How To Find Out Hard Disk Specs / Details on Linux
Can you tell me a Linux command to find out information about my hard disk such as description, product name, bus type, size, and cache memory size under Linux operating systems using command line options?
Linux comes with various commands to find out information about your hard drive. I recommend hdparm command, which provides a command-line interface to various hard disk ioctls supported by the stock Linux ATA/IDE device driver subsystem. This command reads/request identification information such as disk size, description, and much more directly from the drive, which is displayed in a new expanded format. Let us see various Linux disk info commands to print hard disk drive details on screen.
Use the hdparm command to find hard disk drive specification on Linux
Open the terminal and type the following command to find information about /dev/sda:
hdparm -I /dev/sda
# OR
sudo hdparm -I /dev/sda
Here is what I see:

lshw command
You need to install lshw command using apt-get or yum command. To display all disks and storage controllers in the system, enter:
lshw -class disk -class storage

Finding Out Linux Disks Names Only
The following lshw command will quickly list installed disks including CD/DVD/BD drivers:
lshw -short -C disk
Sample outputs:
H/W path Device Class Description
========================================================
/0/100/1f.2/0 /dev/sda disk 500GB TOSHIBA MK5061GS
/0/100/1f.2/1 /dev/cdrom disk BD-RE UJ232A
/0/100/1f.2/1/0 /dev/cdrom disk
/0/100/1f.2/0.0.0 /dev/sdb disk 500GB ST9500420ASG
Another option so to run the fdisk command as follows:
fdisk -l
Using lsblk command to find out Linux hard disk information
Run the **lsblk88 command as follows to lists information about all available or the specified block devices:
lsblk
lsblk /dev/DISK
lsblk /dev/sda
So I have two NVMe SSD in RAID-1 mode with encrypted partitions:
nvme0n1 259:0 0 953.9G 0 disk
├─nvme0n1p1 259:1 0 953M 0 part /boot/efi

├─nixcraft-swap 253:1 0 119.2G 0 lvm [SWAP]
└─nixcraft-root 253:2 0 829.9G 0 lvm /
Another option is to run the following ls command to list all disks and their names:
ls -lF /dev/disk/by-id/
Linux show block device such as hard disk drive attributes
Open the terminal app and then type the blkid command:
blkid
/dev/sda1: UUID="35D0-69B0" TYPE="vfat" PARTUUID="50f81f2e-9c4c-43ce-896d-7a55bee67397"
/dev/sda2: UUID="985b0131-765b-4d1e-94fa-8c86491dad4d" TYPE="ext4" PARTUUID="00
smartctl command
The smartctl command act as a control and monitor Utility for SMART disks under Linux and Unix like operating systems. Type the following command to get information about /dev/sda (SATA disk):
smartctl -d ata -a -i /dev/sda
