It really works on my MBP 15 Retina! It also promises, on paper, much faster transfer rates to and from your compact flash memory cards than standard USB 2. The design also provides card stability and prevents any shifting during reading. This driver has it working again under El Capitan. I think I made the right one. One thing that I feel could be improved is the instructions for installing the software driver.

Read on for a possible solution. Frank Nuernberger October 13, at The main culprit is the hard disk; not only do laptop hard drives spin more slowly typically RPM compared to RPM with desktop drives but the larger diameter desktop hard drive disks mean that more data passes the read-write head on desktop hard drive in a given time than a smaller laptop disk.
We also generally saw faster speeds for writing to the cards than for reading, which also suggests that when draw data off the cards a bottleneck occurs when the data is being written to the hard disk.
