    I just found a WD MyBook 500 GB external harddrive with
    an eSATA connection. I was wondering if i could hook that up
    to my MacBook Pro 15" ??
    it's much faster than firewire 800!

    can you buy an express card to eSATA adaptor ?? that would be awesome if you could...

    There are several eSATA to ExpressCard/34 adapters out there. I have the one made by FirmTek and love it. I use it with their own dual-bay enclosure. They have given me great customer service as well. Addonics and a few others have versions out.

    I wouldn't think it would be much different than firewire 800.

    The theoretical cap on eSATA is several times higher than that of Firewire 800. The actual speed difference isn't that amazing. The reason for this is you hit the maxiumum speed that the drive can read/write data way before you hit the maxiumum thoroughput of eSATA. Where eSATA will REALLY shine is in a raid setup where multiple drives are working in conjuncion to multiply read/write times. eSATA could keep up with that.

    Cheers :)

    esata is just that external SATA. For example on the mac pros you can actually buy just a face plate that goes in a pci-e slot that you connect to the 2 extra internal connectors and it gives you 2 esata ports on the back.
