 Special Tests  

CF FireWire Reader

The test setup:
SONY 300x UDMA CF 8GB, NCFD8G
Hama 55352 CF FireWire reader, Oxford FW 912 controller
TI TSB82AA2/TSB81BA3 FireWire, TI OHCI 1394 Driver
Read/Write directly from/to the media, no filesystem involved
Read/Write rates taken with a sample size of 4MB, 1908 samples

The test showed an average trasfer rate of 43.11MB/s (294x) read and 38.32MB/s (261x) write.
Please note that my current FireWire host/driver setup seems to be maxed out around 38-39MB/s write rate. As the results with the CF-SATA adapter show, the card can write faster.

CF to SATA Adapter

The test setup:
SONY 300x UDMA CF 8GB, NCFD8G
CF to SATA adapter with Marvell 88SA8040-TBC1 controller
ICH6R SATA Host
Read/Write directly from/to the media, no filesystem involved
Read/Write rates taken with a sample size of 4MB, 1908 samples

The test showed an average rate of 42.87MB/s (292x) read and 46.30MB/s (316x) write. These figures are correct, the card can be written faster than it can be read.
