I am building a Windows 2008 R2 server which will host both Microsoft SQL databases and websites on IIS. Most likely a Dell R710.
I want to go with a RAID 10 for a mix of security and speed. I don't think I'm going to need too much space (databases are mostly text based, will be 1 GB or so at most).
Price-wise I can either choose 6 x 146 GB 15K RPM or 4 x 300 GB 15K RPM hard drives, there is barely any difference in price. The 4 x 300 obviously gives me a bit more space, but that space is most likely going to be unused anyways.
Therefore my question - should I go with the 6x146 or the 4x300 configuration? Are there any benefits to go for more smaller drives? If so, how significant are they?
Thanks!
