方法二
sudo smartctl -a /dev/sda | grep SATA
输出
SATA Version is: SATA 2.6, 3.0 Gb/s
方法三
sudo hdparm -I /dev/sda | egrep "Model|speed|Transport"
输出
Model Number: Ubuntu14.04-0
Transport: Serial
* Gen1 signaling speed (1.5Gb/s)
* Gen2 signaling speed (3.0Gb/s)
备考
- SATA I (版本 1.x) 接口, 正式名稱爲SATA 1.5Gb/s, 是第一代SATA接口,運行速度爲1.5Gb/s。這個接口支持高達150MB/s帶寬吞吐量。
- SATA II (版本2.x) 接口, 正式名稱爲SATA 3Gb/s,是第二代SATA接口,運行速度爲3.0 Gb/s。這個接口支持高達300MB/s帶寬吞吐量。
- SATA III (版本3.x) 接口,正式名稱爲SATA 6Gb/s, 是第三代SATA接口,運行速度爲6.0Gb/s。這個接口支持高達600MB/s帶寬吞吐量。向後兼容SATA 3 Gb/s接口。
SATA II規格向後提供向後兼容SATA I接口的功能。SATA III規格提供向後兼容SATA I和SATA II接口的功能。但是,由于接口的較低的速度限制,驅動器的最大速度將會降低。
