[ LOS ] Measure IDE / SATA hard disk data transfer speed

如在 CentOS Linux 下做硬碟的 Benchmark 測試？使用內鍵工具 hdparm

# hdparm -t /dev/hda2 # 測試 IDE hda2 硬碟每秒讀取時間
/dev/hda2:
Timing cached reads: 1348 MB in 2.00 seconds = 673.60 MB/sec
Timing buffered disk reads: 168 MB in 3.02 seconds = 55.64 MB/sec

# for i in 1 2 3; do hdparm -t /dev/hda2; done # 連續測三次
/dev/hda2:
Timing buffered disk reads: 168 MB in 3.02 seconds = 55.68 MB/sec

/dev/hda2:
Timing buffered disk reads: 166 MB in 3.02 seconds = 55.00 MB/sec

/dev/hda2:
Timing buffered disk reads: 110 MB in 3.00 seconds = 36.62 MB/sec

參數說明：

-t : 實際硬碟讀取時間
-T : 硬碟快取讀取時間
/dev/sda : 硬碟名稱 sd 開頭為 SATA 硬碟 hd 開頭為一般 IDE 硬碟
