I'm using a sandisk 8gb class 4 in a 600D...i can record longest is 30secs per clip b4 it stops automatically...is it normal? Or it can actually record for longer duration per clip?  Shud I get a better card? Some advice needed, newbie in HDSLR video recording smile.gif

I have a Transcend 8GB Class 10. Initially it has no problem shooting Full HD videos continuously but after I format the card once with my Canon 60D, the same problem as yours started to occur. doh.gif

Btw, I will be bulking some 16GB Sandisk Extreme HD Video 30mB/s (200X) read/write at very good price. Stay tune. tongue.gif

from the market price the gap is not too much(the last time i see,or the 30mb/s version getting cheaper?) and the uhs-1 is effective for camera that utilize the new buses,like nikon d7000

I will make sure my 16GB 30MB/s price will have quite a distance from 45MB/s. laugh.gif

Interested in your bulk of 16GB Sandisk Extreme at good price  drool.gif
BTW, any different between SanDisk Extreme HD Video SDHC & original SanDisk Extreme SDHC Class 10? Are they same Classes?
Also, found that there are 2 models of SanDisk Extreme HD Video SDHC, 1 is 20 MB/s & 1 is 30 MB/s. Are their Classes different?
Thanks in advance.

Class is the minimum speed the card will read/write - Class 6 mean the card should be able to do at least 6MB/s, Class 10 at least 10MB/s., etc. I am not really sure why but i think the higher Class base rating is max at 10 at the moment and the standard will move to UHS Speed. Please do correct me if I am wrong coz I am not 100% sure about this speed rating.

So even if the cards are the same at Class 10, some will write at the minimum 10MB/s while other may write faster at 15MB/s, 20MB/s, 30MB/s or 45MB/s. To distinguish itself from the normal Class 10 card, some manufacturer like Sandisk states more accurate speed rating - 15MB/s, 20MB/s or 30MB/s on their Class 10 card. So even though 20 MB/s and 30MB/s SanDisk Extreme HD Video SDHC are both Class 10, their writing speed are definitely different.

EDIT: Please check my bulk thread at my sig below. smile.gif

if my camera transfer speed is slow, even class 10 sdhc doesnt help as well right?

if you are talking about transferring photos from your camera to PC then you can remove the SD Card from camera and use a card reader to transfer. In this case, fast card reader and fast SD Card will make a difference. smile.gif

cynox, wat im saying is from camera to SD card

what camera are you using? So you are saying the writing speed of the SD card when you take the pictures? Do you know what is the writing speed of the sd card of your camera?

hey guys, what's the difference between class 10 and class 6 SDHC? Is the read/write speed?

I already posted that info in previous pages...

Not recommended for Canon EOS 550D, 600D and probably 60D too due to incompatibility issue.

Sandisk Extreme HD Video Class 10 30mb/s confirmed no problem. Tested with 60D and 600D. nod.gif Best for full HD recording. thumbup.gif
