    I searched and couldnt find the exact answer, so i'll ask you guys..

    Whats the best external HDD for TM?

    How big should it be for this purpose?

    Specifically, i would love to buy one that doesnt require an external power source, because i will be using it with the laptop, on the road, a lot.

    Which is better for this? FW800 or USB?

    Whats the disadvantages of not having an external power source? Slower read/write speeds..etc?

    Thanks everyone! Love the community!

    I like Western Digital fire wire but I suggest any major brand that's on sale in your budget.

    At least as big as your internal but I like to use at least double the size. The external drive can be partitioned for multiple uses and your storage/backup needs often change so a large drive can accomodate and grow as your needs change.

    Now you are talking about a usb powered HD and you will be somewhat limited in your search for one but they can still be obtained.

    Firewire is a streaming connection that has an advantage that makes it somewhat faster. Todays USB connections have improved (2.0) but it sends information in packets which slows down the communication.

    The external-powered drives have more power to operate. If the drive needs more power than what can be obtained though your usb port, it must be plugged in to a power source. Some are usb powered only, some are external power source only and some are either or depending on the enclosure.

    Me too! :)

    WD Mybook 2.0 TB

    After the beginning of the year, I am getting a mybook 2.0 TB and I will run it in RAID 1 mode (1.0 TB mirrored)

    It has firewire and USB 2.0 interfaces.

    I have THIS and I love it. It is USB 2.0, needs no power adapter and is VERY small. It uses a 5400 RPM 2.5" Laptop hard drive which is why it can be so small. It is not much bigger than an iPhone... has worked VERY well for me.

    I have a LaCie USB2.0 7200RPM 500GB US$120... it works well, gets a little noisy when transferring large files tho. Otherwise it's a great value HD.
