Intel Rapid Storage Techonology

[strv]

I connect a SATA device, which support NCQ but only one queue(not 32 queues).

Before I installed iRST(Intel Rapid Storage Technology), host(PC) does not issue Read/Write FPDMA command to the device.

However after installing iRST, host(PC) issues Read/Write FPDMA coomand.

My question is

Who(or How) determines to issue Read/Write FPDMA command to such a device(only one queue support)?

Hello strv,  

Thank you for posting on the Intel® communities.   

In order to better assist you, please provide the following:  

1. Run the Intel® System Support Utility (Intel® SSU) to gather more details about the system.  

· Download the Intel® SSU and save the application on your computer: https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-

· Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".  

· To save your scan, click Next and click Save.  

2. Provide RST report: https://www.intel.com/content/www/us/en/support/articles/000006351/technologies.html

3. Is this a Desktop/Laptop/Server computer?

4. What is the make and model of the system?

5. What is the Intel® RST Driver version installed on the system?

6. Do you have a RAID configuration? If so, which one?

7. What is the primary use of Intel RST on this system?

Hello strv, 

Based on the reports looks like you have a storage device SVRC-C600SA, and I would like to gather more details. Please, help me with the following:

1. What does happen if you connect SSD/HDD directly to the computer?

2. Have you tried contacting the device manufacturer (SSD/HDD)?

3. Have you performed BIOS and/or firmware updates? If not, try to perform them.
