    150GB Photoshop file and SSD scratch disk option


      Hi all,


      First post here so be gentle.


      I know this question has been asked a lot but I'm looking for some guidance based on my situation.


      I'm working with a PSB file that's 150GB (uncompressed and roughly 208,000 X 208,000 px). This files contains 169 aerial image tiles that are 16,000 X 16,000 px.

      I'm in the process of editing the sea so I have a layer with a mask that I'm manually painting in.

      This file is located on a server with 10 Gbps Ethernet connection so this not a bottleneck.


      Currently the scratch disk is about 800GB.


      I'm looking at ways to reducing the loading times of this file.

      My PC spec is below, but in a nutshell SSD has OS and Program files and HDD is used solely for scratch disk


      I'm looking at getting a 2TB SSD (Samsung 860 Pro) but before I do will this reduce the loading times??


      PC Spec:

      Photoshop CS6


      Win 10 Pro 64bit

      RAM 32GB

      GTX 1070 (6GB GRAM)

      Intel i7-2600 3.4GHz

      256GB SSD (sata 3) (with OS and Program Files) Micron C400-MTFDDAK256MAM

      HDD 2TB (1.6TB free) (sata 3) WD RE4 WD2003FYYS 2TB 7200 RPM 64MB Cache

      Any help would be much appreciated.

          This is a huge file and open/save will take a long time, perhaps minutes, even from a local disk. I think you should just get used to that.


          That said, an SSD as scratch disk would speed things up. But you will probably need at least 1TB just as scratch space for this single file.


          Personally, the mere idea of working over a network makes me shudder, no matter the nominal speed. Actual speeds are usually nowhere near. At least work locally, then save to server.
