Managed switches have operating systems and user interfaces. They are basically computers. You can program them, you can set them up for trunking or link aggregation, you can do vLANs, you can configure spanning tree, set up switch matrices, check port status, send manual WOL commands, etc.
Unmanaged, you can plug stuff in and have them see each other. That's about it
$138 switch - Buffer memory: 256K
Ports: 8 x 10/100/1000Mbps Ports
$310 switch - Buffer memory: 256KB per device
Ports: 8 x 10/100/1000Mbps Auto-Negotiation RJ-45 Ports
This one is bigger
And where does it say the first one is managed anyway??

D-Link 8-Port Gigabit Switch, Model DGS-1008D - Retail $138
D-Link 8-Port 10/100/1000Mbps Unmanaged Gigabit Switch, Model DGS-1008TL - Retail $310
The managed one is gigabit = 1000Mbps
Unmanaged = 10/100/1000Mbps = gigabit = teh same!
I expected better out of you prime.
