Apple Xserve RAID Driver
Apple Xserve RAID Driver 1.0 for Mac is available as a free download on our software library.
From the developer:
The Xserve RAID Driver Update should be installed by all Final Cut Pro users using an Xserve RAID. The update reduces I/O WRITE latency by overriding behavior to periodically force the Xserve RAID to write its buffer cache to the hard drives. Lower I/O WRITE latency improves performance during video capture and is required to avoid dropping frames regardless of the video resolution used.
