[外置硬碟] notebook 2.5" HDD 用電

剛拆了notebook 2.5" HDD,本來想買個外置case接usb用,睇中左一個平平地的外置case,但無供電制,請問係吾係所有2.5" HDD用usb唔洗另外供電?點知自已部pc或notebook 的usb夠唔夠力推HDD呢?
Thanks.

不用另外供電

    但係個sale話要睇我部pc或notebook 的usb夠唔夠力推HDD先決定係唔係要另加火牛,所以我先唔敢買住。

買隻有多1個usb供電頭嘅外置盒,唔夠電就插晒2個usb

I've no problem connecting a 2TB ext usb hdd to my nearly 5 yrs old lenovo notebook's usb 2.0 port !  And it would be even better if your nb has usb 3.0

睇你彩數吧,唔一定個個USB port都夠力推的!

買條USB Y-cable, 一個USB頭過資料, 另一個攞電

As long as the laptop concerned is connected to AC power, this should work well

BTW USB3 y-cable should be a must for every 2.5" USB3 HDD regardless of brandname generic or self-built type

Most 2.5" USB3 enclosures don't come with DC-in jack anymore, so connection with power adapter is impossible

As mentioned earlier, your only choice would be a USB Y-cable if you want you HDD to run under sufficient power

One more thing, do NOT go for the cheapskate HDD enclosures, you don't know what chipset is inside which may harm your HDD in the long run
A good enclosure costs around $110 and should come with modern chipset like ASM1153e
