Lexar 256MB SD cards

[ScottG]

Can anyone tell me the difference between the Lexar SD256-32-231 and the Lexar SD256-32-266 other than about a $3 price difference?

Not sure what the 2nd part number is, but Lexar makes 2 256MB SD cards: One is SD25632231 a 32X speed card and the other SD256231 a non 32X speed card.

From Lexar's FAQ page:

Because digital film WRITE performance is so important in capturing the right picture at the right moment, Lexar Media has implemented an easy-to-understand system to indicate the speed at which the card is capable of storing data. The system is adopted from the CD-ROM industry, in which the performance of CD-ROM drives are rated in "X" increments, where 1X is equal to a minimum sustained write speed of 150 kilobytes (KB) per second. Lexar Media will continue to introduce faster products with greater "X" ratings, giving consumers an easy way to recognize the latest in high-performance digital film.

4X = Capable of 600KB/sec. Minimum Sustained Write Speed
12X = Capable of 1.8MB/sec. Minimum Sustained Write Speed
16X = Capable of 2.4MB/sec. Minimum Sustained Write Speed
32X = Capable of 4.8MB/sec. Minimum Sustained Write Speed
40 X = Capable of 6.0MB/sec. Minimum Sustained Write Speed
