Digital camera reviews of Kingston 4 GB SDHC Class 6 Flash Memory Card SD6/4GB
Digital camera Review: Works Great, No Problems
Summary: 5 Stars
I bought this for a Nikon L20 10-megapixel point-and-shoot camera.
It works fine and I've had no issues.
I'm not sure what the high speed gets me since I am not using all that sophisticated of a camera, but it seems responsive enough.
The only downside I have discovered is that the SD card reader in my two-year-old Dell PC is not SDHC-compatible. Meaning it will not recognize a card of this capacity. It's kindof a bummer, but I have a newer laptop that reads this 4GB card fine. This is not the card's fault, but you may want to verify what your computer will handle before you move up to SDHC.
All in all, I am satisfied with Amazon service and pricing, as usual. I recommend the Kingston 4GB Class 6 card without hesitation.
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: Kingstons best product
Summary: 5 Stars
This one really performs as described by mnf. and this one performs better then I thought. On my SX200IS it can store more then 10k pic on M3 mode which Canon spec's state that an 8gb sdhc will hold about 8k at that mode.
So far so good with out any issues and very happy with class 6 SDHC card.
