More about versus hard drive faster
  1. via USB 2.0? External HDD and it will have easy access/ rewritable.
  2. Theoretically, an DVD that can write at 24x would write at about 33MB/s and rare are the external drives that reach 33MB/s so chanced are that the DVD would actually be faster. However, I would rather use an external HDD than a DVD, the medium will last longer, is less damage-prone and it is probably easier to have "incremental" backups on HDDs than DVDs.
  3. The OP didn't specify, but if his external is eSATA, then it is faster than a DVD drive.

    Good point, eSATA, USB 3 and even some NAS might be faster.

    Just a though, for 4GB you could probably use a simple USB key, will not be the fastest, but it's cheap and easy to carry (unfortunately also easy to loose or put in the washer/dryer).
  5. USB2 would be faster than writing to a DVD... The average write speed to a DVD is gonna be lower than USB2... I think.

    But like Zenthar said, "I would rather use an external HDD than a DVD, the medium will last longer, is less damage-prone and it is probably easier to have "incremental" backups on HDDs than DVDs."
