Tasa de transferencia de archivos por usb muy baja

Olvidé comentar que los discos duros en cuestión estan en ntfs, no he
probado otros fs por usb.
Yo también lo espero Jorge, gracias.
Es para OpenSUSE, no se si servirá para Ubuntu, pero yo no he notado cambio.
El comando «rchal restart» tampoco me funcionó.
He encontrado este archivo en mi SO:

Borré las lineas de sync y dirsync pero tampoco obtuve cambios en la
velocidad de transferencia.

Parte del resultado del comando lshal: (la que involucra al disco duro en
cuestión y al aparato que uso para conectarlo por usb.

Como se puede ver en esta última parte, a pesar de borrar las lineas
mencionadas antes sigue contemplando las opciones «sync y dirsync» para
montar el disco, pero si lo consulto con «mount» me dice lo siguiente:

/dev/sdb1 on /media/320gb-ntfs type fuseblk
(rw,nosuid,nodev,allow_other,blksize=4096)

Estoy un poco mareado de tanto buscar y probar con hal, ¿Alguna idea?
