Hi, is it necessary to use an ultra fastĀ* or hi speed sd card and card reader? And if not necessary is it recommended and what could it affect? Is it just in the case of the card reader that it would take longer to load onto the computer, or is it that information would be compromised?Thanks!

No, it's not necessary to use a fast card or reader. With some models, a higher performance card may be needed for optimum results.

For example, movie recording length can be impacted using slower cards with some cameras. The number of photos you can take in a row before a pause can be impacted by card speed with some cameras.

But, with many models (probably most non-DSLR models), you won't see any difference in performance between a slow and fast card (because the bottleneck is the camera's interface speed to the card, versus the card itself).

A fast card can help transfer photos faster. But, you really have to take them on a case by case basis. Also, it's not uncommon for a "standard" card to be just as fast as a "high speed" card. They may be coming off the same assembly line with different labels on them. ;-)

You may see both slower and faster cards, even though they are the same brand/model, too (different card batches using different components, depending on when they were made).

When buying a card for a camera, I'd see if the manufacturer has any kind of compability chart. I'd also check with users of the same model and find out what they're using, and how well it performs. A card that's fast in one camera, may be slow in another (due to differences in the way given model "talks" to a card).
