Digital camera reviews of Kingston 4 GB SDHC Class 6 Flash Memory Card SD6/4GB
Digital camera Review: Bad Card
Summary: 1 Stars
I bought this card along with a Panasonic Lz8 digital camera and much to my chagrin, the card had a memory card reading error. I formatted the card but it did not help. I bought the card for a little over $10 so it's not worth my time to send it back or try to get my money back. I'll chalk it up as a lesson to not buy Kingston Memory again. I have used Sandisk in the past and they work great. I put in an old 512k Sandisk card in my Panasonic Lz8 and it seems to write just as fast as this card. I guess you really do get what you pay for!Digital camera Review: Bad news
Summary: 1 Stars
Lot number 4174139 made in Taiwan. Of course you can barely read it except in broad daylight. When a camera could read and it did work and then it didn't, I believe that is called failure. Nothing will format it now including the camera. So this review is for those who care about their pics. Luckily I had just moved a recent batch off before it crapped out. I had always been a fan of Kingston, but it just goes to show. I bought three of these, now I am wary of the other two. And yeah, it is not a question of the lock being engaged, but I suspect that element is somehow involved in the failure.Digital camera Review: Broke down twice already
Summary: 1 Stars
Probably I got the bad one, but this thing broke down twice already, with all my vacation pictures in it, twice gone. Money is not the issue here. But there is no way I can get back those vacation pictures again. Before I used the card I already formatted it with my digital camera so compatibility should not be any issue at all. THe first time it broke down, both my computers cannot recognize it so I ended up has to reformat the card again. The second time it cant be recognized at all leaving the card useless and all the pictures in it unreachable. Save yourself and buy better card. You dont wanna end up losing your pictures just for the sake of this cheapo card. I am warning you, dont be like me, lesson learned the hard way..Digital camera Review: Buyer Beware, Get What You Pay For
Summary: 1 Stars
Summary: Kingston Class 6 (6MB/s) card being sold at barely Class 4 (4MB/s) performance, yet it still can't keep up with the real-world performance that an older Panasonic Class 4 SDHC can deliver. I rarely ever leave reviews, but when a major brand misrepresents..
Bottom Line: I am requesting a refund, thank you Amazon! I will also never pay a premium for Kingston memory for my cameras, workstations, or servers, nor would I recommend it to my friends or even strangers! The performance is probably not noticeable in non-streaming applications and smaller digital cameras, so mileage may vary.
Real World: I bought this card for a new handheld Aiptek 1080P GVS video camera and all was perfect at 720P 60fps, then I switched it to 1080P and kept getting an error with the camera stating "slow memory card" within 1-2 seconds of recording.
The camera requirements is only for Class 4, but is compatible with Class 6, I purchased the Class 6 for the extra performance and as a good solid baseline performance against a future generic brand 32GB card purchase.
So I went and found the biggest SDHC card I could find from an old camera, a Panasonic 2GB Class 4, and the camera worked perfectly, swapped back and forth, did a format on the Kingston, same results every time.
So I downloaded H2testw which is primarily a capacity test, but also reports sustained read/write performance. I tested both cards on a Windows system in the camera using the USB cable with the only variable being the SDHC card itself.
To summarize the Kingston website - SDHC cards can be rated different ways by different manufacturers, but a class 4 is supposed to be at least 4MB/s, and a class 6 is at least 6 MB/s. The rating can be based on write speed, read speed which is typically faster than write speed, or some combination referred to as transfer rate. Kingston states that their ratings are based on write performance.
So here are the results which runs for several minutes since it also verifies capacity:
Kingston 4GB Class 6
Warning: Only 3846 of 3850 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 3.58 MByte/s
Reading speed: 6.50 MByte/s
H2testw v1.4
Panasonic 2GB Class 4
Warning: Only 1834 of 1921 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 3.36 MByte/s
Reading speed: 6.22 MByte/s
H2testw v1.4
I also tested a micro SD 8GB sandisk card from my cell phone that went at 16.1 MB/S writes, 18.3 MB/S reads.
So the difference is that the Kingston is only 6% faster on writes, and 4% faster on reads against a chip where it should be at least 50% faster. I never considered Panasonic a leading brand, let alone the #1 perceived brand.
The bigger difference is that even though overall performance is really about the same, the minimum write performance must be much lower than the average in order to cause a recording error with the camera.
As another reviewer said, the Kingston brand is not what it used to be..
Digital camera Review: Does not work
Summary: 1 Stars
Bottom line, Save your money and stay away from this memory card.
After buying a new Cannon digital camera, I started looking around for a reasonably priced SD or SDHC card. Sandisk and other recognizable brand names were selling for about $30 at brick and mortar stores. So I decided to check online and found some great deals on Amazon. It did cross my mind that the prices might be too good to be true.
I should have listened to my inner voice. After receiving the Kingston 4 gb sdhc in the mail, I put it into my camera. The camera showed 3.9 GBs available. That's fine, I thought. So I took a couple of shots and was able to review them. Then I turned the camera off and that's when the trouble began. When I turned on the camera a few hours later, the camera displayed a memory card error. Removing the card and re-seating did not work. Wiping the connectors on the card did not work. Nothing I did fixed the problem, except going out and buying a new card.
