I am experiencing an issue where latency on my Hybrid Drive (SSHD) is always averaging around 500ms up to 10000ms. It's 1TB storage and has been going for around 2 years now however I am pretty certain before performance should start deteriorating this much it should have some more years in it.
The rest of the system configuration is:
i7 8750H
iGPU: Intel UHD 630
Dedicated GPU: RTX 2070 Max-Q
RAM: (2x 8GB) 16GB 2667mhz

I am pretty certain the temps aren't the issue since my GPU normally averages 40C to 55C and my CPU around 50C to 80C
I also know its not my CPU speed or RAM free since i'm normally averaging around 60% - 80% RAM usage and my CPU when idle is around 3.9Ghz and when on games around 3.7Ghz to 3.5Ghz

I have tried fixing this via using Seatools (since the storage that is the issue is a 1TB Seagate Firecuda 5400rpm) and re-installing Windows multiple times and even running the pre-boot drive scanner but none of this has worked.
Aside from getting a new drive are there any other fixes?

Just a guess:
This drive uses high speed flash to buffer access to the slower 5400 RPM underlying HDD.
Flash nand blocks will have a limited number of writes before they can no longer be used.
If, over time, you have used up most of your flash, I would expect to see a slow down.

With lower true ssd prices today, I would consider replacing with a true ssd.
1tb will be about $100.

Let me understand the basic behavior's that are happening here.

On a fresh windows install the disk latency of the disk drive is exceptionally high whilst the computer is idle.

This would indicate an issue with a controller on the storage bus. This normally would be a failing drive but in systems which are overclocked or poorly cooled it can also be caused by failing chipsets, failing CPU's and power supplies. In this case the computer in question is clearly a laptop with a H variant CPU, so no overclocking, however temperatures here are an issue as it is a laptop. A hard drive used in a environment of around 50-60c+ long term is not destined to a live long full life. Whilst 2 years is shorter than the expected life span of the device it is not a faulty device par se due to the environment it operated in. It is well documented the hotter your drive the shorter its life. This affects all types of storage.

I would insert a different drive, if no latency exists on the new drive then your problem is fixed. If it doesn't fix it you are looking at a potential logic board fix or replacement, as PSU with a laptop is unlikely to be the cause of a drive issue.

Not crystal disk mark......crystal disk info.
You need to send the image to a hosting site like IMGUR.
Then post a link to the image.
