Best SD card, SDHC or SDXC card for Canon T3i or 600D
SD card speed classifications:
The speed ratings are very confusing for consumers. The speed Class Rating are the official standard defined by SD associated. The speed is defined as the minimum transfer speed
- Class 4: 32 Mbit/s (4 MByte/s), 26x
- Class 6: 48 Mbit/s (6 MByte/s), 40x
- Class 10: 80 Mbit/s (10 MByte/s), 66x
Which brand of SD cards to get and how much memory do you need?
Considering the value, reliability and speed, the best cards to use with Canon T3i or EOS 600D are SanDisk Extreme III SDHC cards and SanDisk Ultra SDHC cards. Lexar professional 133x SDHC card is another very good choice. SanDisk Ultra SDHC card is fast enough (15MB per second data transfer), reliable and not very expensive. I prefer to have a couple of 8G San Disk Ultra cards instead of 16G.
