Since I shoot with my DSLR exclusively in RAW format and 8GB sand Disk Extreme (60MB / s) began, I was looking for a way to get the information as quickly as possible to the laptop. After a long search and browse various forums I have decided to use this card reader. The speed is excellent, is in the top of 56MB / s and remains when reading> 1GB always about 44MB / s. Here the limiting factor is likely to be the internal hard drive of my laptop. Changing the CF card causes this is not recognized automatically. In order to change the ExpressCard to be removed and re-inserted. A driver installation was fortunately not necessary. I put the card readers on Windows 7 Ultimate 32-bit one.
The speed has clearly earned 5 stars, I would have taken off for handling only 1/2 star, as this does not go, I forgive very good 4 stars.
