Probably not. As I understand it, IDE interface chips (those on the drives, not the PC) are proven and dirt cheap and the software (drivers) is relatively simple. 1394 hardware and drivers are more complicated. And the biggest markets for disk drives - PC - all have IDE channels but not many have 1394 ports. Besides, 7200rpm ATA drives' max. transfer rates (43MB/s and growing) are getting near the max 1394a transfe rates (~48MB/s) Although multiple 1394 devices coexist on a bus much better than two ATA devices do... Hey, anyone know if the workstation makers - Sun, HP, IBM - are adopting 1394? -James To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-firewire" in the body of the message
