This adapter plugs into the Thunderbolt port on your computer, and provides a female FW800 port, for connecting to a FireWire cable.

Using this adapter plus a standard FW800 cable I can connect to my FW800 based external hard drives.
Using this adapter plus a 9-pin to 6-pin (FW800 to FW400) cable I can connect to my FW400 based external hard drives.

Works flawlessly - no problems running SuperDuper! or TimeMachine to my external hard drives via this adapter.

I'm admittedly an Apple fanboy, but it's pretty frustrating that I have to keep buying adapters for adapters... literally. With my new retina MacBook Pro, there are no FireWire ports. That's okay with me since the computer is thinner than the port itself, but I feel like the computer should come with a few adapters for FireWire and Ethernet. In any case, this connects the Thunderbolt port directly to FireWire 800 devices, but if you have a FireWire 400 device, you have to get a FireWire 800 to 400 adapter or cable.

This adapter does exactly what it's supposed to, i.e. allows you to connect Firewire hard drives to a Mac computer that has a Thunderbolt port. Be aware, however, that this adapter will only supply enough power to run ONE external drive at a time. If you want to daisy-chain multiple Firewire drives together through this one adapter, each hard drive beyond the first one will have to be powered by its own AC adapter. If you try to connect two hard drives that aren't AC-powered, the Mac operating system will freak out and instantly eject all the drives connected through the adapter.

I use this adapter with three drives attached at the same time and it works fine: two AC-powered drives and a bus-powered drive.

The Apple website states that this adapter provides up to 7W of bus power, so daisy chaining bus-powered devices is theoretically possible if you stay under the 7W limit - but I don't think you can find two hard drives that would consume less than 7W of power.

I do a lot of video editing and have three FireWire external drives that I use for scratch disks and file storage. I can connect them one at a time via the Thunderbolt adapter, but if I try to daisy chain two of them, my iMac disconnects from both drives. So, yeah, it lets me use a FireWire hard drive, but I can't move files between them. I have to copy them to my iMac and then over to the other disk, doubling the amount of time it takes to transfer files. When you're talking about many gigabytes of video files, that's a lot of wasted time. Apple claims FireWire devices plugged into the Thunderbolt adapter can be daisy chained, but I can't get it to happen. Maybe I'll just buy a second adapter; I have two Thunderbolt ports and the other one is just sitting there not doing anything. I shouldn't have to work around "improved" technology, though.

Just in case anyone else was curious about this, this adapter will let you do target disk mode between a firewire-containing mac and a mac with thunderbolt and no firewire (notably all of the Macbook Airs).

When traveling I frequently clone my primary machine whole to my Air, before this adapter I had to go through a complex and lengthy processes of cloning through intermediate drives. Now I can just mount the Air as an external drive and clone SSD -> SSD. Awesome!

While this adapter works with FireWire 800 portable drives, it doesn't seem to support daisy-chaining even 2 mobile drives together, which really limits the usefulness of this adapter.

This product allows me to use FireWire 800 devices on my MacBook Pro Retina through the Thunderbolt port. It is pricey but its the only option if you want FireWire on the new MacBook Pro Retina or other Macs with Thunderbolt ports instead of FireWire.

I use this for my 2011 MacBook Pro. Although there already is a firewire800 port, its nice to have two. Once for transferring files in and the other for going to an external hard drive. After running my tests, it runs exactly the same as the firewire 800, not any faster or slower.
