Guy Van Sanden wrote: [ ...in reference to USB 2 vs Firewire performance... ] Thanks for your answer. You're welcome. I was googling for this, and I found out that you need some modules: firewire.c fwohci.c fwohci_pci.c Yes, although FreeBSD 4.9 should have come with the module already compiled and available for use. See whether you have: /modules/firewire.ko ...on your system, otherwise add a "device firewire" and rebuild your kernel. I've used both the VIA 6306 and whatever Creative uses on the SB Audigy (Sony 3022? I forget)... Will the fwohci driver provide better perfomance then the USB one? Right now it certainly does. I was seeing data-level throughput of ~40 MB/s or 320 megabits per sec, which is ~80% utilization of the maximum available throughput of 400 mb/s. I don't know how much protocol-level overhead is involved, but there is undoubtedly some so it seems the Firewire driver works about as efficiently as one might wish.

Re: USB 2.0 harddisk performance
add a line to your kernel config file with : device ehci or options ehci... I'm not sure. Check your kernel config file, it should be the same as ohci! ... sorry I'm not in front of my fbsd box. Also don't forget to enable DMA for your drives. you can switch DMA (it should be on for HD) for CDROM/CDRW through /boot/loader.conf #sysctl -a | gep dma to see HDD status #sysctl -a | grep atapi to see CD status Guy Van Sanden wrote: Silly question Dany, how do I enable EHCI?

Re: USB 2.0 harddisk performance
Thanks Dany Is firewire fully supported on FreeBSD? The disk does have a firewire link, I can buy an addon card for about 30 ¤, but I wanna make sure that it will work better.

Re: USB 2.0 harddisk performance
Have you enabled EHCI support ? Even with EHCI enabled the speed won't be that great. According to the man page, the code is still under development and therefore pretty buggy.
