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
want to set up raid for a work computer need help

The value of raid-1 and it's variants like raid-5 is that you can recover from a drive failure quickly. It is for servers that can not tolerate any interruption.
Modern hard drives have a advertised mean time to failure on the order of 500,000+ hours. That is something like 50 years. SSD's are similar.
With raid-1 you are protecting yourself from specifically a hard drive failure. Not from other failures such as viruses, operator error,
malware,raid controller failure fire, theft, etc.
For that, you need external backup. If you have external backup, and can tolerate some recovery time, you do not need raid-1

any raid makes work computer faster(helps faster find computer required information)nothing else its not makes files safer.if you worry abouth loosing information when hardware or software (or other fails),fails.you wanna back up your data.theres is no other way.
so from what you guys are telling me it would be a waste to use raid for a back up...just curious because a second hdd is about the same price as an external hard drive and it wouldn't require me to back it up manually i do see your point about viruses though as far as speed goes im not that concerned i have another pc that I use for things of that nature
RAID-1 is usually done with two drives (mirroring). Three and more drives are used in higher RAID levels (RAID-5).
As for your setup: It depends who will provide the RAID functions. Some motherboards have hardware support for RAID0 and RAID1. I got brand-name desktop with two drives in RAID1 setup (mirroring in hardware). This was usefull when one of the drives failed - I was able to start my system with just the other drive, and had all my data intact.
Another option is to get specialized controller for RAID support, but chances are it might operate disks in such a manner that they will be unrecongisable in stand-alone mode.
As others mentioned, RAID is not panacea - you still need a backup plan. Plan for big-enough external drive for backups only, and suitable software.

the mobo is a MSI A78M-E45 FM2+ / FM2 AMD A78 (Bolton D3) SATA 6Gb/s USB 3.0 HDMI Micro ATX AMD Motherboard at least thats what im looking at right now and it supports raid 0 1 and 10 so i would be okay there but i think i will use 2 1tb drives in raid 1 and then get a 1tb external drive as a back up with that i should be covered or is there something eles i should do too... im not new to computers but i am new to backups as i have never had any info on a computer that i would be upset if i lost i mostly just built gaming computers so i do appreciate the help
