Not at all. A car with an automatic transmission is much easier to drive than a car with a stick shift. However, without proper training, you can hurt yourself and others with either. The Accusys boxes are very simple, seemingly reliable, but if you don't play with them for a bit and understand how they work, you can still can screw things up. IN FACT, there are so many neat things you can do with the Accusys boxes, you might be tempted to do something silly and wrong, believing that it will save you from everything. If you aren't willing to learn how the thing works, your overall reliability and uptime will probably be better with a single drive, no RAID at all. Sure, the drive could fail, but your recovery options will be very clear and direct. Nick.
