SATA 6Gbps Hard Drive detects 1.5Gbps

lancededcena · Feb 20, 2015

Hello, I have a Seagate ST2000DM001-1CH1 2TB Hard Drive that only detects that it is connected to a SATA 1 Port rather than a SATA 3 Port.

I am using Ubuntu by the way.

Perhaps you're not using a SATA 3 cable? Though I'm not sure if SATA1/2 or 3 cables are not just a marketing gimmick

VicVega1 :

I am using the cable provided by Gigabyte which is SATA 3.

SATA cables are universal. Are you sure you're using a SATA3 port? Also notice where it says "HW SATA SPD Limit: <unknown>", did you install motherboard drivers?

leo2kp :

Correct me if I am wrong, but Gigabyte doesn't provide motherboard drivers for Linux, and I checked the additional drivers and the only drivers there are for the Nvidia Graphics Drivers.

Sometimes you can get chipset drivers from Intel or AMD.

leo2kp :

Intel Chipset drivers are preinstalled by default in Ubuntu.

I admit I don't know much about Linux, but you would expect that it would be able to detect the maximum speed if the chipset that he has has drivers in Ubuntu. It seems like it's playing it safe and keeping it at 1.5G because it doesn't know it's a 3.0 port.

Just turned my computer on, started detecting 6Gbps speed.
