I'm going to build a computer for my small business and all i will be doing is email up loading and downloading pics and invoicing i need a lot of storage and want to set up raid so i don't have to worry about losing so which raid set up would be best i was thinking of three 1TB seagate baracuda st1000DM003 drives in raid 1 and then just use a 120gb hd for my os is that a bad idea is there a better idea i can add more drives if raid 10 would be better but as its my first experience with raid i didn't know if i should try that or if it would even be worth it or maybe you cant mirror 3 drives im not sure please let me know what you guys think or if there's a good place i can educate myself on this before i order parts
