I had a 250 gb backup drive die on me last week and while I didn't lose anything important (the client files and family pictures were backed up on two other drives, all I lost was some pirated software.) it reinforced my desire to get a basic raid system set up in my basement. I don't want to build a whole new system and have to set up the raid myself with a raid controller if I can help it... mainly to avoid the cost. From what I can tell it would run me at minimum around a grand to set up a decent DIY raid system. I can pick up a refurb Buffalo TeraStation Pro 1TB for $400ish with the drives already in there... I sent an email to their support to see if I can upgrade the drives in the future if I'd like (to say 4 500gb ones.) This seems like a much more economical way to go about it... although I suppose if you factor in the cost of the future upgrade, perhaps not. What would you suggest? I'd obviously like to be able to backup as much as possible as soon as possible to avoid any future data loss. I can build my own raid server if it cost effective.
