SD cautionary tale
I thought I was a pretty savvy e-consumer, but I'm in the embarassing position of posting this warning:
We all (should) know about the abundance of defective, bootleg SD cards out there. The advice to only buy from a reputable e-merchant is all over these and other forums. So I did. I bought a SanDisk Ultra II 2GB card about 3 months ago. Paradoxically, the problem was that it worked.
The reason that turned out to be a problem is that I only recently tried to use the card to write an audio stream, and my write rate was well below spec. I used CardSpeed (a read/write tester that comes bundled with Audacity) and it turns out that the data transmission rates were from 1/4th to 1/20th what the card should've been! I called SanDisk and, sure enough, the serial # confirmed that it wasn't one of theirs. Fortunately American Express is taking care of me.
SO... if you buy an SD card don't just see if it works; check the data transfer rates right away. Malicious e-merchants are probably counting on you not discovering the fraud until much later. According to SanDisk, even well-reviewed e-merchants can end up with knockoff media stock. My solution: I bought from B&H, a discount e-merchant with an established physical store in New York.

Damn, how can I check that? I just bought a new 2Gig SanDisk card from Antonline.com through Amazon and a SanDisk Card Reader ImageMate yesterday. The price that I got it [SD Card] at seemed like a steal too, enough that now I'm supicious after reading this.

You can download the card speed testing utility separately (free) and simply tap the "Test" button. It'll rate the card performance. When interpreting the numbers, don't forget: 8 bits per byte and 1,000,000 bytes per megabyte.

Great, Thanks, I'm on it. Hopefully everything is all good!

I ran it on the 128MB SD card I have & it passed with the following message Card Speed is Good Avoid 22KHz ADPCM

Sounds fine. Test the 2GB card when it arrives.

Appreciate the good warning kabeyun. For what its worth, I read the other day about a lady who writes articles for a large newspaper about internet scams, and how not to get scammed. She got caught up in a phishing scheme herself!! Talk about embarrassing!!
I picked up a 2 gig ultra sandisk for my camera @ CircuitCity last Friday for $80 with two $20 rebates! $40.00 after rebates put a big ole smile on my face!!

Good deal. Is it an Ultra or one of the plain blue SD cards?
