If the VPS hard disk is an SSD solid state disk, the speed measurement in the normal way may not really reflect the performance of the SSD,
We can install the hdparm tool on the vps for testing
The steps are as follows:
Execute the following command to install hdparm
yum install hdparm -y
input fdisk -l List all partition tables
Use hdparm - t to test the speed of a hard disk, such as
hdparm -t /dev/vda1
