    DVD drive

    Hi,

    I have two questions.

    (1) I am planning to buy a new DVD drive. The driveI was looking at was a USB 3. My computer uses a USB 2. Will the drive be compatible with my laptop?

    (2) Can the DVD drive be plugged into a USB 2 hub?

    Thank you.

    1) USB 3 is backwards compatible with USB 2 so, yes, the new USB 3 DVD drive should be compatible with your laptop (provided you're not running a very old OS like Windows 98).

    2) Yes, it can be plugged into a USB 2 hub but, if it doesn't have a mains power supply, it's likely to need 2 USB sockets - 1 for power and data, the other for additional power.

    Hope this helps...

    Gladly, you can do all those. However, your drive cannot utilize the full USB 3.0 speed. Its speed will be capped. Also, try getting a powered hub if your drive features no power cord. This can help reduce the power draw on the mobo.

    Is the new drive an External or an Internal or an Internal in an External case? The internal doesn't use USB but the SATA or PATA drives connect to the motherboard. The Internal type drive in an External case could use either USB 2 or USB 3 depending upon the case itself and the ports on the computer.

    yes and yes. As for the speed issue brought up with a USB2 port it is non-existent with an optical drive (ODD) because the transfer rate is so slow (figure 50Mbps tops) that USB2 (480Mbps theoretical; in reality much less, but not that much less) can readily keep up.

    I assume an optical drive cannot be powered off of a USB port? It would be nice if I were wrong, but ODDs are usually pretty power hungry especially on burns.

    I have 2 External USB Optical drives, one a Lite-on and the other an HP, both require a Y-cable for 2 USB ports, one leg for data and power and the other for additional power, doing so eliminates the need for an external power supply. These drives are quite handy for Netbooks and some of the lightweight Notebooks that do not include an internal ODD, also come in handy when having an internal drive that doesn't get recognized or work.
