I'm looking to build a NAS unit for my home network, and I'm trying to decide on the mobo/CPU combination and RAID controller.
My current choices are:
Mobo/CPU combo
RAID Controller
Now, I've been reading a lot in recent years about "software RAID", such as that on motherboards and, from what I've read, this card. Most sources seem to say that software RAID tends to have much more CPU overhead than "true" hardware (i.e. enterprise server grade) RAID. This however is way out of my price range, so I'm stuck with this type of solution.
My basic question is: given 4x 750 GB Western Digital Green Power SATAII drives running in RAID 5 and that RAID card, would the 1.2 GHz Via Eden CPU on that system (with a full 1 GB of RAM) be sufficient to serve the large array over gigabit ethernet?
Other info: The system (Ubuntu Server 7.10 most likely) will be running from a separate USB key/CF card on the server so it is of no consideration here. File serving and BitTorrent (uTorrent under WINE, managed through a web interface) are all that this system is going to be doing. The FS will vary by partition (at least 3 partitions; movies, music, files) between EXT3 (music and files) and XFS (movies).
