How to check if an attached SSD device is SATA or PCIe on Linux?

Question

I have a machine with both SATA and PCIe SSDs attached. Is there a set of Linux commands (on Ubuntu or CentOS) that I can use to check if a given SSD is SATA or PCIe?

Answer 1

lsblk -io NAME,TYPE,SIZE,MOUNTPOINT,FSTYPE,MODEL

will identify all the block devices, i.e., drives. Then, run

sudo hdparm -I /dev/sd*X* | grep SATA 

where X is each drive letter found. If the result contains SATA, well, it's the SATA drive.

Alternatively,

lspci

will identify all the PCI devices, including PCIe.

Or, you can look for the NVMe logo on the drive.

Use lshw. It'll show disk type in the description field

$ sudo lshw -class disk
