如果以7200rpm 3.5" 來說
他們的大約速度是多少
作者: a_guy 時間: 2008-10-17 15:26
eSATA 3Gbits: up to 3Gbits/s (300MB/s)
FireWire 800: up to 800Mbits/s (100MB/s)
FireWire 400: up to 400Mbits/s (50MB/s)
Hi-Speed USB 2.0: up to 480Mbits/s (60MB/s)

應該個 limitation唔響個5400rpm or 7200rpm 度

實際呢

eSATA is fastest. Almost same speed as internal SATA.

可以參考下以下呢幅來自Free agent pro 750G評側的圖

除左 brust speed 外
其他分別唔大
但貴成二三百度
其實 firewire 是否比 USB stable 好多

Free Agent Pro 個 eSATA 係廢的, 唔作得準, 以我個人經驗, 用 eSATA 大約有 7xMB/s (WD MyBook Home Edition)

FIREWIRE 比USB快而且用少D 資源

firewire 同 usb 既 speed 其實差不多, 不過通常 usb 的 device 多, 會 interrupt 個 transfer.

what is the different on speed in your mybook
作者: chpyeung 時間: 2008-10-21 14:47
usb 同 1394 都係大約 2x-3x MB/s, ESATA 大約 6x-7x MB/s, 單一大 file 計 (over 1GB per file)

以前有個USB/1394兩用嘅2.5"HD Box,用1394係快過同stable過用USB嘅.(無Check過速度,但好明顯感覺到)

Just copied 161GB of TV recordings from my WD MyBook 1TB to PC (seagate 1.5TB), the speed is around 80MB/sec.

Should be, but practically may not because the controller chip in the external HDD box may slow down the speed a bit. Furthermore, the HDD model used in external HDD box most likely has less performance but better energy efficiency than internal ones.

Of course
Self IO chip is required for IEEE 1394 connection
