at this point so I'd have to say go for the more expensive drive, as it will put off the time that you'll have to start worrying about running out of space. Then in the future you can add a second (third, etc.) drive of the same size building a RAID array, to increase your space.
