In photography write speeds are the most important, as this is the speed at which a device such as a digital camera can write photos to the memory card, if this is slow, then it may slow down your shot to shot time or the amount of photos you can continuously write to the card. The read speed is important for when you want to view the photos or copy them onto a computer or other device.

Another important factor to consider is warranty and reliability, ideally you would want the most reliable card possible so that your photos are never lost, however, if the card does fail then a long warranty will mean that the manufacturer should replace or repair your card. Although recovery of images is unlikely (and another subject).

Reliability can't be determined on new cards, as it could take a long time for the card to fail, if it ever does... one thing to consider is how durable the card is, and if you look at Samsung Plus/Extreme cards, then they are waterproof, shockproof, magnetic proof and come with a 10 year warranty so should survive much more mis-treatment than others, as we found out in our test of one of their microSD cards.

* We've included XD memory just as a reference point, and you can see why it was a good idea for manufacturers to move away from using XD. Updated: 27/01/12.

Some the cards in this test are advertised for very high speeds, where as in practice they seem to be capable only a third of that. I would like to see a similar review of high speed CF cards.
