The 828mk3 Hybrid provides virtually identical features to the 828x (including USB 2.0 support), except that instead of Thunderbolt, it provides FireWire connectivity to any FireWire-equipped Mac or PC. The connectors are “Type B” jacks typically used for FireWire 800, but they operate as standard FireWire 400 ports and are compatible with any FireWire port on your computer (A or B).
