I agree with that post as it relates to RAID 0, but to be clear, we are talking (with Raptech) about RAID 1. Again "assumed" zero performance hit (good or bad) and instead, you have added a level of safety. However, as per the article, my thinking did change from doing a Raid 5 to something else. Raid 5 - you have 4 drives but you get only 66% of the space so 4x1TB = 4TB = 4192GB. At 66% you would get 2766GB free space (not great). For that, you can lose ONE drive and still be fine. I was looking instead of either doing a RAID 1+0 or maybe trying to see if I could just get 2 sets of RAID 1s. This would be used for a media center where it takes time to load it and/or recordings over time, but totally impractical to backup. RAID 5 was a problem because to get that level of RAID you need to spend money for a controller card and they are not that cheap. RAID 1 - cheaper controllers and/or onboard MOBO RAID. As per RAID 0, RAID 5 and other flavors nowadays are less of a concern due to the cheap cost of media. That is why I just said F'IT - spend $350 and have a RAID 1 2x2TB system for offline backups and be done with it. I will say, however, that they do sell towers that hold 4 drives and you could take a bunch of odd sized drives and create one big drive using JBOD (Just a Bunch Of Drives). I could do that - I have a bunch of older 120GB drives doing nothing, but the cost to buy a tower, for what - 480GB of old unreliable storage - the tower would cost me probably $50-100. For $100 I can buy a 2TB drive. JBOD doesn't really make much sense either. Great discussion. B
