On a running system, how do I determine which SATA speed (1.5/3/6)
the disk are currently connected at?

I found this:

https://www.cyberciti.biz/faq/linux-command-to-find-sata-harddisk-link-speed/

None of the methods described work :-( (dmesg, smartctl,
hdparm, /sys/class/ata_link/*/sata_spd ).

$ cat /sys/class/ata_link/link*/sata_spd
6.0 Gbps
1.5 Gbps
<unknown>
<unknown>
$ dmesg | grep 'SATA link'
[ 1.626512] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[ 1.626558] ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300)

Leap 15.0

Weird, same here, but nothing to be seen:

# cat /sys/class/ata_link/link*/sata_spd
<unknown>
<unknown>

# dmesg | grep -i sata
[3.552297] ata1: SATA max UDMA/133 cmd 0x1f0 ctl 0x3f6 bmdma 0x30b0
irq14
[3.552459] ata2: SATA max UDMA/133 cmd 0x170 ctl 0x376 bmdma 0x30b8 irq
15
