SanDisk really stands behind its products.
I bought this SD card 2 1/2 years ago for use in my Magellan Meridian GPS receiver. Worked great until last month. Went to SanDisk's website for help. The tech support people had me go through some diagnostic procedures and determined that the card wasn't fixable. They arranged for me to return the card to them and even paid for shipping by FedEx. Two days after they received my old card, a new one was on its way to me. Just received it today and it works like a charm.
It sure is nice to do business with a company that stands behind its products and cares about its customers.

* How many pictures will it store? ...
How many pictures will it store? It is the most commonly asked question from digital camera enthusiast but usually the question that is the most difficult to get a straight answer about. Well, considering I worked in the memory industry for over 7 years I can help clarify this perplexing question and do so unbiased as I have since changed industries.
The SanDisk SDSDB-128-A10 Secure Digital 128MB, like most 128MB cards, will store on average 142 pictures when used with a 2 megapixel camera, 106 images when used with a 3 megapixel camera, 64 pictures when used with a 4 megapixel camera, 51 images when used with a 5 megapixel camera, and 40 pictures when used with a 6 megapixel camera. These numbers are based off the assumption that you are going to shoot your images at the highest quality JPEG setting available for the camera and understand that they are estimates and may be off by as much as 10 percent due to numerous factors including the complexity of the scene being shot and the compression algorithm used by your specific camera.
I truly hope this review was helpful to you in determining whether this card is the right capacity for your specific needs.

A good product for my Toshiba pda
I bought it for use on the Toshiba e755 six months ago. I did not find any problem. It runs surprisingly fast, so I put a lot mp3s in it and my pda can be used as a small size ipod :)

* Unbeliveable!!!!!! ...
I bought this memory for my HP Photosmart 320 2 years ago. Since then I have traveled to Paris, Ireland, Hawaii, and a few southern states. Overall I took 10,000 pics w/ this camera and its trusty 128 mb san disk memory. It has performed wonderfully for all of these trips. I recomend this item for any Digital photographer.
