Memory card speed for GH1

Class 10 is faster than Class 6.
I would get 8gb for video.
I use 4gb but just do stills.
Some say there's no difference in speed but there really is.
I tested on the Pens and G1/GH1....
I see a difference.

It might be slightly more complicated than that. There sometimes can be no difference.

The class rating is a "minimum speed". As a result there are class 6 and class 10 cards that run at the same speed as well as class 6 cards that run faster than class 10 cards.

As an example, a Sandisk extreme III 30mb/s class 6 card, compared to a cheap generic no-name brand class 10 card that runs at 10mb/s.

The other glitch is sandisks claims of 30mb/s is "maximum" which means you can get varied speeds between 6mb/s to 30mb/s in actual usage, so sometimes you'll beat 10mb/s, other times you'll be slower than it...

 

True enuff...
I have the class 10 Sandisk cards and I use then but don't like Sandisk cards.
My Lexar Pro class 6 cards are almost as fast but not as fast.
I had major issues with Sandisk in the past. Never had a single issue with any Lexar card in any format.
I'm not sure Lexar released the class 10 SDHC yet.
When they do I'll get them and sell the Sandisk.

The write speed of the camera has more to do with it than the card....

 

Hi

I use a SANDISK Ultra HC II, 15MB/s Class 4.
It is fast enough for making movies in any setting.

 

It will work but it's not a speed demon....

Class 10 cards are cheap now....

 

We have a nice long discussion about this here: "Has Anyone Done Memory Speed Comparisons?" for your reading pleasure in the Accessories forum.

 

I've used several class 6 cards with my GH1 (Kingston, SanDisk, and one other brand I can't recall offhand). None have given me any trouble when recording video. Most of the time I'm shooting short (~ 10 second) clips, but occasionally shoot several minutes continuously.
