10.3.23_PhotoShop not utilizing NVMe SSD correctly

[Gene27167201cqus]

Hey guys I got this new nvme corsair mp600 1tb gen 4 pcie

to use for faster saving and loading of PSB files .

but it doesn’t activate at all in task manager when opening PSB file or saving file and so the times haven’t changed at all....

I have it set as my only scratch disk as well and the PSB files are literally inside the drive itself, and I’m opening from there as well

CrystalDiskMark tested my nvme to show that its read speed is properly 5gb/s and write speed is 4gb/s exactly wha tis should be

Anyone know what’s going on?

What are your settings for Preferences > File Handling > Disable Compression of PSD and PSB files?

For fastest saving and opening, that should be checked i.e. compression disabled. The files will be smaller if it is unchecked, but much slower to open and close as the the bottleneck will be the file compression not the disk. The time difference can be very large and surprising.

Thanks alot man really really helped, Ill ask you the same question here too if you dont mind.

I noticed that i was able to drop the save time from 20m to 1m after taking away compression. Files seize went from 3.47gb to 38gb.
Fosse mentioned that "encoding, packaging/unpackaging for storage, and that is done by the CPU. Actually writing to disk is a very small part of it."

That being the case, I just upgraded CPU from 1700x to 3700x, clock speeds are much faster and yet I didnt notice any change in the packing or unpacking of the file/ save load times.

Only compression being turned off made a difference.

In performance under task manager, during save load, it only uses 20-30% cpu as well...

That being the case how can i utilize more CPU (nvme, or whatever solution) to further decrease the save load times from 1m to a few seconds?

The scratch disk has no impact on save and open times. That's encoding, packaging/unpackaging for storage, and that is done by the CPU. Actually writing to disk is a very small part of it.

If you have long save/open times, you probably have compression enabled. Compression is very CPU-intensive and consumes a lot of CPU time. Disabling compression will reduce save/open times dramatically, sometimes by a factor of 4 or 5.

You will mainly see a benefit of a fast scratch drive while working on very big files (around a GB and up), or you have many files open simultaneously. In these situations, Photoshop's memory requirements vastly exceed any RAM you may have installed.

If you open the NVMe in Explorer while Photoshop is running with files open, you will see a number of files called "PhotoshopTemp<random numbers>. That's the scratch files, and they will be in 16GB chunks.

 it doesn’t activate at all in task manager

Hi Gene.  Can you clarify the above? Do you mean in the Task manager > Performance tab?  (I am using Windows 11, so your's might be different.  

 

The PSB format id ascociated with large file sizes.  Do you know what the size of the problem file(s) is?

It sounds like you have been able to select the new drive as Scratch space.  Is that right?

Open File Explorer and look at that drive's root directory, and see what size the Photoshop Temp file(s) is/are.  With the PSB file loaded in Photoshop. Look for activity on Performance Monitor and see if you can see any bottlenecks.

Hey, yes I was able to see that the nvm has 24gb of temp file when running PS, but it doesnt show the NVme actively being used in perfomrance task mangaer like the ram shows a 100% kind of thing.

[Trevor.Dennis]

How much RAM do you have?

How much is alocated to Photoshop?
