Why is my SSD transferring data (it seems) slowly?

[FailPr00f]

I decided to transfer a game (Lost Ark) from my WD_BLACK SN750 1 TB M.2-2280 NVME Solid State Drive to my Toshiba 3 TB 3.5" 7200RPM Internal Hard Drive.

 

My question is why does it seem to transfer so slowly from my SSD to my HDD? Both are in good health (checked smart data through crystaldiskinfo). On the SSD, the max sequential read speed is supposed to be up to 3430MB/s and the max sequential write speed is supposed to be up to 3000MB/s, but both seem much, much slower. I think maybe I'm misreading or misinterpreting the data here or maybe not. Is the SSD being bottlenecked by the HDD? Either way can someone help me out and explain this to me?

I've attached 4 images below. The first two show transferring Lost Ark from SSD to HDD with SSD and HDD view from task manager performance tab, and the second two show transferring Lost Ark from HDD to SSD with SSD and HDD view from task manager performance tab.

 

Also here are my full PC specs: https://pcpartpicker.com/list/tB3GrV. If any more info is needed just let me know.

 

Thanks,

Quentin

Because mechanical drives are limited to 150MB/s~ in most cases. No matter how fast your SSD is, your HDD is constrained to its slow speeds.

File transfers between 2 storage mediums only operate as fast as the slowest medium. Since you're moving files between a spinning rust disk (HDD) and a lightning flashy boi (SSD), your speeds are limited to the read & write capabilities of the slower drive.

You can clearly see in your own screenshots that your HDD is being maxed out when you copy from and to. That is literally the definition of bottleneck.

Okay yeah makes sense. As I was finishing writing up the post I kind of figured it was bottleneck looking at the graph so that's why I threw that question in there lol. Still getting used to posting on here so good practice anyway and thank you for the useful answer anyway.
