Multiple Hard Drives Working Together: All About Raids

Incorrect, With RAID 1 you can expect double the read speeds as the RAID controller can read from both drives at the same time asking for different bits of information from each.

I'd like to hear their "Defination" of Backup Before they challenge RAID 1.
RAID 1 has Never failed me in the past.
With my New computer I'm going to use RAID 5 (4x 2TB drives), which will give me More redundacy than RAID 1.
Let the Bashing Begin!!!!

I’m not bashing you here. It all depends on what you consider a backup is and how much you cherish what you want to preserve. RAID 1 may work for you if you don’t have a bunch of data files that are important to your existence. My definition of backup is to have my important files copied to an external source outside my physical location. Some people use Cloud services, but I’m not that trusting of these services as some are. I have a system of backup drives tied into my network system and not subject to common catastrophes such as fire, robberies, lightning strikes, etc. Nothing is absolutely foolproof these days, but you have to consider file value and react accordingly. What I have is probably overkill for most people, and costly even for me, but I sleep better at nights and that might be the deciding factor on what you consider adequate.

What some people fail to consider, however is that "bad writes" caused by software/OS will damage the data on both drives. RAID is *hardware* redundancy *only*, and offers no protection against soft damage. That requires data backups of some kind...
