Combinando SDA e SDB

1

Eu comprei recentemente um laptop para instalar o Ubuntu no. Pelo que entendi, há 1 SSD dentro com um tamanho de 256GB. No entanto, ao tentar instalar o Ubuntu, eu recebo duas partições, SDA e SDB de tamanho igual.

Se eu instalar no SDA, isso limitará o meu tamanho "total" do Ubuntu a 128 GB? Como faço para combinar os dois para usar um tamanho total de 256 GB?

Estou errado em assumir que há 1 SSD de tamanho 256?

Obrigado.

Como você pode ver, / dev / sda está no canto superior direito no menu suspenso, / dev / sdb pode ser acessado de lá também.

As saídas hdparm mostram claramente que você tem 2 ssd-s em seu laptop. Então eu decidi procurar as especificações do seu laptop, e não há mistério, você tem a versão Asus UX31LA-C4018H, que vem com SSD-s de 2x128 GB. Ver, por exemplo, aqui

Se você ainda quiser combinar as unidades, então você deve usar o LVM. Por favor, veja este Q & amp; A para mais informações sobre como configurar um LVM.

link mostra que a configuração do seu Zenbook é, na verdade , dois cada SSDs de 128GB. Portanto, gostaria de configurar o Ubuntu para usar sda para o sistema operacional e programas (root), bem como a partição de swap. Em seguida, crie uma nova partição usando todos os sdb como / home e é para onde seus dados serão enviados.

A configuração original, RAID0, dá mais velocidade (boa para Windoze), mas menos confiabilidade.
