With all these layers, efficiency starts to drop off.

Then we have another protocol layer, like TCP or UDP which has some amount of overhead of its own and still yet another layer, in this case, for SMB (aka Windows networking and file sharing). Then once we look at the payload, we still have overhead for the network protocol being used (IP, most often) which has more overhead of its own. Every frame sent has a preamble and delimiter, a header containing source and destination addresses, the data payload, followed by error detection code. The problem remains, though, that ethernet simply isn't that effecient. Using a switch instead of a hub will at least eliminate CSMA/CD overhead, which can get very high depending on the number of nodes in the collision domain. You can't just divide the signalling rate of 1,000,000,000 by 8 and declare that 1000TX will deliver 125MB/s. Gigabit Ethernet will not be fast enough for HD editing as it is only ~100-120MB/s and you would need to back it all up on another device in the event of something going terribly wrong. The only down side to this is that you will have pro grade equipment which will be more complicated to work on and maintain.Ĥ) use a pair of internal SSDs in RAID-0 (~900MB/s of throughput) and do local editing, but depending on your space requirements this could get expensive very quickly. This would give you ~400MB/s and would be more than fast enough for a good long time (this is what I am attempting to do). Consider internal RAID to get better throughput, but if you are like me and the noise would be an issue then you need to look at a few other options:ġ) a long KVM wires to keep the computer in a different roomĢ) bonding or ganging 2 gigabit ports for a total of ~200-240MB/s which is acceptable for HD editingģ) look for businesses that are upgrading old 4Gb/s fiber that they would be willing to sell you. but it is not as fast as I think you would like it to be. Gigabit Ethernet will not be fast enough for HD editing as it is only ~100-120MB/s which is slower than a single internal drive. I am getting ready to implement something like this over the summer. My other question, and i know im being needy so thank you to anyone who has taken the time to read down to this point, is how do i setup a RAID 5 in ubuntu as im only a linux novice, and how do i set it up as fully shared network storage.

will i be able to get the potential speed from the drives by limiting myself to gigabit ethernet? also would it be smart for me to edit straight off of the network drive? would it be possible to use both gigabit ethernet ports on my mac pro, and add another gigabit NIC to the pc to double the transfer rate? how would i do load balancing on the mac and ubuntu computers? My plans are to use the 1tb raid in the mac pro as the fastest data then move projects when im idle with them to the pc raid 5 for speed and redundancy.
my mac pro has gigabit ethernet also.ĥ00 GB 5400 RPM 2.5" SATA DRIVE with UBUNTU 11.10 (soon 12.04)Ģ50GB Western Digital SATA boot drive with OS X Snow Leopard 10.6.8 after looking at everything i have decided i would like to put four 1TB drives in my antec 900 case with a phenom x3, 4gb of ram and a gigabit NIC. right now i have two RAID 0's in my mac pro and am booting off of a esata external enclosure. I want to do RAID 5 because of its ability to rebuild and the fact that in a four disk solution i can get 3X the speed of a single 7200 rpm drive. I need to create a video editing storage solution after my move to much larger HD files.
