    After Thanksgiving I got some deals on SD cards from Buy.com and Circuit City.

    I got the Sandisk Ultra II 1GB and a Sandisk "regular" 512MB SD cards. I use these SD cards to save my working files on my PC. I don't use them directly with the Treo 600 I carry. It appears that the regular card is much faster than the Ultra II by 4 seconds in saving my 3MB Excel file. I also ran the VFSMark test, and the final score is better on the regular card!

    VFS Card Speed - OK VFS Card Speed - Good

    Just to see if Ultra II card was a lemon, I bought another one from Costco....and it was even slower!

    I was really hoping for a significant increase in speed.

    Does Ultra II really make a difference in speed for you or is it just marketing hype?

    Run VFS Mark Test like chungmike did, to see if it really is.

    I used realtime instead. To transfer Tom Tom 4.1 Maps onto the Toshiba card via hotsync, approx 3 hours, Ultra 11 was about 20 mins. the Toshiba card was so slow I have given up using it. I couldn't use voice recorder on my T3 as it was just cutting in & out. It's filed away somewhere in a safe place. Now where is that safe place?!

    Here are a few of my notes on SD cards. I was unaware of all the
    memory speeds available. Believe me a 133X will really make your
    Camera/PDA seem fast and well worth a few extra $ up front.

    The higher the speed rating, the faster your Camera or PDA will be able to write information to the memory card.

    1X = 150 KB/sec
    60X = 9MB/sec
    66X = 10MB/sec
    133X = 20MB/sec
    150X = 22MB/sec

    SD cards range in size from 16MB up to 2GB. As with other flash media,
    SD cards come in different transfer speed ratings. Most SD cards not
    marked "High Speed" or "Ultra High Speed" are probably only ~2Mb/s
    capable. The latest cards are capable of transferring data at 8-10Mb/s
    such as the ATP 60x, SanDisk Ultra III or Extreme cards. Transfer
    speed is an important factor if you record high framerate motion video
    or high quality audio tracks. Many digital camera makers only certify
    their 30fps VGA motion video capability when using "high speed" SD
    cards.

    Capacities: 64MB, 128MB, 256MB, 512MB, 1GB and 2GB

    SanDisk Extreme is 60X = 9MB/sec
    SanDisk Extreme III is 133X = 20MB/sec
    SanDisk UltraŽ II is 60X = 9MB/sec (plus adds USB)
