Raid or not in a server for personal use
I am quite happy to see responses / answers to query I make here, thanks to this beautiful community, I have one more small query.
I have few dedicated box and all have 2 drives, one for backup and other operating system. Since all my servers are never fully used, I never thought of using RAID, however now I feel that instead of wasting server's resources, I should set up VPS on it and use them separately so instead of buying 3-4 cheap boxes, I can do away with one little more powerful and that way I will also enhance my knowledge for managing vps.
The catch is, currently I am using second drive as backup drive (daily backups) and one of the server on other datacenter is storing weekly backups as all I have private clients. Now, if I get one big machines, eventually it will replace my 3-4 dedicated servers (so saving costs), now my budget is not that high that I should get Raid 10 setup which is most promising here..
So, should I go for RAID 1 (soft), will that be reliable enough or go for 2 disk setup as I do usually (1 for backup and one for actual use) , the main question is that, in Raid 1, your data is duplicated so both disks are used equally, so chances of failure of disks are equal.. isn't ?
Excuse if I sound ill-informed somewhere but RAID is thing which I am yet to use..
