Hello,
According to the datasheet this SSD is SATA 3.0 compliant.
But the SMART data of my SSD report it as SATA 2.6.
I reported this problem to the smartmontools developers, which identified that the SSD firmware indeed only report SATA 2.6 compliance.
More information here: https://www.smartmontools.org/ticket/629 https://www.smartmontools.org/ticket/629
Is this a error in the firmware?
Does some OS (Windows / Linux) cannot use the SSD to its full potential due to this?

Hello lecbee,
We will check further on this and will let you know once we have more information.
The SSD is using SATA 3.0 speeds (6.0 Gb/s), so this should not affect the performance of the drive; however, we will confirm why it is showing SATA compliance in the logs.

Thank you for your answer.
FYI, the Intel SSD Toolbox (v3.3.3) also doesn't claim SATA 3.0 compliance.

Hello,
We received confirmation that the SSD is compliant with SATA 3.0 standards (as noted, it works at 6 Gbps, which would not be possible with SATA 2.6).
It shows as SATA 2.6 due to a reporting issue that causes the drive not to show the details correctly (Bit 5 of word 222).
We have forwarded this to the proper resources for further review, however, this condition does not have any impact in the functionality of the SSD.

I have SSDSC2BB160G4 SSD which is S35x0/3610/3700 series SSD. From rhel7.1(3.10.0-229.el7.x86_64), the output from 'smartctl --identify=wb /dev/sda | grep -i sata' command is:
[root@test-0001 ~]# smartctl --identify=wb /dev/sda | grep -i sata

what is the meaning of "0" from SATA3.1/3.0 lines?, I think that '0' value is 'disabled' meaning.
