Since my internet speed is capped at 100mbps, I don't need gigabit speeds for this NIC. Is this a good choice? If not any other recommended ones?
But please don´t forget that you will be even speaking about real and theoretical "speed"!
A 100 MBit/s card is serving something around 80 MBit/s like an older Alix Board (not the APU) A 1 GBit/s card is really able to delivers something around 450 to 750 and more and there for Iwould consider to go with a 1 GBit/s network card.
Yeah so isn't "server-grade" NICs more reliable than standard consumer NICs?
For sure, but not in all scenarios and fields! Server NICs or hardware often comes with a so called
digital signal processor soldered on the NIC, and is there fore taking much load from the CPU.
I would still expect server hardware to cost more than consumer-grade hardware.
Consumer NIC = small onboard soldered Chip for the network parities
Server NIC = Digital signal processor onboard soldered
The chip can do less and is less expensive too.
