smartctl + como encontrar a taxa de transferência de XXX MBps no disco

  • 772

queremos saber - Com que rapidez um único volume de armazenamento pode ler ou gravar, em Megabytes por segundo

por exemplo - taxa de transferência de 125 MBps.

então usamos o smartctlcomando para capturar a taxa de transferência de XXXMBps. valor

mas não encontramos esta informação do smartctl

alguma outra opção?

 smartctl -a /dev/sdb
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.10.0-514.26.2.el7.x86_64] (local build)

    Este...

    $ lsblk -ap -e7 -o NOME, PONTO DE MONTANHA, FSTYPE, RÓTULO, RO, RM, ESTADO, TIPO, TAMANHO, MODELO
NOME DE MONTAGEM FSTYPE LABEL RO RM ESTADO TIPO TAMANHO MODELO
...
    ... dará uma boa tabela sobre os dispositivos disponíveis (excluindo loop:s).

    Escolha uma coisa da coluna NAME e use como $dev aqui...

    sudo hdparm -Tt $dev

    Ah, e você precisa disso:
    $ sudo apt install hdparm
