Hello all,
No matter how I search, I'm still feeling uncertain of the information I've found and like to ask if anyone could point out any mistakes in my understanding of this.
Basically, SD Speed Class is the guarantee of minimum speed (i.e. Class 2 = 2MB/s).
However, Cards like Sandisk Ultra advertise 15MB/s is only a maximum read speed, and write speed still guarantees only at its class range (Class 4 in Sandisk Ultra's case).
So Speed Class is a stringent guideline on the minimum possible transfer speed, am I right?
Erm I'm using the GF-1, and reading its guidelines it says when recording HD movies, it is "recommended that you use a high-speed card of "10MB/s" and above".
If that's the case, only a class 10 card is able to record HD movies? (Like Sandisk Extreme)
I don't want to spend money unnecessarily on a high speed card... Afterall the GF1 only bursts a maximum of 3 shots/sec... nothing a Class 4 can't handle...
Thanks in advance for all your help and advice.
