What SD card has the best reliability?

<p>i have 2 of these wintec 8gb class 10 cards and they have performed flawlessly in my canon 60d....from 90+ this past summer to 10 degrees this morning</p>

<p>Quick note about high capacity cards, Steven. </p>

<p>Your computer might have trouble reading cards with capacities 4GB or higher if it's is older than 2007. Should this happen, the symptoms is that the card reader just hangs until you remove the card. </p>

<p>If you should have an old card reader, you can try finding a firmware update from the computer manufacturer or simply buy a new one. </p>

<p>Thanks for the heads up Michael. Luckily I have a newer iMac with a built in SD card reader which supports SD cards up to 2TB. But I will remember you advice if I encounter a situation where I need to use an older computer. </p>

You said no video, but if you decide to shoot RAW, high data rate is helpful. The Sandisk Extreme 8GB rated 30 MB/second is only $15 now, and you can step up to 45 MB/sec for $30. At more than twice the price, 16GB SDHC cards are not yet cost effective. Other brands are fine. I have an Adata class 10 that has had no problems in adverse conditions. Class 10 supposedly means 10 MB/sec or higher.

<p>Most of the time everything works seamlessly these days, but going with a Class 10 card automatically isn't necessarily the best choice. Some devices, including cameras can exhibit timing issues with anything above a class 4 card. Try to determine what the device manufacturer recommends before buying if possible. <br>

Cameras that do video usually will work well with the faster or fastest cards but testing will reveal any weaknesses though determining the cause of problems can be difficult.</p>

<p>Don, can you elaborate on the timing issue? </p>

<p>I would have thought that, in general, typical bottlenecks occur in the camera's buffer (size) and faster writing cards will clear the buffer quicker. </p>

<p><br />This makes no sense at all. The problem comes when a card is receiving more data than it can handle, not less. The speed of a card is the <em>maximum</em> rate at which it can receive data.</p>
