thinking of getting an external hdd. im thinking of getting usb3.0 go flex or some other brands. the question is can i use that hdd to my usb2.0 cause my motherboard doesn't support it yet. hoping to upgrade my board within the next couple of months. is there any disadvantage or advantage , speed etc....
Well, if you're worried about speed, you might as well go eSATA. It's very fast, and many drives come with it. The only disadvantage is no hot swapping, so you'll have to reboot to attach a drive.
Ah ha! On the contrary my friend =) to get your PC to recognize your eSATA drive without booting, simply connect + power on the drive and put the PC to sleep, then turn it back on 10 seconds later and ta-da! your e-sata drive has been detected! saves plenty of time ^_^Y
If the cost is the same, then Yes.
I read a test recently where it was shown that using a usb3.0 drive in a usb2.0 port was quicker than a usb2.0 drive in the same port.
Plus you'll have a nice fast hard drive for when you eventually do get usb3.0 ports.
..When buying a seperate enclosure and a Hard drive to go into it, I look for both esata and USB3. For HDDs esata is slightly faster than USB3 even though spec is higher for USB3 (native vs translation).
.. Most of the newer compact BU HDDs do not sport both interfaces.
.. Usb3 will be more portable (ie going from a Desktop -> laptop)
.. For esata and desktop, would want a front panel estata - easiier to connect/disconnect.
.. esata requires seperate power I think, while USB3 provides more power (Current capability) than USB2 which ielimiates external power for a drive over 2.5 W.
As stated earlier, USB3 is backwards compatable with USB2 which also improves porability.
