I've been using 95mbs with no issues, but I would advise you to try what you have and depending on your habits, they will likely be fine. I get the impression that some folks like to see how long it takes to load the buffer and it must be important for them. After many thousands of bird shots, I have yet to load the buffer, but that's me. I do have some faster cards and it makes no difference to me. Try what you've got!
Right. Makes no difference ... becuz:
When doing a burst you’re not writing to the card, only to the buffer. Most current cameras have fairy large buffers so they absorb the whole burst and then write to the card after the fact.
If you have a roomy buffer but your camera forces you to noticeably wait between bursts ... especially the longer bursts ... then THAT is when you need a faster writing speed for your card.
Usually the card’s readout speed is boldly on the front of the package but the writing speed is buried in small print gobbledegook on the back :-(
