Though USB3.0 has just been putted into use for less than 2 years, but the super speed of USB3.0 determines it will be the main transmission interface in the future years. But it seems a little pity that, for most laptops before 2011 even now came with no USB3.0  interface and just came with USB2.0. Today, I will teach you how to make up this pity of Toshiba pa3465u-1brs battery laptop.

Fist let's learn more about USB3.0 and to know that why the USB3.0 is important. USB3.0 standard released by the end of 2008, its theoretical maximum transmission speed of 5Gb / s. Before 2011 only a few high-end notebook will also configure USB3.0, USB3.0 most recently beginning to spread rapidly, many mainstream notebook prices also are equipped with this interface. Compare to USB3.0, the max speed of USB2.0 is only 60MB/s. It seems so slow when we meet large files.

But do you note that there is a "waste" interface on your laptop? It's the Express Card interface, the max speed of Express Card interface is 4GB/s and this speed is a little lower than the USB3.0, but it's also very faster than the speed of USB2.0. And do you have ever used this Express Card interface? For me, I have never used this Express Card interface of my Lenovo IdeaPad Y460 and I mistake it for the SD card reader at first, and the SD card almost can't be pull out from it.

Now, maybe you have know the idea about how to let your laptop support USB3.0. ExpressCard technology is the Association by PCMCIA in spring of 2003 announced a new technical standards, the use of this technology more on a laptop, used to provide thinner, faster, and lighter expansion module. It is a hot-swappable USB as serial data transfer interface. Usually produced before 2011, many laptops are configured this interfaces such as Lenovo Y460 battery laptop.

ExpressCard interface is divided into two specifications, one is the width of 34mm of ExpressCard/34, the other is the width of 54mm of ExpressCard/54, their lengths are 75mm, thickness is 5mm. 34mm module compatible with the slot in 54mm size which, otherwise not. ExpressCard maximum theoretical transfer rate of 4Gb / s, this rate can be considered at the time, it's the pole "speed".

We convert this equipment to achieve this ExpressCard expansion card is, in fact, it is not a new product, the device has appeared several years ago. We selected the ExpressCard/34 expansion card for the 34mm standard, and uses a "headless" design, which means that this card is plugged into your notebook's ExpressCard plug in will be completely "hidden", the card itself does not exposed outside the body,
