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.
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.
More information will follow, see the Explanations for the Special Tests for details regarding the test procedure.
