Xserve RAID Driver Update
Apple has released , which it says "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. Since the frequency of Xserve RAID cache flushing to the hard drives is reduced, it is strongly recommended that an Uninterruptible Power Supply (UPS) be used with the Xserve RAID to guard against the possibility of data loss in the event of a power failure."
