Sata 표준 속도는 다음과 같음

 

SATA REVISION => SPEED ({Gbit|MB}/s)

SATA revision 1.0 => 1.5 Gbit/s, 150 MB/s
SATA revision 2.0 => 3 Gbit/s, 300 MB/s
SATA revision 3.0 => 6 Gbit/s, 600 MB/s

SATA revision 3.2 => 16 Gbit/s, 1969 MB/s 

 

1. dmesg 로그로 확인

# dmesg | grep -i sata | grep ‘link up’
[    2.569676] ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[    2.569697] ata3: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
[    2.569718] ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 300)

[    2.569746] ata2: SATA link up 6.0 Gbps (SStatus 133 SControl 300) 

 

2. smartctl 명령어

 :: smartctl 패키지가 없을경우 설치
# apt-get install smartmontools
# smartctl -a /dev/sdb | grep “^SATA”
SATA Version is:  SATA 3.1, 6.0 Gb/s (current: 6.0 Gb/s)
# smartctl -a /dev/sdc | grep “^SATA”
SATA Version is:  SATA 3.1, 6.0 Gb/s (current: 6.0 Gb/s)
# smartctl -a /dev/sdd | grep “^SATA”
SATA Version is:  SATA 3.1, 6.0 Gb/s (current: 3.0 Gb/s)
# smartctl -a /dev/sde | grep “^SATA”

SATA Version is:  SATA 3.1, 6.0 Gb/s (current: 3.0 Gb/s) 

 

3. hdparm 명령어 

# hdparm -I /dev/sdb | egrep “Model|speed|Transport”
Model Number:       ST3000DM001-1CH166                      
Transport:          Serial, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6, SATA Rev 3.0
  *Gen1 signaling speed (1.5Gb/s)
  *Gen2 signaling speed (3.0Gb/s)
  *Gen3 signaling speed (6.0Gb/s)
  *SMART Command Transport (SCT) feature set
# hdparm -I /dev/sdc | egrep “Model|speed|Transport”
Model Number:       ST3000DM001-1ER166                      
Transport:          Serial, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6, SATA Rev 3.0
  *Gen1 signaling speed (1.5Gb/s)
  *Gen2 signaling speed (3.0Gb/s)
  *Gen3 signaling speed (6.0Gb/s)
  *SMART Command Transport (SCT) feature set
# hdparm -I /dev/sdd | egrep “Model|speed|Transport”
Model Number:       ST3000DM001-1ER166                      
Transport:          Serial, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6, SATA Rev 3.0
  *Gen1 signaling speed (1.5Gb/s)
  *Gen2 signaling speed (3.0Gb/s)
  *Gen3 signaling speed (6.0Gb/s)
  *SMART Command Transport (SCT) feature set
# hdparm -I /dev/sde | egrep “Model|speed|Transport”
Model Number:       ST3000DM001-1CH166                      
Transport:          Serial, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6, SATA Rev 3.0
  *Gen1 signaling speed (1.5Gb/s)
  *Gen2 signaling speed (3.0Gb/s)
  *Gen3 signaling speed (6.0Gb/s)

  *SMART Command Transport (SCT) feature set
