Hi!
I'm planning to build a home made NAS using old harware and SUSE. SUSE might not be the best OS for this, but it's the only Linux I have administered at least somewhat.
Ok, what I'm thinking is a old PC with lot's of old disks inside and a gigabit ethernet (planning to do video editing over it also).
Even gigabit ethernet is WAY slower than local disks. You may find it a pain for video editing. It might be OK to store video there, copy it to a local disk while you edit it and then copy it back. But the bottom line is experience - I suggest you set up the gigabit link and run some tests with it first :)
Cheers, Dave
I haven't seen the original posting so this response is to HG.
Forget about using the gigabit ethernet way of transferring video files let alone trying to do editing of video over such a link. Just transferring a small ~4GB mpeg file will take about 45 minutes (from memory, so don't quote me :-) ) and this using HDs with 16MB caches on both computers at the end of the gigabit connection. After falling asleep while one such transfer was taking place I gave the whole idea away and now only work on the one computer :-) .
Your system ist probably not set up to truly utilize GBit throughput. If you really want to use transfer rate of a GBit connection to the limit you must have a matching system. Use an onboard nic not connected to the pci bus or a dedicated pci express nic and as a storage system something like a good pci express hardware raid with bbu and several disks in raid 0. This is definitely not cheap but it will ensure that you have a sustained transfer rate of about 100 MB/s. Currently I only have one system with that kind of power, so I can't test it. Even if I would just set another GBit nic in another computer, the second system just can't match the first. :-(( Sandy -- List replies only please!
