Pros: I thought this would be good for my linux firewall inside NIC. I bought one in November 08 to try and it worked great. It passed all my testing. I do this for a living so I was please to find a cheap X1, half height, 1G NIC that would work in a small case (Intels X1, 1G is a bit longer)
Cons: I bought 5 more of these in December and started to put them into clients firewalls I supply. TO MY HORROR THEY STARTED TO RANDOMLY LOCK UP THE UNITS! There is nothing worse than real production fails. There may be a timming issue with the motherboard I'm using or a problem in the Linux kernel since I did not compile any drivers, just used the default from my firewall distribution which seemed to work fine. I now have 5 of the original 6 back in house to look at and remember all the wasted time and trips to clients. The next time I try and save $15 per machine I hope I get slapped just as hard.
Overall Review: I never tried this in XP so I can't speak for the true windows drivers or the card in that application. I'm really not sure if this is a linux driver issue, but I feel it is a timming issue on the X1 bus. To scarry when it works for hours then locks the whole thing up. This is based on a nightmare over 2 months and 6 deployed cards. Only 1 remains working - and I don't know why.
