a few days ago I installed a Samsung SSD 860 EVO hard disk in place of the cd player via sata3 Salcar caddy in my Inspiron 5767 with Windows 10 Pro.
After the replacement, everything works fine, but Samsung's Magician software recognizes the SSD disk as sata 2 (3Gb) instead of sata 3 (6Gb) (showing a warning that indicate the support and the availability of the sata 3 interface).
Using peripheral control software such as HardwareInfo 64bit, the drive controller would seem to correctly support the sata 3 protocol but still recognize the device as sata 2.
Drive Controller: Serial ATA 6Gb / s @ 3Gb / s
Going to check the SATA AHCI controller results this:
Interface Speed Supported: Gen3 6.0 Gbps
Sata Port # 0 Current Interface Speed: Gen3 6.0 Gbps (Internal original HDD)
Sata Port # 1 Current Interface Speed: Gen2 3.0 Gbps (SSD Drive through caddy)
The BIOS is updated to version 1.2.4 of 02-Apr-2018
The SATA AHCI Controller (Intel (R) 6th Generation Core Processor Family Platform I / O Controller Drivers) are manufactoring from Microsoft with version 184.108.40.2060 of 13-Sep-2016 and Microsoft Update not have any newest driver.
How can this problem be solved without having to open the pc and replace the hdd disk with that ssd?
Thanks so much
It's clear the optical drive slot runs SATA 3G -- so the answer to your last question is, it cannot - you must swap the drives if you want them to run at full speed.
OK, but... if all the software report that the sata port support the sata 3, why the ssd cannot operate at 6Gb ? All the components support the sata 3 protocol.
Chances are the port connected to the optical drive is locked at 3G/s -- the optical drive would not need more. It may simply be the way the mainboard is designed - the ODM would have no reason to wire the port for high performance an optical drive would never need. They could have used a board design from an older model - no way to know unless you can somehow find and speak to the designers.
It's likely due to the mainboard design, and cannot be software-unlocked. Since there's no need for 6G to the optical interface, the bandwidth was likely allocated elsewhere.
