According to your post, the SSD is getting around 120 MB/s sequential write, we would like to ask you, what application are you using to test the SSD?
Here are the http://ark.intel.com/products/94420/Intel-SSD-540s-Series-120GB-2_5in-SATA-6Gbs-16nm-TLC specs of the drive, where you can check the estimated sequential read & write. For testing, we used the IOmeter* software.
If you have any more questions, please let us know.
Thanks for answering. The software was used AS SSD Benchmark 1.9.5986 . According to the specifications intel page sequential write speed dberia be 400mb / s . The bios was set to AHCI mode before installing Windows x64 and intel® Solid State Drive Toolbox according to the firware is updated .
We use IOmeter* to perform the tests in our SSDs, this because we can handle the queue depth on it and provide valid information.
Please find in this http://www.intel.com/content/dam/support/us/en/documents/ssdc/hpssd/ssd-750/sb/intel_ssd_750_series_... link how to configure the program to properly provide scores.
If you need to download IOmeter*, here is the http://www.iometer.org/doc/downloads.html link.
As well, we do know that CystalDiskMark is accurate at providing scores, if you want to try it here is the https://osdn.jp/projects/crystaldiskmark/downloads/65730/CrystalDiskMark5_1_2-en.exe/ link.
Please let us know if you require further assistance.
Thanks for the reply.
Could you please attach the *.csv file in order to verify the settings?
Also, please let us know if the test was for reading or writing, this because you should run two tests, one for sequential read and the other one for sequential write. Please attach the two files.
If you have questions, please let us know so we can assist you.
We are following up and we would like to know if you can share the files with us or if you need any further assistance.
We will be waiting for your response.
