Re: hdparm et mesure udma66

Bonjour,

Je n'arrive plus a trouver le thread, mais il me semble qu'il y a
quelque temps, quelqu'un cherchait des stats sur les mesures de vitesse
des disques.

Chez moi:

/dev/hdc= Western Digital WDC205BA
/dev/hdd= Maxtor 5T020H2

Je suis plutot content de ma WD IDE: meme les meilleurs disques scsi
actuels arrivent a 55 Mo/s en debut de piste et 35 Mo/s en fin de piste
:-).
