I've got a dual 1ghz, 1gb system with 5x72gb drives, and am wondering what the best configuration would be for the drives/cache.
Since it has a hardware RAID controller, my initial inclination would be to go RAID 5 across all 5 drives (no hot spare), and after the OS, I'd be left with ~270gb for the cache partition. But I've been reading a few old posts and some people have suggested avoiding RAID.
Another possibility was to put Linux on 1 drive, then use a RAID 0 stripe across the other 4 drives for speed. Granted, if I blow any single drive in the box, I'm hosed - but I'll have 3 total boxes in a load balanced configuration.
Any thoughts?
Also - given the above 1gb RAM configuration, what is the largest cache size you would recommend? Should I use the available 270gb, or should I cut it off at some limit? I'll be using AUFS on Linux 2.4.
