LaCie has posted Silverlining Pro 6.4.3, as noted by VersionTracker, an update to the software and drivers for its USB, FireWire, and SCSI hard drives. The new version adds support for its USB 2.0 drives (although they only function at USB 1.1 speeds on the Mac), improved striped RAID performance, improved FireWire performance, and more. LaCie has also responded to user complaints regarding its Web site and now allows users to download updates without having to login or register.
