Photo Forum / Digital Photography / Digital Photo / September 2005Secure Digital Recommendations
To All: I recently purchased a new camera that uses Secure Digital and I am asking for some recommendations on reliability of different brands of Secure Digital memory. I am looking at 512 MB. I have been using Compact Flash for over 4 years with 2 different cameras with a preference for Lexar. I mainly shoot stills so write speed is not an issues. What brands of Secure Digital do you recommend for reliability and what brands to you recommend that I avoid? Thanks, Steve [] > What brands of Secure Digital do you recommend for reliability and > what brands to you recommend that I avoid? Work well for me: SanDisk Ultra II, KingMax Platinum Avoid: (non specifically - but I would avoid off-name, cheap brands) David [This followup was posted to rec.photo.digital and a copy was sent to the cited author.] > [] > > What brands of Secure Digital do you recommend for reliability and [quoted text clipped - 4 lines] > > David My daughter has a Transcend x45 1 Gb in her Pana which works very well and is usually a lot cheaper than the main name brands. (Their current model is x80 speed).

I must admit that I have had problems with "off brand" PC memory so I tend to stick to the "name brands" these days.

Bruce: Same here! With Compact Flash, I have found the basic Lexar card to be faster than the basic Sandisk card. Is that the same for Secure Digital? Steve >To All: > [quoted text clipped - 12 lines] > >Steve Here are a few of my notes on SD cards. I was unaware of all the memory speeds available. Believe me a 133X will really make your camera seem fast and well worth a few extra $ up front. The higher the speed rating, the faster your camera will be able to write images to the memory card. 1X = 150 KB/sec 60X = 9MB/sec 66X = 10MB/sec 133X = 20MB/sec http://www.steves-digicams.com/flash_memory.html#sd SD cards range in size from 16MB up to 2GB. As with other flash media, SD cards come in different transfer speed ratings. Most SD cards not marked "High Speed" or "Ultra High Speed" are probably only ~2Mb/s capable. The latest cards are capable of transferring data at 8-10Mb/s such as the ATP 60x, SanDisk Ultra III or Extreme cards. Transfer speed is an important factor if you record high framerate motion video or high quality audio tracks. Many digital camera makers only certify their 30fps VGA motion video capability when using "high speed" SD cards. Capacities: 64MB, 128MB, 256MB, 512MB, 1GB and 2GB SanDisk Extreme is 60X = 9MB/sec SanDisk Extreme III is 133X = 20MB/sec SanDisk Ultra® II is 60X = 9MB/sec (plus adds USB) >>To All: >> [quoted text clipped - 43 lines] > SanDisk Extreme III is 133X = 20MB/sec > SanDisk Ultra® II is 60X = 9MB/sec (plus adds USB) The weak link in the speed of a Camera-to-Card download is usually the Camera itself, especially with lower/mid level P/S cameras. High end DSLRs can usually keep up with most fast cards Where the more expensive fast cards shine is in Card-to-PC transfers when using a USB 2 Reader Bob Williams >>> To All: >>> [quoted text clipped - 50 lines] > when using a USB 2 Reader > Bob Williams Bob: Agreed!

So what about the reliability by brand? That was my original and ONLY question. I have already read the Steve's Digicams article. Steve >Rick: > [quoted text clipped - 4 lines] > >Steve I have no brand loyalty or any good statistics on reliability. I typically buy what is on sale at my time of need. My last SD card purchase was a 512 MB Pretec (a brand I had not seen before) for $35 from Fry's Outpost. I've had no problem with it so far. http://www.pretec.com/ http://shop1.outpost.com/search?search_type=regular&query_string=pretec&cat= >>Rick: >> [quoted text clipped - 13 lines] > > http://shop1.outpost.com/search?search_type=regular&query_string=pretec&cat= Rick: Thanks for the info. As I said earlier in this thread, I have had some bad experiences with "off brand" PC memory, so I am a bit cautious about "off brand" camera memory. Steve >> Rick: >> [quoted text clipped - 13 lines] > > http://shop1.outpost.com/search?search_type=regular&query_string=pretec&cat= Fry's had a 512 meg 'off brand' for $29 yesterday (no rebate needed). Last year I paid $64 for a 256 meg and thought it a great deal. sigh.

The camera is often the limiting factor in read/write speed, rather than the card. I rather prefer the Lexar cards, but it is more a matter of the fact that the Lexar cards I have are faster, and hold a bit more for the rated size (strange).

Well, Ron, that caught my attention. How in the world can one card "hold a bit more for the rated size" than another card? Are you saying that some "512MB" cards are more than 512MB? or that others are less than 512MB? SignatureDan (Woj...)

Card A: 512,000,000 bytes Card B: 512 * 1024 * 1024 bytes Card B stores 4.8% more. David |
