Re: [opensuse] how to determine actual SATA speed ?
Le 21/03/2019 à 10:50, Per Jessen a écrit :
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 ).

The boards have an ICH7R controller which is 3Gbps, so I'm pretty
certain about the speed, but surely there is a way to tell?



# hdparm -t /dev/sda

/dev/sda:
Timing buffered disk reads: 810 MB in 3.00 seconds = 269.92 MB/sec
linux-wacn:/home/jdd # hdparm -T /dev/sda

/dev/sda:
Timing cached reads: 26492 MB in 1.99 seconds = 13291.32 MB/sec
linux-wacn:/home/jdd #

jdd
