USB 3.0 gravação lenta Ubuntu 15.10

Question

Eu tenho um Gateway NE512 com USB 3.0, no Windows, a velocidade de leitura no meu Kingston DTR3.0G2 32GB é de aproximadamente 50-70 MB / S e leitura de 120-140 MB.

No Ubuntu com o kernel 4.2.0-27-generic esta é a velocidade na porta 3.0 com o mesmo dispositivo (leia-se: 23.8MB / s write: 76.4MB / s)

Imagem NE512 do Gateway de Teste de Velocidade USB 3.0:

saída de lsusb:

Alguém poderia me ajudar a resolver esse problema?
