Gigabit Ethernet cards will work faster that 3 or 3 times faster in almost all circumstances. But anyway, back to the original question.
I don't know how much you know, but heres a quick education on hubs/switches:
-Hubs increase the size of the collision domain (not cool)
-Switches decrease the size of the collision domain (cool)
-Switches are a cheap way to increase overall bandwidth
-Hubs are crap
The switch you showed will work. There is no reason why it would not. However I would consider getting a Gigabit ethernet switch. Because it will mean that whenever you get a new node that is capable of Gb, it will be able to operate in that mode. The switch will end up the bottleneck of the network in the future, so plan ahead!
