Re: [SOLVED] How to switch SSD to 6 Gb/s mode?

Final solution: As usual, I am a dumb ass. My motherboard has only two SATA 3 ports, and they are taken by the HDD's.

Glad you have finally sorted it!
As frostschutz previously mentioned in an earlier post, connecting one of your HDD's to a slower 3Gb/s port and the SSD to a 6Gb/s port would be beneficial to take advantage of the SSD read/write speed.

Re: [SOLVED] How to switch SSD to 6 Gb/s mode?

It seems like Unix/Ubuntu AHCI auto negotiates the best speed as per CPU /Chipset / HDD hardware capabilities. I would recommend dualboot to windows to test out that configuration.

My Scenario: Upgraded my Dell AIO 2320 with CPU i5-2400S with ADATA SX850 SDD.
Transferred existing WD 1TB HDD to my Desktop with CPU i5-8400.
Both HDD are capable of SATA3 6Gbps.
Same versions of Ubuntu 24 on both machines.
On Ubuntu 24, Desktop HDD shows AHCI 6.0Gpbs, AIO SSD shows AHCI 3.0Gbps.
On Windows11, the ADATA SSD toolbox also shows SATA 3.0Gbps, AIO has dual boot windows 11 and Ubuntu24.
