前言：將固態硬盤裝到電腦，ubuntu系統須要格式化並掛載才能正式使用ubuntu
將固態裝在電腦上後，打開後端vim
1：查看現有硬盤分區及掛載狀態後端
命令 ：df -h
沒有新增的SSD固態硬盤服務器
2：查看服務器全部安裝的硬盤狀態（包括已安裝和未安裝的）ide
命令: fdisk -l
此時已經安裝的磁盤，可是沒有分區，先分區ui
3, 將磁盤分區，分一個區掛載到根目錄下spa
命令：fdisk /dev/sdb (該目錄是上面未安裝的磁盤目錄）
輸入完命令後按回車或者直接按回車就行了3d
4 在查看磁盤分區狀況code
命令：fdisk -l
如今已經有新的分區了orm
5 格式化分區
命令： mkfs -t ext4 -c /dev/sdb1
# -t 制定要把磁盤格式化成什麼類型
# -c 在創建文件系統以前檢查環道，要等一段時間，新硬盤通常不須要
6 掛載新磁盤
1） 先在根目錄下新建一個目錄做爲一個掛載點
命令 ：mkdir /ssd
在執行掛載命令
命令 ： mount /dev/sdb1 /ssd
顯示掛載成功
7 .設置開機自動掛載
命令 : vim /etc/fstab
或者 gedit /etc/fstab
在文件最後添加 /dev/sdb1 /ssd ext4 defaults 0 0
安裝完成後，還能夠使用相關命令查看硬盤的讀寫速度
查看硬盤的讀取速度
命令： hdparm -t /dev/sda 這個sda是安裝ubuntu系統的根目錄的掛載點
不一樣機器的掛載點不同。使用命令查看掛載點
命令: df -TH
Filesystem下面的路徑就是掛載點
硬盤數量、大小：sudo fdisk -l |grep "Disk /dev/sd"
硬盤型號：sudo hdparm -i /dev/sda |grep "Model"
liunx下查看硬盤型號和硬盤序列號:
命令 ： hdparm -i /dev/sdb
顯示硬盤的相關設置
root@:~# hdparm /dev/sdb
/dev/sdb:
multcount = 1 (on)
IO_support = 1 (32-bit)
readonly = 0 (off)
readahead = 256 (on)
geometry = 60801 [柱面數] /255 [磁頭數] /63 [扇區數], sectors = 976773168 [總扇區數], start = 0 [起始扇區數】
顯示硬盤的柱面，磁頭，扇區數
評估硬盤的讀取效率
命令 ： hdparm -t /dev/sdb1
評估硬盤快取的讀取效率
命令 ： hdparm -T /dev/sdb1
直接檢測硬盤的硬件規格
root@:~# hdparm -I /dev/sdb
