I am using Intel 750 Series 400GB PCIe NVMe 3.0 SSD. I have noticed that it is not that snappy recently.
I have run the AS SSD Bench mark & I can see the low
Initially this was the test result.
It is getting slower and slower.
I have attached the File from Intel SSD toobox

Performance Enhancing Tips
Tip 1803 : Disk firmware update available. To update, visit the manufacturer's website.
Tip 2 : Double-click tip or press Enter while a tip is selected for more information about the tip.
Please use Intel® SSD Toolbox and run the Intel® SSD optimizer function to your drive, then check if this improves the behavior.
Also, check if TRIM is enabled in Windows*. Open a Command Prompt with Administrative privileges and executer the following command:
fsutil behavior query DisableDeleteNotify
If the result is '0', it means that TRIM is enabled.
If the issue persists, please consider the following:
Have you tried running standard maintenance tools on your drive? (Disk cleanup and Error-checking)
Have you noticed any other issues on the system? Application issues, check for viruses, etc.
I used the Intel SSD Optimizer, Trim is enabaled. I have done the full virus scan, it was clean.
Windows is unusable , it is freezing all the time, probably waiting to finish writing something.
I cloned the disk on to another SSD which is attached to a areca ARC-1882X Controller Card. I booted from the SATA SSD.
Windows is running smoothly & everything is back to normal.
Here is the benchmark. You can notice Intel 750 is D Drive. You can notice 4K-64Thrd is way too low.
There is definitely something wrong with the Intel 750 PCIE NVME SSD. I am planning to return it if there is no resolution found.
I had faced a similiar problem with Samsung 840 Evo drive for which Samsung released a fix. It was to do more with the read than write.
Here I think it is the write problem.
I deleted everything from the SSD, I used the Intel Optimizer & left it running for 24 hours, but there is no major improvement.
