Is there a command to view hard drive specs

I noticed that my Ubuntu is lagging EXTREMELY badly but only the first time I do things after what I did gets loaded into RAM the lag stops totally. I ran some tests and I guess one of my laptop hard drives is borked.

Im assuming that I have to replace the drive, is there some command I can issue to see the exact specs on the drive so I can then buy it online?

I don't want to have to open up the laptop, find the specs. Then open it again when the new drive arrives.

Solution 1:

smartctl command from smartmontools package is what you want for that

% sudo smartctl -i /dev/sda

Solution 4:

You can use lsblk, it has a ton of options that you can use e.g.:

lsblk -o MODEL,SIZE,NAME -d

which gives this result in my case

MODEL              SIZE NAME
Samsung SSD 850  232.9G sda
Samsung SSD 850  931.5G sdb

Solution 5:

$ lsblk

The command lsblk by default will list all block devices in a tree-like format. Type lsblk --help to see more options
