Why not go the whole hog and put all the drives in a RAID-1 and have 4 copies of all your data? For a mail server, database server, or other machine where you can only have one copy of the data you want to be really paranoid about the drives. For a web server I suggest having two servers. Use RAID-1 for simple mirroring of the data (if only to save yourself the effort of reinstalling a server after a minor hard drive error). For anything serious have load balancing at the switch or have a manual take-over proceedure to make the other machine get both IP addresses. Having a redundant server saves you from memory errors, CPU over-heating, and other hardware problems (which are probably more likely than having two hard drives die at the same time). -- http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/projects.html Projects I am working on http://www.coker.com.au/~russell/ My home page
