"The test beds for this review will be my Konica Minolta DiMage Z5 5 Megapixel digital camera and a SanDisk 12 in 1 Flash Memory Card Reader/Writer. To measure speed and performance on the computer I used HD Tach RW v.3.0.1.0. As you can see from the chart below at the lowest resolution and picture quality this card will hold an amazing 14,323 pictures and even at the highest resolution and quality it will hold 773 shots. That's the equivalent of more than 21 rolls of 36 exposure film. Please keep in mind that these numbers are calculated and can vary as you take pictures. Video ranges between 23 minutes to over 1 hour."
