    Thanks for your recommendation of resellers and for reminding me of the importance of the extended warranty. I wasn't planning on spending the extra money but it's a wise decision.

    You're welcome.

    While the external drive may cost the same, drive storage sizes has increased.

    External drives come in Terrabyte sizes instead of Gigabytes.

    The most common sizes are 1,2 and 3 TB size drives.

    There are larger Terrabyte size drives, but are more expensive.

    If your iMac is a late 2006, 24 inch screen model, with a 2.16 or 2.33 Ghz CPU, these iMac models had one FireWire 800 port.

    Purchasing an external FireWire 400/800 hard drive using the FW800 connection, the speed of data transfer to and from the computer is nearly identical to running from the iMac's internal hard drive

    It seems that is a viable option then. So, I should look for atleast a 1TB drive with FW800 connection. Does it need to be a SATA drive?

  • MichelPM Level 6 (11,435 points)

    If your iMac is a 24 inch screen model and has the FW800 port, then yes, this is an alternative.

    No. The drive doesn't have to be a SATA drive.

    Here's the external drives I use with my 2009 iMac.

    I have two of these. One is a 2 TB drive. The other is the 3 TB

    I have these connected through FW 800 connections to my iMac.

    Thanks for that.

    Mine is actually the 20-inch version which has only two FW400 ports. Do you think that is an adequate connection speed to run from an external drive?

  • rkaufmann87 Level 9 (55,303 points)

    FW400 is very fast, much more so than the USB ports your computer has.

  • MichelPM Level 6 (11,435 points)

    FW400 is much faster than USB 2.0.  FireWire 400  will still be slower than your iMac's internal drive, though, for running OS X off of on a daily basis.

    That's why I was hoping you had the later model 2006 iMac with FW800 ports.

    FW800 will have throughput that is nearly identical to running OS X off of the internal drive.

    You wouldn't really notice any type of lag or delay.

    WIth FW400, they will be some slow down. The only way to test this is to buy a drive, plug it in, format the drive and install the OS to see how much of a delay there is and whether or not you can tolerate it.

  • Dr. Benway Level 1 (0 points)

    Thanks again. Do you think there would be any difference in performance between a portable drive and one that needs to be plugged in for this purpose?

  • MichelPM Level 6 (11,435 points)

    If you are referring to something like a wireless WiFi or Bluetooth drive? WiFi drive speeds are based on the speed of your router WiFi connection. So, maybe fast, maybe slower. Same with Bluetooth drives.

    And you run the risk of loosing connection with the drive and crashing your system.

    A Direct connected drive is a much better solution for everyday use.

    FW400 may work for you, but you would need to purchase a drive and try it. Make sure it's a FW drive that has its own power supply and is not powered from the FW connector,,itself.

    Self-powered drives have better throughput speeds than ones that are powered from the connector also called Bus-powered.

    Got it. Thanks again.

    You're Welcome!

     

    Good Luck!

    I'm curious to know why you don't recommend using an external disk with greater than 750 GB capacity to boot an Imac from. I have borrowed a 3 TB external drive from a co-worker in order to try running my Imac from it before I invest in a new drive myself. There is about 750 GB of free space on the drive. Can I install the OS without formatting the drive first?
