Doesn't Wiki say that RAID 5 protects you from data loss from 1 failed hard drive?
It does but that's not a backup. Again, what happens if you accidentally delete a file from your RAID array? How's RAID going to get it back for you? Hint: It's not.

RAID 5 is a fault tolerant system that does protect your from a single drive failure. RAID 5 is designed to only protect that data changed or added since the last backup and nothing else.
But, (and it is a big but) the single greatest reason for data loss is human error, a.k.a. the "oops factor", then factor in all the other non-drive failures, from software (application and OS) crashes, viruses, worms, deliberate attacks, unintentional acts, controller failures, power spikes-outages, corrupted partition tables, MBRs, theft, fire, natural disasters,.......... well there is the short list, hopefully you get the idea.
Drives today are pushing the limits of data density, and they are electro-mechanically devices that are made as cheaply as possible, or "just good enough", to keep the cost down (read competitive).

I never accidentally delete stuff, so I'm not worried about human error. ALL of my data loss occurred because of hardware failure or loss.

Stay away from Seagate Drives people! THEY STINK AND ARE FAILING A LOT!!
RE: RAID, try re-reading my post. Your opinion on Seagate is just that, opinion, I've used nothing but Seagate in my own systems and it's all we use in our custom builds at work and we've had very good results with them.
