Just installing an SSD into an HP Probook 6560b and noticed that Samsung Magician states that the drive is connected with SATA 2. I looked in the BIOS and SATA 2 (3.0gbps) was chosen, rather than SATA 3.
This was the default setting.
Why would SATA 2 be default rather than 3? I realise HDD will generally not saturate SATA 2 or benefit from 3, but why not leave 3 as the default instead? Does SATA 3 use more power, or am I missing something?
