sebastian Posted October 17, 2008 Share #1 Posted October 17, 2008 Advertisement (gone after registration) I'm having trouble finding meaningful user reviews of various brands of SD and SDHC cards. It seems the negatives fall into three broad categories, brought about by the differences in the two formats: 1) The card doesn't work at all.. from, I suspect, users who buy an SDHC card for a camera that doesn't support it. 2) I can see the pictures on my camera, but I can't load/read them on my computer... from, I suspect, users who's reader (built in or separate) doesn't support SDHC. 3) And... mysterious, intermittent problems... from users who, I suspect, delete images and format cards in their computer, rather than in the camera. I've had zero problems using cards from cheap (Transcend) to middle (PNY) to high-end (SanDisk) in my DL3. Am I just lucky? Or am I risking losing everything by using less expensive cards? If you KNOW your camera and reader support SDHC, and you format your cards in camera... have you experienced any major issues (or lack of) with any particular brands of cards? Or all they all basically the same? Thanks, Dave Link to post Share on other sites More sharing options...

geoff Posted October 17, 2008 Share #2 Posted October 17, 2008 No, they are not all basically the same, but reliability and compatibility between SDHC media and devices has been greatly improved upon over previous SD specifications. One main issue that plagued the Secure Digital format, prior to SDHC, was the loose conformity exercised by manufacturers in both the design and marketing of products, which resulted in incompatibility issues and consumer confusion. A primary intention of the SD Specification Version 2.0 (SDHC), set forth by the SD Card Association, was to rein in previous dubious practices by significantly strengthening and enforcing mandatory manufacturers’ compliance. Therefore, for all intended purposes, unlike some previous Secure Digital media, a properly certified and labeled SDHC memory card should function accurately, within it’s rated speed class, without issue. The important, but hidden, differences between SDHC media, aside from price and speed classification, comes down to construction and the selection and quality of components used; including the controller, type of memory cells and electronic component incasement. These are areas that are often overlooked or considered but play a major part in overall durability and long term reliability. The fact is that many high grade SDHC memory cards can now be obtained for less than what low grade SD memory use to cost not too long ago.

farnz Posted October 17, 2008 Share #3 Posted October 17, 2008 FWIW, I have switched to 8GB SDHC cards (Sandisk) in my M8 and transferred my 2 4GB Transcend SD cards to my D-Lux4. One of the 4GB SD cards is 150x and the other is 133x and both worked flawlessly in my M8. My D-Lux4 works well with the 133x it will not recognise the 150x. Weird. Pete.

geoff Posted October 17, 2008 Share #5 Posted October 17, 2008 FWIW, I have switched to 8GB SDHC cards (Sandisk) in my M8 and transferred my 2 4GB Transcend SD cards to my D-Lux4. One of the 4GB SD cards is 150x and the other is 133x and both worked flawlessly in my M8. My D-Lux4 works well with the 133x it will not recognise the 150x. Weird. Weird? Maybe, but not surprising given that the two Transcend 4GB memory cards mentioned conform to neither any industry standard Secure Digital or current SDHC specifications as ratified by the SD Card Association. In fact, Transcend actually changed the labeling on their packaging of these memory cards to read “SD Compatible” from the previous Secure Digital reference. Basically, theses cards piggyback on top of the SD Specification Version 1.1 by grafting on FAT32 file allocation support. However, they are based on byte addressing as opposed to sector addressing as provided by the SD Specification Version 2.0 (SDHC). The difference, as I understand it, plays a large role in facilitating increase write speed. Geoff myspace.com/geoffotos Link to post Share on other sites More sharing options...
farnz Posted October 17, 2008 Share #6 Posted October 17, 2008 Thanks for your response, Geoff, and I take your point but I mean weird from the point of view that they both work in my M8 but only the slower one works in my D-Lux4. Pete. Link to post Share on other sites More sharing options...

USA road racer Posted January 13, 2009 Share #8 Posted January 13, 2009 According to the owners manual, the D4 can use up to a 32G SDHC card. I think you may need to format the card. Link to post Share on other sites More sharing options...
stuny Posted January 13, 2009 Share #9 Posted January 13, 2009 Dave - One more variable: Counterfeit SD cards have been on the market for some time, and we can assume that counterfeiters will do the same for SDHC. This implies that one should buy them only from very reliable sources. Link to post Share on other sites More sharing options...
miami91 Posted January 13, 2009 Share #10 Posted January 13, 2009 Unless you're just trying to find the cheapest (compatible) cards possible, I can give an enthusiastic recommendation to Hoodman SD cards. RAW Secure Digital-Hoodman Corporation Since finding out about these, I've replaced all my SanDisks with them. Top quality and made in the USA. They're expensive, but well worth it for practical and philosophical reasons. At the risk of sounding/being jingoistic, I think its important in these tough times to support American jobs. Jeff.

wparsonsgisnet Posted January 13, 2009 Share #11 Posted January 13, 2009 Dave, I recommend the Transcend 8GB SDHC Class 6 card, enthusiastically. First, they cost less than $15 (today, $11 and change) on Amazon. Second, they work fine. I bot one to try and followed up with 2 more. These things are so cheap that maybe no one wants to both selling bogus ones. Link to post Share on other sites More sharing options...
CX827 Posted January 15, 2009 Share #12 Posted January 15, 2009 Kingston is another cheap alternative compare to SanDisk. And i've been using the 8gb SDHC one for awhile, so far so good. It may not as fast as SanDisk, but heck, the price is relatively cheap, so no complain and yea, as stuny mentioned above. there many counterfeit SD cards out there, didn't realize that b4 until i do my homework.
