I'm putting in a new switch for my home network. Right now, 8 ports is plenty; in future, I'll need 16 or maybe even 24. In the range I'm buying, the 8 port switch is about £40, but the 16 port is £105, and the 24 port about £180. Rather than buying big now to protect for the future, it's cheaper to buy small, and add more 8 port switches in future.
To make this work, I'll need to cascade the switches. All the kit is gigabit ethernet, which is way faster than I expect to need for domestic use, so I don't expect any bottlenecks. Is this OK, or is there a catch? Have I missed something? I'm struggling to see why the bigger switches cost more per port.
