Storage is more than just a fast hard drive. There's many aspects to it, including partitioning schemes, RAID and its associated peculiarities, large-capacity (i.e. many TB) solutions, newer devices like SSDs, older but still necessary devices like optical drives, server-specific storage questions like SCSI, iSCSI, Fibre Channel, etc.
I would think with an issue that covers so much that a storage forum would be a good idea. Its a bit too broad of a subject to be thrown into General Hardware along with mice, keyboards, & power strips.
Perhaps the enthusiasts/gamers are more interested in CPUs & video cards, but some of the rest of us do different things with our computers. Many people are trying to set up home media servers now, and >2TB arrays is an important concept. It's a topic that belongs squarely in a dedicated storage forum.
