[citation][nom]invlem[/nom]Well Yes and No... It really depends on your application, eSata may be faster, but USB is still more usable/universal. If you're planning on using the drive for back up purposes eSata and know all the devices you are going to use it with support eSata, then it is probably the better solution. If you want it for mobility purposes, transferring files to various destinations, USB is more reliable. First these usb3 drives are self powered, meaning no AC adapters to worry about, the PC provides the power, also since its backwards compatible with usb2.0 100% of the devices you want to plug into will work, eSata is great but its not nearly as widely adopted as usb... I'd rather transfer my files slowly at usb2.0 speeds to my destination system, than not at all due to a lack of eSata ports.[/citation]
from what i understand.
a usb3 case that takes full advantage of the harddive is hard to find, much less cheap
how ever a esata case can be found for under 30$
so really it comes to how you are going to use the hdd...
personally i want to take all moving parts out of my computer besides fans, so i could go with esata and be happy, but if you want more or less a guarentee that you will be able to hood that drive up to almost anything you can think of, even a bad usb3 case would be better.
