    Intel 750 Series 400GB PCIe NVMe 3.0 SSD slowing down

      Hi ,

       

      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

          Hello randomaccess,

           

          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.
