Fast, but external power may be troublesome.

I got this card to connect my external HDD to my older USB 1.0 laptop. So far, the card is working just fine, and transfers files just as fast as my new laptop which has USB 2.0 as original equipment.

However, there is a caveat.... if any of your peripherals require USB power, like thumb drives, mice, etc. there is a special cable that must be used. It's a pass though USB plug that has a cable coming off of it that powers the USB 2.0 PCMCIA card. This way, a USB 1.0 port provides power to the 2.0 card's ports. I had a little bit of difficulty with it because of the way my laptops USB ports are arranged (HP Pavilion ZE5185). If I used the laptop's side port the power plug's cable points down and is too tall for the laptop's thickness, and if I use the rear USB ports the cable is right up against the laptop's power cord. It's able to fit there, but it has some pressure on it.

For what it's worth, the supplied USB power plug is setup so if you look at your computer's USB port and the "tongue" with the contacts on it is at the bottom, the adapter's power cord will come out on the right side.

The manual also notes that if your USB device requires a lot of power like a floppy drive, high speed USB powered hard drive, etc. the supplied cable doesn't provide enough juice and you'll need to purchace some special AC adapter.

I don't know if all the USB PCMCIA cards have this problem, this is the only one I have ever used.

Anyhow, it doesn't much matter to me because my external HDD has it's own power supply and works fine without the USB bus being powered. My card is working great, and now I can speedily transfer files. What takes an hour with USB 1.0 takes only a few minutes with the 2.0, well worth it. And I purchased this card for much less than the other's I've seen.
