I have a server where I will be updating the Adaptec RAID controllers firmware and drivers soon, and so I was arcconf to check a few things.

The four disks are all the same model configured as a RAID10 volume. In running the GETCONFIG of arcconf, I was a bit surprised that one of the drive is running at 3.0gb/s instead of 6, like the other drives.

What could be the reason for this, and is there a way to get it to run at 6gb/s?

Most probably ATA (DATA) cable is damaged and maximum throughput of it is 3 GB/s. Try to change the cable or if it's a hot swap use the different slot. Moreover, it is doesn't make any differences in 5.4k RPM drive and you will still get decent performance, so it will make virtually NO difference in your performance.

    Hmm, the cable looks like this: https://binged.it/2PeuSMa So I'd have to disconnect all the drives. Would a cable like this still have one faulty SATA end? – Andy Aug 14 '18 at 23:19

    It might. You can get these SFF-8087-to-SATA breakout cables everywhere. – Zac67 Aug 16 '18 at 20:14
