USB 3.0 and external storage

Postby gate4exec » Sun Nov 25, 2012 5:56 pm

Is there any reason to buy a new 3.0 USB external hard drive when my mobo only supports 2.0 USB?

I think I have the following Asus mobo: P6T SE Intel X58/ICH10 Core i7 LGA1366 DDR3

Thanks!

If you want USB 3 get a cheap PCI-E add on card (get one with NEC chip)... USB3 is a lot quicker than USB 2.

the question becomes, is there significant difference to NOT get a USB3.0 drive? only if you gain significant money value should you not in my opinion. and with the prices where they are, there's not much room for significant price differences for the most part.

the usb3 external drive won't get any faster on an older usb2 port, but it'll be ready for any newer tech it may come in contact with. you'll be future proofing yourself if you buy a usb3 drive. then there's also cost to account for. the only reason to stick with older tech is it is VERY cost effective sometimes.

Thanks for the replies.

Will a PCI-E add on card improve performance beyond USB 2.0?

In other words, will I gain any transfer speed by using a PCI-E add on card or will I be capped at the USB 2.0 transfer speed regardless of adding a "add-on" card?

With each improved version of USB, the data speed has increased dramatically. The maximum speed is around 5 Gbps (Gigabits per second). Backwards compatibility must be retained with each advanced version, as to the controllers and hubs. But most devices may not be recognized on older USB controller or hub versions. Best to get an adapter card for the latest USB version, some have up to 10 ports. This WIKI link details the features and history of USB.

No, if you get a PCI-e add-on card, you will see a marked difference.. ON USB 2.0, I get about around 5~10Mbps.. On USB 3.0 I get around 40Mbps~70Mbps.. I backed up my NAS drive through a PC, the NAS drive runs on Gigabit LAN, using a USB3.0 drive and the speed averaged around 28Mbps which was pretty good.. Took 3.5 hours to do around 400Gb of data - The Gigabit network was the bottle neck, but it still did it.. Also used a program (free) called terracopy, it doesn't stop if there is a file issue like the M$ one does...

Is their a free utility to measure ones transfer speed?

Also, can anyone recommend an "Add-on" card that will take advantage of the faster transfer speed?

This one seems reasonably priced and has decent feedback on over 100 reviews:

One last newbie question, what are some other common uses for this Add-on card (other than doing external storage transfers)?
