That's not the speed, that's the negotiated transfer rate.
Since the drive can't read or write more than 130MB/s anyway -- about 1/3
of the interface speed -- the drive is probably not actually affected.
Also, note that it uses 4096 byte sectors but pretends that they
are 512.
Possible reasons for negotiating 3Gb/s vs 6Gb/s: bad cable, or
cable making tenuous contact, is the number one suspect.
