The PIX-DOCK is a convenient solution allowing you to connect a Sound Devices PIX-CADDY 2 (the one you use with the PIX 220, PIX 240 and PIX 260) to a Thunderbolt equipped Mac. A single Thunderbolt cable (a 6 ft Thunderbolt cable is included) provides both power and data transfer.
The PIX-DOCK connects to the PIX-CADDY using its eSATAp connection so you will not see faster transfer speeds if you’re already using an eSATA connection. For example, if you have a MacBook Pro with an ExpressCard/34 slot and have been using an eSATA card like the Sonnet Tempo SATA Pro ExpressCard/34, the PIX-DOCK will not speed up your downloads. But for that nice new MacBook Pro with Retina Display or any other Thunderbolt equipped Mac, the PIX-DOCK is a great convenient option.
The PIX-DOCK is on sale now with an MSRP of $375 though it looks like you can find it for a little less online.
