IDE/SATA or SCSI ? >From my experience it seems that the lifespan of IDE/SATA hard drives in Servers that run 24h/day is between 2 to 5 years, SCSI runs for 3-12years.
So if you plan to do a HD server refresh every 2-3 years, you should be fine with IDE/SATA drives. I am personally a big fan of Promise raid controllers as Raid1(mirror). They are rock stable. I never had a faulty controller and I worked once for a promise distributor for 2 years. Please do not use raid5 if you don't have to. I had several problems including data loss. It was always a HD fault but it wouldn't have happened in Raid1. Today's HD's are big enough to run them as a mirrored raid1 Here is my configuration(2 years old): Promise Fasttrak66 with 2x30GB HD. Every month I shut down the mailserver, replace 1 HD with the spare and reboot. Within 45 minutes the server is synchronized and I have a working copy on the removed HD in case of a virus/hacking/complete crash disaster. So in case of a total breakdown or fire you will have your system restored and back online with the spare HD and the latest backup from tape within 2 hours ! Also the good thing about promise and RAID1 is that you can have it all hot-swappable with the proper enclosures. I even know a big hosting company who does just HD hotswap as backup. So they can achieve an uptime of nearly 100%.
