The PE4H by HWTOOLS |

There are several significant drawbacks to this device as well (being that it's still extremely new). The first is the fact that not every laptop has an ExpressCard slot and using an add-on adapter to install one is not recommended either due to severe performance reductions. Another lesser catch is the necessity for running it with Windows 7 for maximum driver support. Third is the fact that, although these graphics cards have their own onboard memory, this external device requires this memory to work in conjunction with the laptop's memory (so if you have a 1GB graphics card, it will instantly take away 1GB of your laptop's memory). Finally, some laptops with the ExpressCard slot still won't work with this device for a number of known and unknown reasons.
Besides all of these complications of the experimental device, some users will certainly benefit from the greater flexibility of beefing up their graphical horsepower whenever needed. If these devices are improved over time, they can certainly expand the desktop graphics card industry into the portable computing market as well. All we need now is an external enclosure for these cards to make them safer to transport with their laptops.
