Q: What speeds can one expect with the new USB 3.0 PCI card? What is the limiting factor in the speed?

    First off, if you aren’t using any devices that actually support USB 3.0 you aren’t going to notice any kind of a difference.

    Second, I’m pretty sure they’re only making PCI-Express cards for this since old PCI can’t support the full bandwith of USB 3.0

    Assuming you get a 3.0 card, and some kind of device that supports USB 3.0, your speeds are going to be dependent on the device itself.

    Even with your standard USB 2.0 flash drive, you’ll find that the performance speeds of these sticks vary widely from one brand to the next.

    So if there is something you’re interesting in buying that supports USB 3.0 I suggest you find some reviews and performance benchmarks on the device first to see how it will perform.

    Thanks for the reply.
    i am thinking about using an external hard drive to back up my pics and video. I have a lot of video. There are External HD’s out there with the newer 3g/s spec and one of them I found even comes with the USB 3.0 card. I did some research and it seems that atleast the ASUS card needs 4X PCI-E minimum to prevent bottleneck as the 1X PCI -E would cause under some conditions. This means Id have to give up my 16X PCI-E slot. No problem. Maybe there is a quicker way to save to backup all together. Im open for suggestions.

    Thanks, Ken

    The Western Digital MyBook 3.0 1TB or 2TB models are supposed to be pretty fast. See http://www.crunchgear.com/2010/02/01/review-western-digital-my-book-3-0/

    Generally for backups the focus is on space instead of speed. Though if you want your drive backups to go as fast as possible because you won’t be automating them overnight, this might be a good way to go.

    Just remember that moving your files to this (and not just making a copy) doesn’t count as a backup, this drive can break too. If anything it is more susceptible to breaking since it can fall off your desk.

    So just have a good backup strategy in place with whatever you do.

    I would be copying to my 2 machines not moving files only. I get what you say about the drive being delicate. I’m open to suggestions as I have not bought any hardware for this back up project.

    If you’re looking for unified central storage for your home network, you might like something like a NAS (Network Addressed Storage) or for some more features a box running Windows Home Server: http://www.microsoft.com/windows/products/winfamily/windowshomeserver/default.mspx

    I currently use a windows home server to handle my automatic pc backups and to use as a shared storage area between computers. I have two harddrives in it that allows all data to be mirrored on both drives, so if one fails no data is lost.

    I still have the risk of the house burning down, so if you really want to safeguard your data even more you might want to use something like Mozy or some other on-line backup solution. The mozy software will also let you target your own local or remote backup device.

    Anyway, all food for thought. 🙂

    Thx again Mark
    One machine at work and the other at home. I like the mirroring dual HD idea. My internet connection is super slow and any attempt to upgrade would be expensive as we are in a pocket between towns and would have to pay to run over 1.5 miles of cable. How reliable are solid state external HD’s?

    Just as reliable as any other storage tech, though much more expensive per megabyte.

    If you want speed and storage space the Western Digital MyBook would probably be your best choice. See the reviews posted above for benchmarks.
