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: ATA device, with non-removable media Model Number: FUJITSU MHV2080BH PL Serial Number: NW99T6729MWJ Firmware Revision: 00000029 Standards: Used: ATA/ATAPI-7 T13 1532D revision 4a Supported: 7 6 5 4 & some of 8 Configuration: Logical max current cylinders 16383 16383 heads 16 16 sectors/track 63 63 -- CHS current addressable sectors: 16514064 LBA user addressable sectors: 156301488 LBA48 user addressable sectors: 156301488 device size with M = 1024*1024: 76319 MBytes device size with M = 1000*1000: 80026 MBytes (80 GB) Capabilities: LBA, IORDY(can be disabled) Queue depth: 32 Standby timer values: spec'd by Standard, no device specific minimum R/W multiple sector transfer: Max = 16 Current = 16 Advanced power management level: 128 Recommended acoustic management value: 254, current value: 254 DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5 Cycle time: min=120ns recommended=120ns PIO: pio0 pio1 pio2 pio3 pio4 Cycle time: no flow control=240ns IORDY flow control=120ns Commands/features: Enabled Supported: * SMART feature set Security Mode feature set * Power Management feature set * Write cache * Look-ahead * Host Protected Area feature set * WRITE_BUFFER command * READ_BUFFER command * DOWNLOAD_MICROCODE * Advanced Power Management feature set SET_MAX security extension * Automatic Acoustic Management feature set * 48-bit Address feature set * Device Configuration Overlay feature set * Mandatory FLUSH_CACHE * FLUSH_CACHE_EXT * SMART error logging * SMART self-test * General Purpose Logging feature set * WRITE_{DMA|MULTIPLE}_FUA_EXT * IDLE_IMMEDIATE with UNLOAD Disable Data Transfer After Error Detection * SATA-I signaling speed (1.5Gb/s) * Native Command Queueing (NCQ) * Host-initiated interface power management * Phy event counters DMA Setup Auto-Activate optimization Device-initiated interface power management * Software settings preservation * SMART Command Transport (SCT) feature set * SCT LBA Segment Access (AC2) * SCT Error Recovery Control (AC3) * SCT Features Control (AC4) * SCT Data Tables (AC5) Security: Master password revision code = 65534 supported not enabled not locked frozen not expired: security count not supported: enhanced erase 80min for SECURITY ERASE UNIT.
