Selecting Scratch Disks

The Performance preferences are available to help you get the best performance out of your computer, by letting you choose one or more hard drive for scratch operations. When your computer doesn’t have enough RAM to perform an operation, Photoshop uses free space on any available drive, known as a Scratch Disk. Photoshop runs faster when you divide the Scratch Disk workload. Scratch operations are performed on your hard drive, and take place when Photoshop is using one of its many filters and adjustments. Photoshop detects and displays all available internal disks in the Performance preferences dialog box, where you can select the disks you want. By assigning additional hard drives to the task, you speed up Photoshop’s overall performance. Scratch Disk changes take effect the next time you start Photoshop.
