If a peripheral (external drive) is USB 3,
does the PC recognise the faster mode?

You would need a USB3 adapter (pci card or the like) to dapt your current Computer to use USB 3.0
They are backwards compatible.- see here for example click here#

There are two types of USB 3.0 adaptor cards card that can be bought right now to add USB 3.0 ports to a computer.

There are PCIe cards for desktops and ExpressCards for laptops or notebooks.

PCIe Cards

To install a PCIe card you will need to open up your computer and push the card into place. This operation scares some people but if you check out the procedure for installing a PCIe card (you could try a search of You Tube), you will see that it is pretty painless. Most USB 3.0 PCIe adapter cards have two USB ports and all will work equally well with USB 3.0 and USB 2.0.


Installing an ExpressCard is even easier. Just slip the card into the ExpressCard slot and you are ready to go. Usually, the card will be recognized instantly and you can go ahead and use the pair of USB 3.0 ports without rebooting.

Thanks, but what is an ExpressCard?

click here You would have to see if you have a spare PCIe slot in your PC (your graphics card will be using one) - simple to fit - just slots in. Another one here with 2 USB ports click here

See easy installation here - click here just click through the 8 pages.
Shouldn't take you more than 10-15mins.

I have been looking at USB3 for some months now - but - from the reviews I've been reading it's probably not worth it just yet.

Most of the reviews point to the write speed of your current platter based HDD's which is more than likely well below the theoretical speed of the USB3 standard. This is of course taking into account later USB3 equipped external HDD's and not the current USB2 ones.

As a result there are many posts of discontent around. I've even seen complaint posts where some other bottleneck has cut in when an external USB3 SSD has been connected.

I've yet to see a post where the statement actually notices much difference between 2 and 3.

KremmenUK - I agree with your comments. USB3 is new and I haven't really been reading many of the reviews simply because I have no plans at this moment in time to upgrade to it. I always prefer to wait to see how "new" things go before making any changes. However "geedad" is now more aware of what is needed should he wish to upgrade.

I have USB3 sockets on my new PC, what do I use them for? just treat them like USB2's
What equipment will benefit from using them?
