Ubuntu16.04中查看硬盤的型號和讀取速度

最近在測試FTP服務器，上傳和下載的速度與不少因數有關，其中，硬盤的讀取速度就是其中不一樣的區別點，我同時用了三臺不用的服務器架設FTP服務,一臺是出來ftp服務外還含平臺其餘管理軟件，一臺是全新的系統，只使用FTP服務；另一個是安裝了固態硬盤的演示機器（外星人機器，一個小方盒子，聽過價格將近1w）。

 

查看硬盤的讀取速度：

hdparm -t /dev/sda:解釋，這個的sda是安裝Ubuntu系統的根目錄的掛載點。

不一樣的機器掛載點不同

首先DF查看

三臺服務器分別爲：

最先安裝那臺服務器的根目錄掛載點爲：/dev/sda1；

另外兩臺分別爲：/dev/dm-0和/dev/mapper/ubuntu--vg-root(外星人)

相對應的查看他們的讀速度則要改成：hdparm -t /dev/mapper/ubuntu--vg-root

 

硬盤數量、大小：sudo fdisk -l |grep "Disk /dev/sd"
硬盤型號：sudo hdparm -i /dev/sda |grep "Model"

linux下怎樣查看硬盤型號和硬盤序列號

 

hdparm -i /dev/hda

 

顯示硬盤的相關設置

[root@cnscn ~]# hdparm /dev/sda

/dev/sda:

IO_support = 0 (default 16-bit)

readonly = 0 (off)

readahead = 256 (on)

geometry = 19929［柱面數］/255［磁頭數］/63［扇區數］, sectors = 320173056［總扇區數］, start = 0［起始扇區數］

 

.顯示硬盤的柱面、磁頭、扇區數

[root@cnscn ~]# hdparm -g /dev/sda

/dev/sda:

geometry = 19929［柱面數］/255［磁頭數］/63［扇區數］, sectors = 320173056［總扇區數］, start = 0［起始扇區數］

 

.評估硬盤的讀取效率

[root@cnscn ~]# hdparm -t /dev/sda

/dev/sda:

Timing buffered disk reads: 166 MB in 3.03 seconds = 54.85 MB/sec

[root@cnscn ~]# hdparm -t /dev/sda

/dev/sda:  www.2cto.com  

Timing buffered disk reads: 160 MB in 3.01 seconds = 53.11 MB/sec

[root@cnscn ~]# hdparm -t /dev/sda

/dev/sda:

Timing buffered disk reads: 166 MB in 3.00 seconds = 55.31 MB/sec

 

.評估硬盤快取的讀取效率

[root@cnscn ~]# hdparm -T /dev/sda

/dev/sda:

Timing cached reads: 3784 MB in 2.00 seconds = 1894.60 MB/sec

[root@cnscn ~]# hdparm -T /dev/sda

/dev/sda:

Timing cached reads: 3816 MB in 2.00 seconds = 1909.06 MB/sec

[root@cnscn ~]# hdparm -T /dev/sda

/dev/sda:

Timing cached reads: 3728 MB in 2.00 seconds = 1866.29 MB/sec

 

.檢測IDE硬盤的電源管理模式

[root@cnscn ~]# hdparm -C /dev/sda

/dev/sda:

drive state is: standby [省電模式]

.顯示IDE硬盤的內定硬件規格

[root@cnscn ~]# hdparm -i /dev/sda

 

.直接檢測硬盤的硬件規格

[root@cnscn ~]# hdparm -I /dev/sda
