Hello dehLord,

 

 

Thanks for posting in our communities. We understand that you're experiencing a relatively slow sequential write speed on your Intel® SSD E 5400s Series.

 

 

In order to better assist you, please provide us with following information:

 

 

- What tool are you using for benchmarks?

 

- Please download and run the https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-?product=91... Intel® System Support Utility and share the resulting report with us. This will provide us with the exact SSD model and your system general specs.

 

 

Best regards,

Hello,

I used AS SSD Benchmark and CrystalDiskMark. I attached the file you requested.

Hello dehLord,

 

 

Thanks for your reply.

 

 

The https://ark.intel.com/products/94440/Intel-SSD-E-5400s-Series-120GB-2_5in-SATA-6Gbs-16nm-TLC Intel® SSD E 5400s Series (120GB, 2.5in) official benchmark sequential write is up to 400 MB/s. Please note that these results were taken from a fresh OS installation (Windows 7* SP1), with the SSD connected as a secondary unit and no data on it.

 

 

From the log provided, we can see the Intel® SSD E 5400s Series is your boot drive. That plus several processes running on the back will affect the results. To obtain benchmark numbers closer to the advertised, we recommend to run a secure erase on the SSD and connect it as a secondary unit if possible.

 

 

Let us know if there's anything else we can do for you.

 

 

Best regards,

Yes, i have one more question: how do i proceed to reinstall my windows? I just have to do a normal format or i need to use secure erase?

Hello dehLord,

 

 

A secure erase is recommended in this case. However, since this is your current boot device, Windows* will not allow you to wipe the SSD.

 

 

If you can connect it to a different system or boot from a different drive, you can use Microsoft DiskPart* to secure erase the SSD as shown https://www.intel.com/content/www/us/en/support/articles/000022179/memory-and-storage.html here. If this is not an option, you may proceed with a fresh OS installation.

 

 

Please bear in mind that if you're planning to keep using the Intel® SSD E 5400s Series as your boot drive, the results might not vary from the current installation.

 

 

Best regards,
