I am savaging an old T5400 workstation, upgrading HDD to SSD (Samsung EVO 850), but noticed the SSD is only running at SATA 1 speed, at practical speed of 50MBps. Samsung EVO SSD should be running at SATA3, or close 200-300MBps. Using HWiNFO, dignose the drive is running at 1.5gbps, which is SATA1 speed. The controller is SAS 6iR, which at least support SATA2 speed.

Did research and found solution, Post here to share with rest of community.

Original Post Info from Dell forum: https://www.dell.com/community/PowerEdge-HDD-SCSI-RAID/SAS-6-iR-Integrated-SAS-SATA-SSD-Negotiated-speed-PE1950/td-p/4403779

  1. Dell SAS 6ir controller does support SATA2 at 3gbps speed. However the negotiated speed with Samsung EVO SSD is only at 1.5gbps. Real file copy speed around 60MBps.
  2. Can use LSIUtil_1.62 to config SAS controller to set minimum speed at 3gbps.
  3. LSIUtil_1.62 (windows version) can be downloaded at http://www.dzhang.com/files/blog/2013/03/LSIUtil_1.62.zip
  4. Download and extract all content.
  5. Run cmd window as admistrator, cd to extract directory, run LSIUtil.exe
  6. Choose your device, select option 13,changeMinRate to 3.0 for all PhyNum
  7. Save and Quit, and reboot
  8. Verify speed is at 3gbps with HWiNFO. Real file copy speed approaching 200MBps.
