Yop yop la liste !
Ben je vous écris pour savoir si il y a moyen d'optimiser (avec la commande
hdparm) mon tout nouveau disque dur IBM de 80Go ...
Voici les benchmark:
[09:48:14][root@slack:/home/blenderman]# hdparm -tT /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 0.87 seconds =147.13 MB/sec
Timing buffered disk reads: 64 MB in 30.35 seconds = 2.11 MB/sec
Ce qui n'est pas très avantageux ... J'aurais peut etre du acheter un Maxtor
...
