16GB or 32GB SD Cards

by johnnyo1970 Feb 6, 2010 9:43PM PST

I have a Kodak 12MP digital camera that also shoots in HD. I was trying to figure out the best 16GB or 32GB SD cards to use but cannot find real reviews in regards to transfer speed and write speed. I have read some customer reviews are sometimes biased towards one company to another instead of stating what actually is technically superior for HD shooting, can someone guide me to what they find works when shooting in HD with kids moving around, I don't want to miss the shot, Thanks John

SDHC cards

by snapshot2 Forum moderator Feb 6, 2010 11:20PM PST

All SDHC cards are built to meet the specifications put out by www.SDcard.org

Here is what they have to say:

http://www.sdcard.org/developers/tech/sdhc/

What you are looking for, you will not find.
What works best on one camera may/may-not work the same on another camera.
And it will vary between manufacturers of cards.

There was one site that tested memory cards on actual cameras.
They mostly tested them on DSLR cameras.

The testing became so expensive, they abandoned the project.
Consider the large number of cameras (which increases each year) and the large number of manufacturers of cards (which increases each year), the cost became too great.

Just be careful where you buy memory cards.
There have been many reports about counterfeit memory cards being sold on eBay.

HD video memory cards

by hjfok Feb 7, 2010 1:25AM PST

I use the Lexar professional 300x UDMA CF card for 1080 HD video with my Canon 5D Mk II (21MP). It is fast enough for my video without any problem. I have not tested the max video time, but I can shoot as long as I want, though typically I don't shoot more than 10-15 min each time. I use my HD camcorder for longer clips.

They have a new faster card now with 600x but that is not necessary, probably an overkill.

The 300x card now costs a lot less than before, about $115 adorama.com. The 600x card costs about double.

Here is an approximate chart from Sandisk about how long you can shoot video on the card, depends on how many Mbps your camera's video use. You need to scroll down to see.
