MPG will be testing the Thunderbolt 2 Thunderbay soon.
Do you need Thunderbolt 2 speed?
Daisy-chaining = connecting devices in series to each other, versus direct connection for each to the host computer.
Thunderbolt 2 is twice the speed of Thunderbolt, but what are the practical implications? See 2013 Mac Pro: Thunderbolt Performance Tips as well as these summary points.
- For hard drive solutions, Thunderbolt v1 an v2 offer no significant difference in speed, because the hard drives are not fast enough to need it. Even four hard drives capable of 200MB/sec (very fast) do not max-out Thunderbolt v1. And that's assuming all four are in use simultaneously.
- With Macs like the 2013 Mac Pro, there are enough Thunderbolt ports that connecting a Thunderbolt v1 hard drive solution directly (without daisy-chaining) is fast enough as per previous point.
- Daisy-chaining any two or more high peroformance solutions should use Thunderbolt 2 for best performance.
- For SSDs, Thunderbolt v2 offers appreciably higher speed for simultaneous use of two or more SSDs, since some SSDs do have the speed to need the bandwidth.
- Systems with only two Thunderbolt ports such as the MacBook Pro really only have one Thunderbolt port if an external display is used, hence daisy-chaining and high performance devices make Thunderbolt v2 a better choice.
- Users of 4K displays require Thunderbolt 2 for 60 Hz operation if the display is daisy-chained to another peripheral (not connected directly to Mac).
