SanDisk SDCFX4-4096-901 4GB Extreme IV CompactFlash Card
I bought this for a DSLR to have more room that the previous 2GB ExtremeIII and more speed with continuous shooting mode. The Memory Card has preformed flawlessly.
Cons: I have already had two occasions where I have filled it with pictures while shooting. A lot more bad pictures to weed out.
Rating: - Excellent Performance, Super fast write speeds.
Excellent Performance, Super fast write speeds. Have tried several other brands and types, this product beats write speeds on camera when compared to several other products I have used. Recommend this to anyone wanting to use with a digital DLR or digital camera.

SanDisk 4GB Extreme IV CompactFlash Card.
I'm liking the speed of this flash card and thinking about picking up another one.
Rating: - Great card! Reliable.
This is a great memory card. Reliable, very, very fast, and with enough capacity for most needs. I just wish SanDisk's rebate program didn't take 90 days to deliver.
Rating: - i have 2 of these, plus the 8gb version on it's way!
i never, ever had any problems with sandisk. that's why i keep coming back to them because of the quality. the extreme iv is the fastest yet (well the ducati version is faster). if you have a pc/mac with firewire 800, i suggest getting a firewire card reader from sandisk. it'll transfer the images to your computer very, very fast!
