We have been using SanDisk Extreme cards for 8 years now. We average 30k to 40k images per year. None of the cards has ever had an issue, even in hot, humid south Texas. It is nice to see some companies still value quality, and I am willing to pay a premium for it.
Get exactly the shots you want with professional-grade SanDisk Extreme® CompactFlash® cards. With up to 60 MB/s* read/write speeds, you'll see it takes more than a great digital SLR camera to bring your ideas to life. And with up to 32GB** of space, you'll have room to capture it all in RAW+JPEG, and save the editing for later.
SanDisk engineered its Power CoreTM Controller to take whatever your camera's buffer can dish out. By distributing image data across the card more rapidly and efficiently, this card delivers professional performance.
