I have an interest in two network adapter products;
1) Intel Manufacturer product # PWLA8391, single port 1Gb ethernet network adapter which wholesales for $26
2) Intel Manufacturer product # E1G42ETBLK, dual port 1Gb ethernet network adapter which wholesales for $142.
I can not understand why would anyone buy the $142 dual port model if they could buy two of the $26 model.
There must be some performance difference between those two configurations. Could anyone explain, what that
Thank you for contacting Intel Customer Support.
Yes, you are correct. The E1G42ETBLK, being a server adapter, has more new features available compared to the PWLA8391GT, which is a desktop adapter.
Some of the features available in E1G42ETBLK Adapter are support for virtualization technology, teaming, latest operating systems.
