Photoshop Saving File Qustion

Hi guys & gals, I hope I put this in the right forum. I just purchased a new Mac with a SSD and could not be happier but I have a question. I am not concerned about longevity and limited number of writes a SSD can accomplish in it's life span but the issue did raise a question in my mind, what counts as a "write" in a program like Lightroom/Photoshop? I am saving fils to an external drive so that is not counted but what about saves inside a program like PS/LR? Does a save in the program equal a write to the boot drive in a temp file? Is that considered the same as saving a file to the SSD? Thanks in advance for any replies I may reeive.

You'd have to have a very good understanding of how SSD controllers and the cache/history process works to even attempt to figure out what kind of wear is happening. The simple answer is that programs that use cache/history's will tax SSD's more than the average program. The actual writing of the image files probably doesn't even come close to how much a program is swapping, but I seriously doubt you'll have to worry about it. I'm still using a three year old SSD that is used daily, rarely turns off, and constantly does heavy work loads (gaming, photography, videography, web design, etc).

In practice I doubt you'll have an issues. It should last as long as that computer, probably even longer.

Why are you using external disks? You lose much of your speed advantage there. Though if it's a thunderbolt disk and the cache is on SSD you're fine.
