All you eggs...

pretec-64.jpgYou probably know the saying: don't put all your eggs in one basket. Now, using Pretec's newest Compact Flash cards would be doing exactly that. These cards sport an amazing 64 and even 100 Gigabytes capacity. 100 gigabytes! That's equal to the hard disk capacity I have in the notebook computer I'm writing this on.

I wouldn't even be able to empty that card onto this computer, if it was filled. I'd run out of disk space long before having all images in safe harbor.

On the other hand it probably wouldn't be necessary to empty it right away, because filling the 64 Gb card would require me to shoot about 8,000 shots in RAW and the 100 Gb card would hold close to 13,000 RAW-images! And should I opt to shoot JPG in the lowest quality that my D200 offers, they would take up approximately 300 kilobytes per image, enabling me to shoot about 300,000 shots before I had to empty the card. Three hundred thousand! Most people don't shoot that many photos in a lifetime.

So even though I can only be astonished and fascinated by a 64 or 100 Gb card, I would personally stay away from it for now. I wouldn't like to have 13,000 images on one card. I personally aim at having one shoot on one card, and for that 4 and 8 Gb cards suit me fine. Of course that view may change when the DSLR's featuring HD video arrive, and you suddenly eat up memory card space at a much higher rate than has been the case until now.

That still doesn't change the fact that I would run out of hard disk space. But I can hardly blame that on the card. The age of terrabytes is truly here.

The size of a RAW file on a D200 is different from that of a D3, D700 and D2x, so it's quite conceivable that one gets less than 13,000 RAW images.

Bob,

There certainly is a difference between RAW-file sizes between cameras. That's why I write "it would require me..." and not "the card holds...".

The number will of course differ depending on your camera - and on the type of subject you shoot - some compress more easily than others. You can also turn on and off compression with significant difference in file size as a result.

The largest D200-NEF I have on my computer right now is almost 16MB, while the smallest is a bit more than 6.5, so there will be a big difference depending on subjects and settings. But with my average file size, I could squeeze in the numbers mentioned above.
