Default SD Card Speeds

On my FZ10 the following delays before another shot can be made after a 5 shot burst are:
Sandisk 256MB: 10.8 (seconds)
Panasonic 16MB: 5.8 (seconds)
Sandisk Ultra II 256MB: 2.4 (seconds)

Big difference as you can see.

Perhaps others can time the recovery time of other brand SD cards.

To make a fair comparison, the size of the cards should be the same. I can only speak for Panasonic, but in our case the speed of the card increases with the size. At 256 and larger the added speed will only be realized with devices like our SV-AV100 that's capable of recording real time MPEG-2 video.

Digital cams are based on the 2 mb transfer rate, so seeing one cards performance being significantly slower suggests the card may be rated below that value. Burst mode will use the buffer in the camera, so while the camera may take slightly longer the images won't be lost.

Wow! I didn't think there would be that big of a difference in-camera. I read somewhere that the FZ10's internal buss speed was 2MB/sec. I'd be interested if anyone has done similar tests with different brand cards. Was this at the full quality level? What was the average file size?

OK, I just ran a test on my Kingston 512MB SD card. There were 5 files averaging 1.56MB each. From the last shot to the time the camera stopped writing to the card was a whopping 12 seconds
.

Just did a few more cards of various sizes.
Each card was formatted before the test and the camera had achieved focus lock before fully depressing the shutter.


I-O Data 64MB average file size 1.42MB 7 seconds
Memorex 128MB " 1.52MB 10 seconds
Sandisk 256MB " 1.52MB 12 seconds

I ran the I-O Data test twice, and for some reason the file size was a little smaller than the other 3 cards on the same subject.

Lexar 256MB (32X) - takes about 3 - 3.5 secs after 5 pictures in burst H mode.
Not too bad, somewhere between the "plain" and the "ultra".
