Bonjour et merci,
Je ne connais pas hdparm mais j'ai testé les commandes suivantes :
(Lecture sur disque)
# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 118 MB in 3.05 seconds = 38.73 MB/sec
(Lecture sur cache)
# hdparm -T /dev/sda
/dev/sda:
Timing cached reads: 2122 MB in 2.00 seconds = 1062.20 MB/sec
(flag d'utilisation DMA)
# hdparm -d /dev/sda
/dev/sda:
HDIO_GET_DMA failed: Inappropriate ioctl for device
Je pense que les informations suivantes peuvent peut être être intéressantes ? :
# hdparm -I /dev/sda
/dev/sda:
