Task Time is Disk or CPU limitedīoth disk and CPU speed influence the total time for an operation to run. See the test results with the Intel X25-M SSD. Unless you’re considering a server-grade SSD, a striped RAID offers far higher transfer rates at far lower cost and far higher capacity. Please see What about a solid state drive? for an overview of solid state disks (SSDs).

* “scratch” is what you need when contemplating the CS4 upgrade price! What about a solid state disk (SSD)? See Using a RAM disk for Photoshop scratch*.

Some users will never experience the need for a scratch disk don’t bother with this stuff unless Photoshop starts using it (noisy disk as the drive seeks, very slow operation, low “efficiency” in the Photoshop status readout).ĭo it yourself install video. Please see the RAID page for details on creating a striped RAID. Figure a least 3X the memory for a file eg 1.5GB memory for a 500MB file.Ī fast Photoshop scratch disk is fast mainly because of transfer rate, which means creating a striped RAID for optimal results. But when you open several files of that size, use a long history or cache levels, add many layers, etc, then the scratch disk will start to be used significantly.

See the Configuration page for details.įor users with moderate size files (a single file of up to 500MB or so), the scratch volume is used sparingly, provided that the system as as a whole has adequate RAM (eg 8GB on a Mac Pro). When the scratch disk gets used, testing shows that it’s essential to use the BiggerTiles plugin in conjunction with DisableScratchCompress plugin. Then Photoshop must “swap” data to and from the hard disk, a far slower proposition than manipulating it in main memory. The Photoshop “scratch” volume comes into play when Photoshop utilizes as much memory as it can, but still cannot hold all its working data in memory. √ No more slow and noisy hard drives! When Photoshop uses a scratch disk The remainder of this discussion is what happens when Photoshop does not have enough memory eg when working with very large files (many megapixel and/or many layers). In this situation, ample memory and fast hard disks exert far more influence on overall processing time. When the scratch disk gets involved, CPU speed has little or no influence on performance, because the CPU will be waiting for data much of the time.

See Multi-core Computers and Apple Mac Pro and All About Mac Pro Memory to understand these issues better.ĭon’t have time to read all the details? Cut straight to the conclusions, but do not miss the important Photoshop configuration information. When the file(s) fit into memory, performance is governed exclusively by CPU clock speed along with on-chip cache and number of cores, and main memory bandwidth (and also your operating system and/or other programs running at the same time). This study is not about how fast Photoshop can execute Unsharp Mask or Gaussian Blur or various filters those operations are functions of the CPU speed and memory bandwidth it’s a simple choice: buy the fastest (GHz) CPU with a premium video card, should you determine that CPU speed is your primary impediment. The performance gains for working with large files are as much as 5X, making the choice of system configuration critical to productive work with Photoshop. These questions are answered definitively for the Mac Pro and MacBook Pro. How do I configure Photoshop for best performance?.
