Thunderbolt 2 Express Dock HD
Belkin’s second-gen Thunderbolt dock is smaller and faster all-round
Thunderbolt docks enable you to connect multiple devices by plugging one cable into your Mac. This second model by Belkin looks similar to its first, but it’s more compact and has enhancements, including Thunderbolt 2 ports (but no FireWire).
We tested transfer rates from an eight-disk storage array connected to a Mac, and then through the dock. They dropped by no more than 34.8MB/sec. Even if you don’t plan to buy such fast and expensive storage, the dock’s Thunderbolt 2 ports enable a 4K display to be connected through it, provided your Mac supports the resolution.
Belkin’s old dock limited USB performance to about 200MB/sec, but that isn’t the case here. Our test SSD reached the same rates as older docks – but no faster, and the fastest SSDs still reached higher rates when connected to a Mac. The dock works with older Thunderbolt ports, too – minus 4K support, but without slowdown in USB speeds. There’s one USB port and a headphone/mic socket on the front, and a device can charge through the dock even when a Mac isn’t connected.
However, other Thunderbolt 2 docks have been announced, so it might be worth waiting to see what’s on offer. Alan Stonebridge
Big performance improvements over the old model, but still lacking some finesse for use with a MacBook. A cheap solution for activity and sleep tracking, but next-gen wearables are imminent.
The Flash offers activity tracking and has a decent app.
To connect two displays (if your Mac supports it), one will need a
