I currently have one internal harddrive on my system and the OS is CentOS 6. I am building a small dedicated web server to host one domain. The domain doesn't necessarily have to be online 24/7. I am considering purchasing a second internal HDD. I will definitely install a linux distro. I wanted to know if it is possible to run both harddrives simultaneously. Is it worth the extra money to get an SSD? Is it worth the money to get a 1 TB or just a regular 350 gb? I am leaning towards a different distro for the 2nd HDD. Do different distros complement each other? Does anyone know of any good article links that discusses having two internal harddrives on a desktop? Arr there any specific spec requirements that need to be addressed with installing a second internal? any help is appreciated.
