What kind of card reader are you using?@Mercurial, before you buy that Extreme IV card, have a look at this. I decided to get one 4GB Sandisk Extreme III card to benchmark (since I have a II and a IV already) before I stock up for my trip, and the results were interesting. I also decided to look up the price (amazon.co.uk) and add it as a cost per performance figure:
...
At a mere 3.33 MB/s difference (20% odd) for roughly double the money, the Sandisk Extreme III looks like the best bang for buck by far. I'm off to order three more![]()
How many images do you import each week that speed is so important?SanDisk Extreme® 2.0 USB Readers. I was thinking of replacing it with a SanDisk Extreme® FireWire Readers but the price difference is substantial. And my camera appears to be slower than my reader...

Do you know of an app for testing cf cards?
I'm not looking for benchmarking (the initial transfer is hardly the slowest link in my chain) but something that might indicate the 'health' of the card - anything that might be a precursor to a card failure.Nope. I just copy 4/8GB worth of CFR2 files to it, stick it in the camera, format it, wash/rinse/repeat...
Not really sure that would be a great idea. Steve Gibson - creator of spinrite - was asked if his application could be used on flash memory and he said the intensity of the read/write would quickly destroy it.Well, my cycle should - it write faster to the card than my camera does (from what I can tell), and for longer periods of time on end. And with a bit of shell scripting I can make it happen automatically in the background. I can even intensify it - copy, sync, checksum, delete, sync, repeat repeat repeat...

Why - is it going to be of any use to you? IIRC the 450D takes SD cards and those results are mostly for CF cards.Thanks so much for this![]()

I'm pretty sure the 40D takes CF - he also has a sony point and shoot hence the Sony Memorystick.I thought this was for SD![]()

I could be mistaken though.
so . . . got a camera yet?Yeah. I just assumed that since he addressed me in the post that it was for SD. Indeed, the 40D does take CF.
