The drivers for the 828 and OSX do not support the Lightpipe interface yet, I understand they are coming tho. I have been using the Mercury series drives from Other World Computing, and have been able to manage around 50 tracks of 48K 24Bit audio on a Mac G4 733 with Logic 4.8.1, and only about 25ish on my 667 TiBook. I do get well over 50 on my PT 5.1.* with 6 farm cards. MacAddict had an article several months ago, a little shoot out with some firewire drives, and the OWC was square in the middle. The one drive that hammered it performance wise was like double the cost. I will have to look for the article. I might have a look at the drives from the guys at dageek.com http://www.dageek.com/sales/default.html, I know them and they make some pretty slammin' stuff. For a while they had these killer drivers that they designed and sold. Different caching was the real secret I believe. However there was some copyright problem - and I don' t know the current status. I imagine they(the drivers) still ship with the drives, but are no longer sold separately. aaron ---------------------------------------------------------------------------- ---------------------------- Everything comes to him who hustles while he waits.
