Linux to see if the hard drive is an SSD (SSD)

The following switch from Baidu:Recently in preparation for testing, you need to see which machines are mounted SSD hard drives, Google has seen a lot of methods, but all foggy, do not know how to determine. SSD hard disk seems to use the SCSI interface, so according to the name of the drive letter is not to be judged. The last group of Eric God told LSSCSI Tools, try it, very simple, the display is also very direct, share a bit. Nonsense not much to say, direct and result as follows:

[[Email protected]_yf_009_110 ~]# lsscsi[0:0:0:0] Disk SEAGATE st3300657ss ES62-[0:0:1:0] disk ATA INTEL ssdsa2cw16 0362 /DEV/SDA[0:0:2:0] Disk ATA Intel SSDSA2CW16 0362/dev/sdb[0:0:3:0] Disk ATA Intel SSDSA2CW16 0362/dev/sdc[0:1:0:0] Disk Dell VIRTUAL DISK 1028/dev/sdd[3:0:0:0] CD/DVD TEAC DVD-ROM DV-28SW r.2a/dev/sr0

Look at the fourth column to know whether it is SSD hard drive, interested can try

Additional Viewing information:

1. LSHW View all hardware summary information

The following command can view all hardware summary information, and output as an HTML file, the HTML file exported to the computer, directly open, you can clearly see the hardware information:

2. LSSCSI View SCSI Controller device information

You can see information about the RAID card information and all virtual disks as well as the optical drive, and if there is no hardware SCSI controller, it will not return information:
