Sandisk Compact Flash Extreme Pro 32 Go

Product Survey: Compact Flash Cards

Be careful, though, because not all memory card readers will be able to support such high speeds. An Express Card adapter which can handle UDMA 6 is also available and can plug straight into some laptops. Another, for desktop computers, should arrive soon. Because we didn't have either, we used a SanDisk Extreme FireWire 800 for our tests. Once again, SanDisk astonished us with record-breaking speeds. Although this card didn't quite manage to reach the speeds promised in its specs, it got pretty close. The Extreme Pro wrote photo files at 32.8 MB/s, which is 10 MB/s faster than its competitors. For reading, the gap is even more noticeable. SanDisk's latest card was at 60.5 MB/s, while others trail behind at 40 MB/s. Sandisk CF Extreme Pro 32 GB Transcend CF 400x 64 GB
