Bonjour et merci, |
| 10 |
|
| 11 |
Je ne connais pas hdparm mais j'ai testé les commandes suivantes : |
| 12 |
(Lecture sur disque) |
| 13 |
# hdparm -t /dev/sda |
| 14 |
|
| 15 |
/dev/sda: |
| 16 |
Timing buffered disk reads: 118 MB in 3.05 seconds = 38.73 MB/sec |
| 17 |
(Lecture sur cache) |
| 18 |
# hdparm -T /dev/sda |
| 19 |
|
| 20 |
/dev/sda: |
| 21 |
Timing cached reads: 2122 MB in 2.00 seconds = 1062.20 MB/sec |
| 22 |
(flag d'utilisation DMA) |
| 23 |
# hdparm -d /dev/sda |
| 24 |
|
| 25 |
/dev/sda: |
| 26 |
HDIO_GET_DMA failed: Inappropriate ioctl for device |
| 27 |
|
| 28 |
|

Je pense que les informations suivantes peuvent peut être être intéressantes ? : |
| 30 |
|
| 31 |
# hdparm -I /dev/sda |
| 32 |
|
| 33 |
/dev/sda: |
