SDHC Memory Card Tests with my Canon XSi
August 20, 2008I ran some tests on the SDHC cards I’m currently using with my Canon XSi/450D
Based on Rob’s page, I’ll be looking for one of these cards for best performance: SanDisk Extreme III 8GB 30MB/s Edition
Update 8/29/08: PNY Optima Pro 8GB results posted. I ordered the PNY Optima Pro 8GB Class 6 card, and am disappointed in the results as it came in tied for last among my other cards. Perhaps the 2GB card Rob tested is better performing. I’ll have to try a SanDisk Extreme III 8GB next.
Update 9/16/08: AData Turbo 8GB Class 6 results posted. This has been the worst card of the bunch. It struggles to complete the 6 RAW shots and pulls off only 8-10 saves in the 10sec test period.
Update 9/23/08: SanDisk Extreme III 8GB Class 6 30MB/s Edition results posted. You can’t beat the SanDisk. It performed as its 4GB brother did – it wanted to get a 7th RAW burst frame, but just couldn’t make it. I’m definitely at the limits of the camera — a faster writing camera could take more advantage of the speed this card allows.
| SDHC Card | RAW Burst | Shots in 10sec |
|---|---|---|
| SanDisk Extreme III 8GB 30MB/s Edition |
6 | 16.5-17 |
SanDisk Extreme III 4GB Class 6 |
6 | 17 |
| SanDisk Ultra II 2GB Class 4 | 6 | 13 |
| PNY Optima Pro 8GB Class 6 | 6 | 12 |
| Patriot 4GB Class 6 | 6 | 12 |
| Patriot 8GB Class 6 | 6 | 12 |
| PNY Optima Pro 8GB Class 6 | 6 | 12 |
AData SDHC 8GB Class 6 |
5.5 | 9 |
Final Thoughts
Fry’s Feedback: The Patriot and AData cards are popular @ Fry’s because of their cost, but don’t provide the best performance.
Class Rankings: Don’t always tell the whole story as there’s wide variation in Class 6 speeds. A good Class 4 card is shown to outperform the cheap Class 6 cards.

[…] The XSi will take any size SDHC card. Sandisk Extreme III is a good card. The speed class (6 is the fastest) is supposed to indicate how fast you can write to the card, but this test found that some cheap class 6 cards were outperformed by better quality class 4s : https://codepoet5150.wordpress.com/2008/08/20/sdhc-memory-card-tests-with-my-canon-xsi/ […]
