eSATA Adapter?

I have a 4th generation (mid-2008) model MacBook Pro. I've been looking at a Western Digital external hard drive and it's saying one of the input options is eSATA which is about 3Gb/s in comparison to USB 2.0 at 480 Mb/s.

What I was curious about is if there was a way to get either an adapter or just a normal way to connect an eSATA input into this MacBook Pro. I have the mid-end MBP of the mid-2008 (15 inch screen, 2.5Ghz processor) model.

Any help would be greatly appreciated.

An adapter is inexpensive enough: Link but I'm not sure that's going to result in eSATA speeds. You need to do some research on that.

Regards.

Thank you, although that's not quite what I was looking for. What I need is possibly something that will go from eSATA into a either USB or Firewire. I highly doubt it for Firewire or USB, because their speeds aren't up to 500 Mb/s.

I want to directly connect the External HD to my MBP to get the full transfer speed of eSATA. It's fine if I can't, but this isn't something I've never dealt with before.

You'll need an express 34 card which will give you esata port with full 3gbps speed on your macbook pro.

umang has it - here are a few at Amazon so you know what you're looking for
