2.5 vs 1 gbit Ethernet nic
- Thread starter kickstart24
- Start date
If it’s the same cost go for it but it probably won’t make a difference; your bottleneck will be your hard drive and file system.
If you are talking on your physical lan ie lan interconnections. Until you update the switches it wont matter unless you are using LAGG. Since I doubt LAGG is need it would just auto negotiate down to the speed of the connection on the other end. If you are connecting BI directly to the router it might help interconnection speed but that is about all. Plus most cams are 100 Mbit anyway.
Also as an aside unless you have a internet plan above 1 Gigabit. The 2.5 nics dont help there (as in internet to PC) either. I wasn't clear enough here I suppose. The internal LAN can be whatever you build it to. I said this above. I you have a 1 gig internet plan the speed of the connection is fixed even if you have a 10gig lan. The internet speed will still be at 1 gig.

1 Gb should be good enough for security camera needs for nearly all of us here .. there probably are a few people running massive amounts of cameras and video feeds, but I seriously doubt I have seen those folks post here.
The 2.5Gb might be useful longer than a 1Gb nic, depending on your future network needs, especially if the cost is comparable as @Underhill mentioned.
Do you foresee a need to transfer large amounts of data from your BI PC to somewhere else? A 2.5Gb nic may help reduce transfer times, depending on your system/HDDs etc. if that is a possibility.
I've been considering a NAS for my network and on some of the systems the 1Gb nic is a bottleneck, again depending on the HDDs, especially when transferring large amounts of data. Upgrading the 1Gb nic to a 2.5Gb increased the transfer rate and made the HDDs the limiting factor.

It depends.
What will the NIC be used for? Most people here (I think) use 2 NICs, one for the camera network and one for the LAN network. For the camera network, you probably would not benefit. I am running 16 cameras (I think) and I am nowhere near to even utilizing 1Gb for the camera network.
If its for the LAN side, a 2.5Gb NIC will be very useful, as you can then export clips 2.5x faster than before (Or a little under, as most modern hard drives can read at around 200MB/s which is 1.6Gb/s) and it also means you won't be maxing out the link when exporting video. Of course viewing the cameras is using bandwidth, so if you have 4 people viewing UI3 and exporting a video, the 2.5Gb NIC will be useful.
But, will you have a 2.5Gb switchport to connect it to, so will it link at 2.5Gb? Either way if the NIC is cheap enough, just go for it. However, if the 1Gb NIC is Intel and the 2.5Gb is Realtek etc, go the 1Gb Intel. Quality over speed!
I have a 10Gb connection for my BI Machine
File system has nothing to do with it, and most hard drives can easily max out a gigabit link
You internet has nothing to do with local network speed, else my 25Gb SFP28 and 40Gb QSFP+ connections would be useless!

Pizza, most people don’t have raid 10 ssd arrays, and if you think file system has nothing to do with it, try some benchmarks between Fat, NTFS, exfat and ext4.

Who said anything about a RAID 10 SSD array? no idea who's recording to FAT or exfat, but ext4 and NTFS can clear 10Gb+ easily
Did you bother to read my post where I outlined my justification and hard drive speeds etc?
