Speed Sdhc
Posted on Monday, June 14, 2010 in Photography
how do you find out the speed of sdhc memory cards?
I need to get a sdhc 4gig or high memory card, with a speed of at least 10mbps. I found lots that have a class 6 rating, which means a minimum of 6mbps. Will a class 6 work in my camera?(Panasonic dmc-lz7)
Your camera will work with any Class rating of SDHC, but the faster cards can write your photos and video to the card faster, so you can take the next shot faster or keep shooting visdeo for longer before your buffer is full. See this video for a demo http://www.youtube.com/watch?v=ACUnPfVuBZg
Write speed is what is important, not read speed.
Up until a year ago, SD cards were faster at write speeds than the SDHC cards as per this article http://flash.atpinc.com/news/extremetech_sdhc.pdf None of the cards had 10mb/s speed.The fastest had a 8.34mb/s write speed. See http://www.robgalbraith.com/bins/multi_page.asp?cid=6007-8531
though SDHC cards are getting faster now, with some class 6 cards reacching 16mb/s http://www.hjreggel.net/cardspeed/speed-by-cards-sdc.html
