I didn't want to review this card by anecdote alone so I used some testing software and compared this amazon 16GB Class 4 card to others I had handy and here are the results:

Amazon.com SDHC 16GB Class 4
AmazonBasics 16GB Class 4 SD Flash Memory Card
Warning: Only 500 of 15140 MByte tested.
Test finished without errors.
Writing speed: 6.44 MByte/s
Reading speed: 12.5 MByte/s
H2testw v1.4

HP Branded SDHC 16GB Class 4
HP 16 GB Class 4 SDHC Flash Memory Card Q6305A-EF
Warning: Only 500 of 15185 MByte tested.
Test finished without errors.
Writing speed: 13.1 MByte/s
Reading speed: 17.5 MByte/s
H2testw v1.4

RiData SDHC 4GB Class 2
(No longer available in Class 2 category)
Warning: Only 500 of 3805 MByte tested.
Test finished without errors.
Writing speed: 4.00 MByte/s
Reading speed: 11.7 MByte/s
H2testw v1.4

As you can see, the Amazon card is about 50% slower as the HP card in write speed and 30% slower in reading yet the cost of the Amazon card is 25% higher. Even compared to the old RiData SDHC 4GB Class 2 card the Amazon card is only 30% faster in writing and marginally faster in reading speed. Why is that?

The Amazon card may be adequate for it's class and full retail price point but when compared to the competition there are better choices to be made.

Amazon will need to demand a higher quality product from its suppliers if it wants to compete in the market with its own branded product.

I really like this SD card. Although it is rated Class 4 (i.e., sustained write speeds of 4 MB/s), my testing revealed it to perform more like a Class 6 card (sustained write speeds of 6 MB/s). Check out my results using H2testw v1.4 (I also tested a Transcend 16 GB Class 10 SD card I own as a benchmark & for comparison. I ran two tests on each card):

TEST 1

Amazon Basics 16 GB Class 4

Warning: Only 15139 of 15140 MByte tested.
Test finished without errors.
Writing speed: 5.60 MByte/s
Reading speed: 8.58 MByte/s
H2testw v1.4

Transcend 16 GB Class 10

Warning: Only 15378 of 15379 MByte tested.
Test finished without errors.
Writing speed: 9.21 MByte/s
Reading speed: 11.9 MByte/s

TEST 2

Warning: Only 15139 of 15140 MByte tested.

I like it when something performs *better* than it's rated specs! ;o) I would recommend this card without hesitation to family & friends...

The card certainly has capacity to spare, even shooting RAW files. However, like many of you I enjoy taking photographs at sporting events and that is where the difference between a class 4 card and a class 6 card (which I have several of) shows up.

The slower writing speed on the class 4 card, and slower transfer speed when off-loading the images to my computer, is disappointing ~ enough so that I will sacrifice capacity for enhanced speed when making future purchases.

I love to take photographs and have been shooting for over 40 years. Memory cards may seem expensive but when you think about what we used to spend on film, processing and printing they seem pretty reasonable.

My more serious digital SLRs use Compact Flash cards but my point n' shoot and my video cameras use SD cards. I was a little unsure as to how this card would work (I received the 32GB Class 4 model) for me, especially since my video camera is capable of shooting in full 1080i HD mode and call for a Class 6 or better card. I have using this for a week and found that, although it is a little slower when loading, it works just fine when I am shooting or recording at my camera's highest resolution.

I just shot a couple of videos of Hulk Hogan (he was in town for a commercial and although I am not a wrestling fan I thought that it would be a good chance to try my new memory card out) in HD and they turned out great. I only noticed a small lag time when switching modes on my Samsung HZ15W camera. I posted them on YouTube and they looked really good for that kind of casual video.

As for the packaging; I can't say enough about Amazon's Frustration-Free Packaging! I hate it when I buy a memory card and spend 10 minutes or so trying to get the silly thing open. Those large plastic sarcophagi that they use to protect the cards from theft usually require a knife or a pair of scissors in order to free your newly purchased item. I guess that I can understand them doing that for at a retail shop, but when you order it on-line it's just not necessary.
