Just so I am making the right decision and not confused I would like to know if I am picking the right Raid. I think I want Raid 5. I am going to buy three Western Digital VelociRaptor WD1500HLFS 150GB 10000 RPM 16MB Cache SATA 3.0Gb drives. I want to stripe with Raid 0 for speed but want Raid 1 for reliability. I first thought of Raid 1+0 but from my understanding Raid 5 would be better. I could go Raid 6 but would have to buy another drive and can't see the benefit of the extra money over 3 drives with Raid 5.
Am I understanding all of this correctly or can you have two drives in Raid 0 and a third that mirrors the data with out striping????? I just want it to be super fast (without spending the extra money for SCSI, which I know is faster) Could someone tell me the pros and cons in a simple 3rd grade explanation sort of way[/u][/u], as to which one I should use to be the quickest most responsive but still be reliable. This is for my business for my host computer where I have three other computers accessing it and we store all our files on it for safe keeping. I have two USB 74 gb storage drives that we back up once a week so we don't lose everything if something happens.
If Raid 6 is the better option, I could buy another drive, they are not that much. I just wants whats best for my application. The more I research the more I get confused. I plan on using Areca Technology- ARC-1110 PCI-X 64bit/133MHz SATA II Controller Card RAID level 0, 1, 1E, 3, 5, 6 and JBOD controller card.
Please add you 2 cents. I am all ears. Thanks
