Linux Command To Find SATA Link Speed Such as 1.5 / 3.0 / 6.0 Gbps [ Hard Disk ]

Best/Tutorial

You can use the hdparm utility to find the SATA link speed of a hard disk in Linux. Here's how:

  1. Open a terminal window.

  2. Run the following command: sudo hdparm -I /dev/sda | grep "SATA revision" (replace /dev/sda with the appropriate device name for your hard disk).

  3. The output will show the SATA revision, which corresponds to the SATA link speed. For example:

 
SATA revision: SATA 3.0, 6.0 Gb/s (current: 3.0 Gb/s)

In this example, the hard disk supports SATA 3.0, with a current speed of 3.0 Gb/s. The possible values for SATA revision are SATA 1.0 (1.5 Gb/s), SATA 2.0 (3.0 Gb/s), and SATA 3.0 (6.0 Gb/s).
