The only writing to the drives, will be weekly batch jobs running at night. I originally planned to disable all or at least most loggin, but I changed my mind to allow for logging to an NFS volume on a separate management segment. Thus, there's virtually no writing in the system while it's running. Therefor - again - I'd like to run software RAID 4, as this'll give me read access to what looks like a RAID 0 (the n-1 data drives), and although writing will be a pain in the ass, reading will be fast, and I have some sort of redundancy.
What would you think would be a good stripe size in these circumstances (>=1GB files)
