LSI has released a Mac OS X driver for its 3ware 9690SA and 9650SE series RAID controller cards. The controllers enable Mac server users in directly attached storage environments to optimize reading and writing performance while streaming digital video, digital audio, and film. The device's StreamFusion firmware utilizes an Advanced Content Streaming feature to divide total bandwidth equally among various streams, allowing the devices to sustain multiple streams with large amounts of data. The controller's firmware also includes an Intelligent Read Prefetch feature that enables data to be retrieved from media and stored on the controller in advance of the data being requested by the host.

The controllers also provide internal and external connectivity for SATA and SAS hard drive systems and are available in various port configurations such as a full line of SATA controllers and low-profile SATA and SAS controllers.

The LSI 3ware controllers are available through a variety of retailers. The Mac OS X driver and StreamFusion firmware is available to download for free from the 3ware website.
