I researched 4 some time before I bought my cards. I needed a LOT of memory 4 weddings & portraits, but didn't have the equity 2 purchase the oft-spoken of Sandisk. I started researching.
These cards get high marks 4 speed, usability & reliability in Canon cameras, & in particular the 5D which is my main body.
No complaints..only praises! Do some research & you will find that these cards come highly rated 4 writing rates & low lag times. I am not shooting sports or in situations where I am having multi-burst imaging frequently, but if I were I would go up 2 the 120X without a hesitation. I have not had any lag time or writing problems, no accessing errors, no image concerns.
