I've been contemplating converting my 2 disk raid1 to a 4 disk raid5. Couple of questions to those in the know. Machine: Intel P4 1.5Ghz Stepping 02, 512meg ram, 2-WD 80GB UDMA/100 raid1 mirror using debian testing. Usage: General office/campus use as a samba file server. About 150 PC's connected to it with maybe 20-30 users max performing simultaneous read/writes. Activity is mostly database type with small read/writes. Others are accessing office type documents. With a 4 disk raid5 array (safety matters ya know). Will I notice a huge difference in read/write speed from what I have now or just nominal? Does SATA vs ATA make a big difference? I'm pretty sure the bottleneck at this point is the sluggish disk access but how can I verify that it's the disks and not a saturated network connection? I've been using a utility called bwm-ng to monitor bandwidth and have not seen it come close to the 100mb/s that my NIC is rated. Thanks for any insights.
