Title: Scratch disk Vista 64
Post by: Huib on November 21, 2008, 12:10:56 pm

I am a very happy user now with CS4 and Vist64.
I have 16Gb onboard and when I watch the Task Manager I only use the full memory with very big files and a lot of layers.
So, the seperate scratch disk is not necessary any more!? Or do I still need it?

Other issue. When I watch the Task Manager during Photoshop I see that the used memory is getting bigger and bigger. Even when I pussed the "Purged" button.
I have to closed CS for seeing a reduce memory.

What "purge" button do you speak of?

Hello.
 I am using Vista, and this feature is not available (or I cannot find it in Task Manager). Can you be more specific?

As per your question elsewhere about my switching to an SSD based scratch disk, Photoshop can still make effective use of a scratch disk, and in fact, will create one regardless of the amount of RAM you have and whether you are running 32- or 64-bit. Photoshop needs something like 5-times the native file size for scratch disk, per image open. While it does much of it's performance in RAM, it's till saves your changes to a scratch disk until you save the final image. So, if you have even a few 50MB images open at one time, you can see how RAM/scratch disk get gobbled up quickly. Keep in mind that ever time you create a layer, use a layer adjustment, you're multiplying the size of the your image -- again, the reason Photoshop still makes use of a scratch disk.

That's good news, Huib. I can't wait to get to that point. Which motherboard/processor do you have to support the 16mb of RAM?

If you have both your internal hard drives in a RAID0 array, does the scratch disk also work in stripes?

PS's scratch "disk" works fine in stripes.
 I just picked up December's Laptop Magazine, and they go off, in some detail, about SSDs--in case you wanted to go that route. Apparently the good buy are Intels. Other SSDs will get you perhaps more space for the buck, but Intel's (at~$640) can multi-task VERY well--something most all SSDs today have problems with. The OCZ brand is particularly bad at multitasking, and can easily draw your performance down below that of a standard 7200RPM hard drive.
