# 1，linux硬盘读写性能测试 #

apt install hdparm -y

*  不使用缓存，测试硬盘

# hdparm -t /dev/sda
    
    /dev/sda:
     Timing buffered disk reads: 676 MB in  3.00 seconds = 225.33 MB/sec

*  查看硬盘缓存

# hdparm -I /dev/sda | grep buffer
    	cache/buffer size  = unknown

*  查看硬盘写缓存是否打开

# hdparm -W /dev/sda
    
    /dev/sda:
     write-caching =  1 (on)

*  关闭硬盘写缓存

# hdparm -W  0 /dev/sda

*  打开硬盘写缓存

# hdparm -W  1 /dev/sda

# hdparm -T /dev/sda
    
    /dev/sda:
     Timing cached reads:   27920 MB in  2.00 seconds = 13976.25 MB/sec

# hdparm -tT --direct /dev/sda
    
    /dev/sda:
     Timing O_DIRECT cached reads:   1014 MB in  2.00 seconds = 506.59 MB/sec
     Timing O_DIRECT disk reads: 748 MB in  3.00 seconds = 248.93 MB/sec

# hdparm -t --direct /dev/sda
    
    /dev/sda:
     Timing O_DIRECT disk reads: 692 MB in  3.01 seconds = 230.10 MB/sec

*  测试硬盘读取速度

# for i in 1 2 3; do hdparm -t --direct /dev/sdb; done
    
    /dev/sdb:
     Timing O_DIRECT disk reads: 692 MB in  3.00 seconds = 230.37 MB/sec
    
    /dev/sdb:
     Timing O_DIRECT disk reads: 754 MB in  3.01 seconds = 250.80 MB/sec
    
    /dev/sdb:
     Timing O_DIRECT disk reads: 756 MB in  3.00 seconds = 251.88 MB/sec

# 2，固态硬盘 #

# hdparm -t /dev/nvme0n1
    
    /dev/nvme0n1:
     Timing buffered disk reads: 9176 MB in  3.00 seconds = 3058.37 MB/sec
