The problem with hard drives
This is it in a nutshell - hard drives pack more and more data on a platter - but STILL only have one read/write head. This means that data can flow in and out at a maximum speed - and that data rate is the SAME for a 20Gb or 750Gb harddrive.

This means that a 750Gb drive cannot replace an array of 15 50Gb drives - because your data rate is reduced 15x. If you had a server that was running say, a dozen Oracle instances - using that array, you would NOT be able to use a single drive as it could not service requests fast enough.

Lets see, more space - same data rate. More cores - same gigahertz. Just where IS Moore's Law?
