Is there a Linux command that would allow me to get model information for hard drives? I'm running CentOS.

I want to compare the hard drives on two VPS providers that I use.

  • "Compare" how? Speed? Reliability?

One of these should work:

smartctl --all /dev/sda
hdparm -I /dev/sda

However, if this is a VPS you may not get back reliable data. If that's the case (you get back what's obviously a virtual HDD), there's nothing you can do.

  • Yes, it tells me that is a VMware disk: "Device: VMware Virtual disk Version: 1.0" Thanks.
