    New CF card or .....

    Here's the thing, I just succumbed to temptation and bought an A900.
    I go off for a short break (I know, I know, yet another) in the Moselle valley in a couple of weeks so what to do about flash memory?
    I have two 8GB Sandisk Extreme IV (45MB/sec) cards and an older 4MB Ultra II (15 MB/sec).
    On the A700 that's a 1000 RAW images but only 500 with the A900.
    16GB Sandisks run out at over 100 apiece from a reputable supplier, granted they are 60MB/sec devices but I don't need that.

    The solution, a 160, "Nexto" 320GB portable backup device.
    Basically it's a Battery powered, 320GB, 2" SATA hard drive and in size is, unsurprisingly, similar to a standard 2" ext. drive but about twice as thick.

    The NexTo LiPol battery does 60GB between recharges and if thats not enough (it is for me) you can buy an external battery which is good for another 80GB. Charging is done via USB or a provided mains PSU.

    It connects to the computer through either SATA (best 60MB/sec) or USB cables.
    It takes CF cards or a whole bunch of Memory stick/SD variants via a second 4in1 slot or via USB.
    The device contains a microprocessor and eeprom software which allows for several functions but I'm only concerned with one (for now).
    That is, automatic transfer of images from the CF card with data verification.
    This function is selectable via a simple Menu System on the front LCD.

    In use, nothing could be more simple, plug in the CF card and the NexTo recognises the card, creates a new folder, copyies all the images from the CF card, compares the copies with the originals (veryfying) and then deletes the CF card ready for it to go back in camera. The whole process takes less than six minutes for my 8GB Sandisk. A different folder name is generated every time you put in a CF (or other) card.

    When you get home just plug the NexTo in with the provided SATA cable (or USB cable) and shift them to your hard drive. Here's a screen shot of Windows File Manager showing the NexTo plugged into the computer and showing two 8GB transfers from CF.

    Don't you have a MS slot in the camera as well?
    On my a700 I always have a 8GB MS and 8GB CF.
    But I agree....get more cards.

    I have 2x 8GB cards but that gets me 400 images and nowhere near enough for a weeks shooting.

    The crashed HDD is a valid point but if I were a Pro, I'd have two backups. Of course, if I were a Rich Pro I may not worry about the cost of the CF cards.

    Lightbulb Speed indeed ...

    After my initial experiences with the α850 ... you need a CF card that can write rather fast. I think SONYNUT (Steve) will confirm this finding. I know many others who did the upgrade can attest to this issue.

    The α700 is very forgiving in that regard ... and 133x speed cards are just dandy, but they will not perform correctly in the α900/α850 camera. Just don't do it.

    Purchase a new 32GB 420X UDMA 6 card and be happy. It will provide plenty of room for your images and the speed issues become a thing of the past. There is just a mandatory write-speed you have to comply with, or the CF will fail in the camera. Don't believe it ... you will.

    And yes, of course, there is a cRAW Mode and a cRAW + JPEG.

    Remember: It is usually the GLASS, not the camera (except for moving to Full Frame), that gives you the most improvement in your photography.

    Don, my 2x 8GB Sandisks are Extreme IV which write at 45MB/sec; this is more than the A900 can handle so speed is not an issue.
    The 32GB CF Cards you mention cost 190 each and I would get 666 (RAW+JPEG) or 846 RAW only images. Again this is insufficient for a week's (well actually 10 days) shooting.
    Two cards would do the job, but at 380 I had second thoughts.

    I purchased and use the San Disk 16 GB Extreme III CF Card (SDCFX3-016G-A31) with my A900 and have been very happy with it. Although a number of friends have recommended getting several 4GB cards instead of the larger cards. They prefer the 4GB cards because they are usually cheaper and are easier to dump directly onto a DVD.

    With the A900, if you have both CF and memory stick cards, you could always load both in and switch when one gets full.
