Bests & Worsts Reviews from Amazon

This is in response to the first reviewer's valid observation/comment, notably that "This card seems to have a good transfer rate when copying a small number of large files. However, it still crawls when compared to my panasonic 256MB SD card that is much older when copying a large number of small files." The reason for this is that the bigger the card, the longer the recycling time between shots or uploading or downloading files. The best explanation I heard is that info processing in memory cards is similar to it running around a track - the bigger the card, the longer it takes to get around the track. That's why I ALWYAS recommend people who insist on having 1 Gig memory to buy TWO separate 512 MB cards! Also, in the slim chance your card gets corrupted, you won't lose ALL of your precious photos. Btw, I have owned the ULTRA II versions of their Compact Flash Card, Secure Digital Card, and Memory Stick and have never had any problems. But it's always advisable to be "safe than sorry". Finally, unless it's an older camera, your camera will most likely benefit from the increased speed these cards allow. Therefore, I wholeheartedly believe they are worth the extra cost. I do NOT recommend the regular Sandisk cards however - they are Overpriced and SLOW.
