I picked up the Polaroid variant of this memory card as a doorbuster deal from Circuit City on Black Friday for about the same price you can find it here on Amazon. The model number on it is P-2D2G-RF3/POL. Therefore, I'm sure it's the same card with a Polaroid label. It says made by PNY on it. I bought it for use in the Nintendo Wii and I can verify that it is compatible. I've copied pictures to it from my PC and then viewed them on the Wii.

This is my first experience with Secure Digital as my camera uses CompactFlash. Therefore, I thought I would benchmark it for comparison. Using a cheap, generic USB 2.0 card reader, I copied a file containing 231MB of digital photos in JPEG format from my PC to the SD card. Write Speed is 2.89 MB/sec (231MB/80sec). I then renamed the file and copied it back to the PC. Read speed is 4.62MB/sec (231MB/50sec). For comparison, using the same card reader and the same testing method, my 1GB Sandisk Ultra II CompactFlash card showed a write speed of 1.67 MB/sec and a read speed of 2.78 MB/sec.

I don't really know how to rate this item as I have no experience with any other SecureDigital Memory. However, it works and it's much faster than my CompactFlash. Therefore, I'll give it a 4/5.

The card works as advertised, which doesn't include it's speed. It's not a fast card. But for general everyday use, you can't beat the price. For more demanding photography, I would recommend a faster card.

Please don't be fooled by it's inexpensiveness. I am a victim of it. I already bought this card and within 2 weeks I started getting read and write errors. I formatted the card and it now has 2 MB of bad sectors. Unlike the other reviewer I did had 2 GB to begin with. But I think it is bad quality product and thats why it is dearth cheap. It is not at all reliable. Now I am contacting their customerservice to replace this card for me.

I bought this card and a Magellan Explorist XL GPS from Amazon back in March or April. I plugged it in and it worked great ... until the other day when my GPS wouldn't start. I removed this card and the GPS started just fine.

Since there is (apparently) no software in the GPS to format the card, I decided to put it in my camera which does have format capability. The camera simply rejected the card as unusable.

Fortunately, I have a backup of all my map files and can hopefully restore them when I get a real card. I'm just glad I wasn't using it in my camera while on vacation.

Now I'm worried about my camera card which is also a PNY but the 1 GB version.

I think I'm going SD card shopping tomorrow.

I bought this SD Card on sale thinking I'd just saved a couple bucks, but the very first time I used it, it crashed my computer and broke my camera. After taking the pics I wanted, I inserted it into my computer, which instantly started acting strange slowing down and not recognizing that there was a card inserted. So I tried to restart my computer and it wouldn't restart. I had to take it in to get it fixed, costing me $100 for the technician to tell me it was the SD card. Also, the camera I used it in, a Nikon D80 that I just bought 5 months ago, is now being shipped back to the manufacturer for repair after using this card, the display monitor wouldn't turn on and the camera wouldn't record any pictures on any of my other SD cards. Next time, I'll spend a little extra money to buy something of quality, especially when using it with my expensive equipment.
