Hey…adapters are always useful.

Late Tuesday, Apple added its new Thunderbolt to FireWire Adapter for newer Thunderbolt-equipped Macs at a US$29 price on the Apple online store.

The new adapter is estimated to ship in one to three business days. It allows users to connect their Thunderbolt-equipped Mac to a FireWire device with the small and compact cable.

The connector provides a FireWire 800 port that supplies up to 7 watts for bus-powered peripherals like hard drives and audio devices and can utiize two separate 10Gbps links — one for displays and one for PCI-Express device traffic — for throughput of up to 10Gbps between Thunderbolt-capable devices and a compatible Mac.

If you’ve tried the new adapter and have any feedback, please let us know in the comments.
