Dear @Hilko,

Please kindly note that the T2600G-28TS and the TL-SG3424 are different models. T2600G-28TS is an upgrade version to the TL-SG3424, which is more powerful and has more advanced functions like L3 routing feature, Static Routing function, DHCP Server, etc.

For your inquiry, it's hard to answer with a simple YES or NO. It depends on your actual purpose of using the switch. If you need a router to work as the network gateway, then choose a router for use. If you don't need a router in the network but a switch with L3 routing feature could work for you, then the T2600G-28TS can be your choice.

You may check the specification of the switch from the official website and choose the switch that best suits your network requirements.

Hope the information above is helpful. 

Dear @Hilko,

My network will only consists of 1 (one) switch with a number of VLAN's (eg, {Port1 assigned to VLAN1 = Network Storage}, {Ports 2 to 5 assigned to VLAN2 = Users}).

I just want the users to be able to access storage from VLAN1.

The T2600G-28TS switch supports Layer 3 interface (interVLAN routing), which could meet the requirement that the devices in one VLAN can communicate with the devices in another VLAN. But the TL-SG3424 doesn't support it.
